Introduction

Scope of ManualThis instruction manual includes installation,operation, calibration, maintenance, and partsordering information for the 3582 Series pneumaticvalve positioners, the Type 3582i electro-pneumaticvalve positioner, and the 3583 Series pneumaticvalve stem position transmitters. Refer to separateinstruction manuals for information on the controlvalve, actuator, and accessories.

No person may install, operate or maintain a 3582Series pneumatic valve positioner, a Type 3582ielectro-pneumatic valve positioner, or a 3583 Seriespneumatic valve stem position transmitter withoutfirst D being fully trained and qualified in valve,actuator and accessory installation, operation andmaintenance, and D carefully reading andunderstanding the contents of this manual. If youhave any questions about these instructions, contactyour Emerson Process Management t sales office.

Description

The 3582 Series pneumatic valve positioners andthe Type 3582i electro-pneumatic valve positioner

shown in figure 1 are used with diaphragm-actuated,sliding-stem control valve assemblies. Thepneumatic valve positioners receive a pneumaticinput signal from a control device and modulate thesupply pressure to the control valve actuator. Thepositioner adjusts the actuator supply pressure tomaintain a valve stem position proportional to thepneumatic input signal.

Type 3582NS positioners are designed for nuclearpower applications. The Type 3582NS constructionincludes materials that provide superior performanceat elevated temperature and radiation levels. TheO-rings are EPDM (ethylene propylene) and thediaphragms are EPDM/NOMEX R fabric. EPDMdemonstrates superior temperature capability andshelf life over nitrile. The NOMEX diaphragm fabricdemonstrates improved strength retention atelevated temperature and radiation conditions.

CAUTION

Use a clean, dry, oil-free air supply withinstruments containing EPDM

components. EPDM is subject todegradation when exposed topetroleum-based lubricants.

Under Fishers R 10CFR50, Appendix B, qualityassurance program, Type 3582NS positioner isqualified commercial grade dedicated. These canbe supplied as 10CFR, Part 21 items

The Type 3582i is an electro-pneumatic valvepositioner, consisting of a Type 582ielectro-pneumatic converter installed on a Type3582 pneumatic valve positioner. The Type 3582i

valve positioner provides an accurate valve stemposition that is proportional to a dc current inputsignal.

The Type 582i electro-pneumatic converter is amodular unit that can be installed at the factory or inthe field. However, do not plan to install a Type 582iconverter on an existing positioner until you contactyour Emerson Process Management sales office forapplication assistance.

Personal injury or property damagemay result from fire or explosion ifnatural gas is used as the supplymedium and preventative measuresare not taken. Preventative measuresmay include: Remote venting of theunit, re-evaluating the hazardous areaclassification, ensuring adequateventilation, and the removal of anynearby ignition sources.

Type 3582i does not meet third partyapprovals for use with natural gas asthe supply medium. Use of natural gasas the supply medium can result inpersonal injury or property damagefrom fire or explosion.

Note

All valve positioners and valve stemposition transmitters are shipped withfoam rubber packing material insidethe case. Remove the cover (key 33,figure 20) and the packing materialbefore attempting to operate the unit.Make sure all vent openings are clearbefore installation of the unit and thatthey remain clear during use.

Typically, the positioner or transmitter is ordered withthe actuator. If so, the factory mounts the valvepositioner or valve stem position transmitter andconnects the valve positioner output to the actuator.

If a Type 67CFR filter-regulator is specified, it maybe integrally mounted to the valve positioner or valvestem position transmitter, except for the Type3582NS positioner. For the Type 3582NS, the Type67CFR is separately mounted, not integrallymounted to the positioner.

Note

In some cases, alignment andcalibration of the valve positioner or

valve stem position transmitter at thefactory may not be possible, and fieldalignment and calibration is required.Before putting the valve positioner orvalve stem position transmitter intoservice, check the operation of the unitto be sure it is calibrated. If the valvepositioner or valve stem positiontransmitter requires alignment orcalibration, refer to the appropriatecalibration instructions in this manual.

If the valve positioner or valve stem positiontransmitter is ordered separately, disconnected, orremoved from the actuator, refer to the appropriatesections of this manual for installation information.

10. Position the travel pin so that it is perpendicularto the connector arm and aligns with the correctactuator stem travel index on the rotary shaft arm.Tighten the cap nut (key 62 in figure 3).

11. Check the travel pin setting using the followingprocedures:

D For standard travel pin setting (that is, withthe travel pin setting equal to total actuator travel).Stroke the actuator to each end of its travel. At eachend of travel, the 30-degree index marks on therotary shaft arm should align with the case indexmarks. If the index marks are not in line, loosen thecap nut (key 62) and slide the travel pin (key 60) inthe rotary shaft arm slot until the 30-degree indexmarks align with the case index marks. Be sure thetravel pin remains perpendicular to the connectorarm. After making this adjustment, tighten the capnut and re-check the arm at the mid-travel position. If the 0-degree index marks do not align, repeat this

procedure.

D For special travel pin setting (that is, with thetravel pin setting greater than total actuator travel).Check the index marks using a procedure similar tothe standard settings procedure. The arm will notrotate a full 60 degrees as the actuator is stroked,and the 30-degree index marks on the cam will beshort of aligning with the case index marks. If necessary, adjust the travel pin position so that the

30-degree marks are the same distance from therespective case index mark at each end of actuatortravel.

Changing Cam PositionRefer to figure 20 for a typical cam illustration andkey number locations.

Note

D For Valve Positioners: The smallarrow on the cam must point in thedirection of stem movement withincreasing actuator diaphragmpressure.

D For Valve Stem PositionTransmitters: If the arrow on the campoints up toward the nozzle, outputpressure increases with downwardstem movement. If the arrow pointsdown, output pressure decreases withdownward stem movement.If the arrow is pointing in the wrongdirection, use the following procedureto remove, reverse, and re-install thecam.

When mounting a valve positioner or valve stemposition transmitter, check to see if the correct cam(key 4) and cam position has been selected. To

Pressure Connections

WARNING

Valve positioners and valve stemposition transmitters are capable ofproviding full supply pressure toconnected equipment. To avoidpersonal injury or equipment damage

caused by parts bursting from systemoverpressure, make sure the supplypressure never exceeds the maximumsafe working pressure of anyconnected equipment.

Pressure connections are shown in figure 7. Allpressure connections are 1/4-inch NPT female. Use3/8-inch tubing for all pressure connections. Aftermaking pressure connections, turn on the supplypressure and check all connections for leaks.

Supply Connection

WARNING

Personal injury or property damagemay occur from an uncontrolledprocess if the supply medium is notclean, dry, oil-free air, or noncorrosivegas. While use and regularmaintenance of a filter that removesparticles larger than 40 microns indiameter will suffice in mostapplications, check with a Fisher Fieldoffice and Industry Instrument airquality standards for use withcorrosive air or if you are unsure aboutthe proper amount or method of airfiltration or filter maintenance.Type 3582i does not meet third partyapprovals for use with natural gas asthe supply medium. Use of natural gasas the supply medium can result inpersonal injury or property damagefrom fire or explosion.

CAUTION

Use a clean, dry, oil-free air supplywith instruments containing EPDMcomponents. EPDM is subject todegradation when exposed topetroleum-based lubricants.

Supply pressure must be clean, dry, oil-free air ornoncorrosive gas. Use a Fisher Type 67CFR FilterRegulator, or equivalent, to filter and regulate supplyair. Except for the Type 3582NS, the filter regulatorcan be mounted on the positioner. For the Type3582NS the regulator can be mounted on themounting plate with the positioner but not on thepositioner. The supply pressure should be highenough to permit setting the regulator 0.3 bar (5 psi)above the upper limit of the appropriate pressurerange, for example: 1.4 bar (20 psig) for a 0.2 to 1.0bar (3 to 15 psig) range. However, do not exceed themaximum allowable supply pressure of 3.4 bar (50psig) nor the pressure rating of any connectedequipment.

Connect the nearest suitable supply source to the1/4-inch NPT IN connection on the filter regulator (if furnished) or to the 1/4-inch NPT SUPPLYconnection on the positioner block assembly.

WARNING

Personal injury or property damagecould result from fire or explosion ofaccumulated gas if a flammable gas isused as the supply pressure mediumand the positioner/actuator is in an

enclosed area. The positioner/actuatorassembly does not form a gas-tightseal, and when the assembly isenclosed, a remote vent line, adequateventilation, and necessary safetymeasures should be used. For leakagerates, see the Maximum Steady-StateAir Consumption specification. Aremote vent pipe alone cannot berelied upon to remove all hazardousgas. Vent line piping should complywith local and regional codes andshould be as short as possible withadequate inside diameter and fewbends to reduce case pressurebuildup.

CAUTION

When installing a remote vent pipe,take care not to overtighten the pipe inthe vent connection. Excessive torquewill damage the threads in theconnection.

The vent opening at the back of the case markedVENT should be left open to prevent pressurebuildup inside the case and to provide a drain holefor any moisture that might collect inside the case.The perforated section of the nameplate normallycovers this opening to prevent blockage from debrisor insects. Also, ensure the exhaust holes in therelay (key 32 in figure 20) are kept open.

If a remote vent is required, the vent line must be asshort as possible with a minimum number of bendsand elbows. The vent connection is 3/8-inch NPTfemale. Use 3/8-inch or larger tubing to provide aremote vent. The 582i has a 1/4-inch NPT femalevent connection. Use optional remote vent 83LRelay for remote vent applications.

Valve Positioner Bypass OperationType 3582 and 3582D valve positioners, and Type3582NS positioners with bypass, are supplied with abypass assembly. A handle on the bypass assemblypermits selecting positioner or bypass operation.Refer to figure 24 for key number locations.

CAUTION

Do not use bypass when the valvepositioner is reverse-acting or is insplit-range operation. In these cases,bypassing the valve positioner sendsthe input signal directly to theactuator. Such a change will affect thedesired operation and possibly upsetthe system. Use bypass only when theinput signal range is the same as thevalve positioner output range requiredfor normal actuator operation.

Labels on the bypass block (key 34A) and a pointeron the bypass handle (key 34D) indicate if the inputsignal from the instrument goes to the positioner ordirectly to the control valve actuator. Push thebypass handle toward the back of the positioner tomove the pointer over the word POSITIONER. Withthe bypass handle in this position, the input signalgoes to the valve positioner bellows and the outputpressure of the valve positioner goes to the actuator.Pull the bypass handle forward to move the pointerover the word BYPASS. In this position, the inputsignal goes directly to the actuator.

Note

A difference between the input signalpressure and the valve positioneroutput pressure could cause atransient bump in the controlledsystem when the bypass handle is

moved to BYPASS.

With a reverse-acting or split-range valve positioner,the bypass handle may be locked in thePOSITIONER position so that bypass cannot beused. To lock the bypass handle in thePOSITIONER position, first shut off the instrumentand supply pressure to the valve positioner. Then,remove the hex head shoulder screw from the centerof the handle. Remove the handle and rotate it 180degrees and re-install it with the handle between thetwo lugs cast on the bypass block. Replace theshoulder screw.

Input Signal Ranges

Standard input signal ranges for valve positionersand valve stem position transmitters are shown intable 8. Changing from one standard range toanother requires changing the range spring. Tochange the range spring, refer to the instructions forchanging the range spring in the maintenancesection of this manual. Split-range operation of 3582Series valve positioners or the Type 3582i valvepositioner normally does not require changing thespring. Refer to the section below for split-rangeinformation.

Valve Positioner Split-Range OperationThe 3582 Series valve positioners and the Type3582i valve positioner are suitable for split-rangeoperations. In split-range operation, the input signal,either pneumatic or dc current, from a single controldevice is split between two or more control valves.No additional parts are required to use an existingvalve positioner for split-range operation.

Table 9 shows some typical split-ranges for thevalve positioners.

To change to split-range operation, perform thebeam alignment procedures then perform thecalibration procedure using the desired split rangeinputs that result in full valve travel. For example, fora 3582 Series positioner with a 0.2 to 1.0 bar (3 to15 psig) input signal range in a two-way split, a 0.6bar (9 psig) input signal should completely stroke thevalve for a 0.2 to 0.6 bar (3 to 9 psig) signal range.

Note

The flapper must approach the nozzle

squarely at the midpoint value of theinput signal range for properoperation.

On some applications where the inputsignal span is comparatively small (asfound with split-range applications),the nozzle adjustment may not beenough to set the proper startingpoint. Also, some difficulty may beexperienced in keeping a valve

positioner from unloading when theinput signal continues to increaseabove the split-range.

For example, for a 0.2 to 0.6 bar (3 to 9psig) input signal range, the inputsignal could increase to 1.0 bar (15psig). Continued bellows travel due tothe increased input signal over thesplit-range would drive the flapper intothe nozzle. The impact could possiblycause misalignment between theflapper and nozzle. Such amisalignment, in turn, could affectsplit-range calibration.

In these cases, adjust the followerassembly screw in addition to thenozzle adjustment to obtain

satisfactory results.

Note

The 3582 Series valve positionersrequire a relatively small percentage ofthe instrument pressure span to obtainfull valve travel. With the travel pin setto equal the valve travel, the inputsignal change required to fully strokethe valve can be reduced to 33 percentof normal input signal change. Withthe travel pin set to a value greater

than the valve travel, the input signalchange required to fully stroke thevalve can be reduced to a minimum of20 percent of normal input signalchange.

Changing Valve Positioner ActionConverting a 3582 Series valve positioner or Type3582i valve positioner from direct acting (anincreasing input signal, either pneumatic orelectrical, increases output pressure) to reverseacting (increasing input signal decreases outputpressure) or vice versa requires no additional parts.The position of the flapper assembly on the beamdetermines the action. As shown in figure 15, thebeam is divided into quadrants. The direct-actingquadrant of the beam is labeled DIRECT and thereverse-acting quadrant is labeled REVERSE. Tochange the positioner action, simply move theflapper assembly to the opposite quadrant of thebeam. Perform the calibration procedures in thevalve positioner calibration section.

Changing Valve Stem PositionTransmitter Action

Refer to figure 20 for key number locations unless

otherwise indicated.

The flapper of the 3583 Series valve stem positiontransmitter is always positioned in the reverse-actingquadrant as shown in figure 19. To reverse thesignal, reverse the cam as follows:

1. Unhook the spring (key 38), and remove the cambolt (key 6), cam (key 4), and spring retainer bracket(key 43).

2. Screw the locking nut (key 45) all the way ontothe cam bolt.

Note

If the arrow stamped on the cam pointstoward the nozzle, output pressureincreases with downward stemmovement. If the arrow points downaway from the nozzle, output pressuredecreases with downward stemmovement.

3. Reverse the cam (key 4) from its original position.

Attach the cam and spring retainer bracket with thecam bolt. Tighten the cam bolt to secure the cam.Then tighten the locking nut against the springretainer bracket.

4. Hook the spring into the spring retainer bracket.

5. After reversing the cam, perform the calibrationprocedures in the calibration of valve positioners andtransmitters section.

NOTE:ALIGN INDEX MARKS AS SHOWN FOR MID-TRAVEL POSITION.

A2452-3 / IL

Figure 16. Rotary Shaft Arm 0-Degree and Case Index Marks,Location and Alignment

The purpose of beam alignment is to ensure thecorrect mechanical position of parts so the valvepositioner can be calibrated. Provide the appropriatesupply pressure. Also, provide an input signal to thepositioner which can be manually set at the midpointof the desired input signal range.

Refer to figure 15 for parts locations. Refer to figure20 for key number locations unless otherwiseindicated. Position the flapper assembly by hand todifferent settings on the beam assembly or by usinga screwdriver in the slot of the flapper settingadjustment.

To level the beam, proceed as follows:

Note

In the following steps, if the requiredrotary shaft arm position cannot beattained when adjusting a pivot point,adjust one of the other pivot pointsslightly. Then, repeat the original pivotadjustment. Continue this processuntil the required arm position can be

attained.1. Stroke the actuator to its mid-travel position witha handwheel or a manual loader. Refer to figures 3and 6. Lift the rotary shaft arm (key 2) so that the0-degree index marks on the rotary shaft arm alignwith the case index marks as shown in figure 6.Then, position the travel pin (key 60) so that it isperpendicular to the arm and aligns with theappropriate total actuator travel index mark on therotary shaft arm. Tighten the locking nut (key 62).

Note

Valve stem travels less than 29 mm(1.125 inches) require that the travelpin be set at the 1-1/8 inches travelindex mark on the rotary shaft arm.

2. Loosen the nozzle locknut and turn the nozzleclockwise to its lowest position. Then screw thenozzle out (counterclockwise) approximately 2 turnsand tighten the locknut.

Note

For proper operation, the flapper mustapproach the nozzle squarely. Inspectthe nozzle/flapper alignment. Be surethe flapper is not loose, bent, ortwisted.

3. Remove any loading pressure and/or disengageany handwheel used to position the actuator.Connect the necessary tubing from the valvepositioner output to the actuator pressureconnection.

4. Connect the input to the valve positioner and setthe input signal value at midrange. For example, fora 3582 Series valve positioner with a 0.2 to 1.0 bar(3 to 15 psig) input signal range, set the input signalat 0.6 bar (9 psig). Then apply supply pressure tothe valve positioner.

5. Move the flapper assembly to zero on the beamscale. The 0-degree index marks on the rotary shaftarm should align with the case index marks asshown in figure 16. If not, loosen the followerassembly screw locknut and adjust the followerassembly screw until the 0-degree index marks onthe rotary shaft arm align with the case index marks.Tighten the locknut.

6. Move the flapper assembly to position 10 on thedirect-acting side of the beam scale. The 0-degreeindex marks on the rotary shaft arm should align withthe case index marks as shown in figure 16. If not,loosen the bellows assembly locknut and adjust thebellows pivot pin until the 0-degree index marks on

the rotary shaft arm align with the case index marks.Tighten the locknut.

7. Move the flapper assembly to the left to position10 on the reverse-acting side of the beam. The0-degree index marks on the rotary shaft arm shouldalign with the case index marks as shown in figure16. If not, loosen the beam pivot pin locknut andadjust the beam pivot pin until the 0-degree indexmarks on the rotary shaft arm align with the caseindex marks. Tighten the locknut.

8. Repeat steps 5, 6, and 7 to optimize alignment.Recheck to make sure the flapper approaches thenozzle squarely. If it does not, adjust the nozzle andre-level the beam. After alignment, the valvepositioner is ready for calibration.

Calibration1. Shut off the supply pressure to the valvepositioner. Connect or reconnect the necessarytubing from the valve positioner output to theactuator supply connection. Connect the input to thevalve positioner and set the input signal value atmidrange.

2. Move the flapper assembly to approximatelyposition 6 in the proper operating quadrant of thebeam (direct or reverse acting), and apply supplypressure to the valve positioner. The 0 degree indexmarks on the rotary shaft arm should align with thecase index marks as shown in figure 16 and theactuator should be at its midtravel position. If not,first check for loose linkage or improper caminstallation. A minor nozzle height adjustment mightbe necessary to make the desired input signal valuecorrespond to the starting point of travel.

3. Apply an input signal equal to the low value of theinput signal range. For example, for a 3582 Seriesvalve positioner with a 0.2 to 1.0 bar (3 to 15 psig)input signal range, set the input signal at 0.2 bar (3psig). Loosen the nozzle locknut and adjust thenozzle until the actuator moves to the proper end of its travel. Changing the nozzle position is intendedonly as a means of zero trim adjustment. Whenevernozzle position is changed, the zero reference point

is changed.4. Apply an input signal equal to the high value of the input signal range and observe the actuator stemtravel. If the stem travel is short of its expectedrange, increase the travel by moving the flapperassembly to a higher number on the beam. If thedesired stem travel occurs before the input signalreaches the high value of the input signal range,decrease the travel by moving the flapper assemblytoward a lower number on the beam.

Figure 17. Schematic Illustration of 3582 Series Positioner

5. Repeat steps 3 and 4 until the correct travel isachieved. Each time the flapper position is changedin step 4, repeat step 3 to provide proper zero.

Moving the flapper assembly toward zero on thebeam scale decreases stem travel. Table 10 lists theminimum stem travel available for different travel pinsettings. For example, with a travel pin setting of 2the minimum stem travel possible, for the full input

signal range, would be 11 mm (0.4375 inch).

Note

The positioner will fully vent orpressurize the actuator to supplypressure at the ends of actuator travelwhen the positioner is calibratedcorrectly. Failure to properly calibratethe positioner may result in reducedseat loading.

Principle of Operation

3582 Series Valve PositionersThe 3582 Series (the Type 3582, 3582NS andTypes 3582A, C, D, and G pneumatic valvepositioners) accept a pneumatic input signal from acontrol device. Figure 17 is an operational schematicfor a direct-acting pneumatic valve positioner.


26/48



26

As shown in figure 17, in a diaphragm-actuated,sliding stem control valve package with a 3582Series valve positioner, supply pressure isconnected to the Type 83L relay. A fixed restrictionin the relay limits flow to the nozzle so that when theflapper is not restricting the nozzle, air can bleed outfaster than it is being supplied.

The input signal from the control device is connectedto the bellows. When the input signal increases, thebellows expands and moves the beam. The beampivots about the input axis moving the flapper closerto the nozzle. The nozzle pressure increases and,through relay action, increases the output pressureto the actuator. The increased output pressure to theactuator causes the actuator stem to movedownward. Stem movement is fed back to the beamby means of a cam. As the cam rotates, the beam

pivots about the feedback axis to move the flapperslightly away from the nozzle. The nozzle pressuredecreases and reduces the output pressure to theactuator. Stem movement continues, backing theflapper away from the nozzle, until equilibrium isreached.

When the input signal decreases, the bellowscontracts (aided by an internal range spring) and thebeam pivots about the input axis to move the flapperaway from the nozzle. Nozzle pressure decreasesand the relay permits the release of diaphragmcasing pressure to atmosphere. The actuator stemmoves upward. Through the cam, stem movement isfed back to the beam to reposition the flapper closerto the nozzle. When equilibrium conditions areobtained, stem movement stops and the flapper ispositioned to prevent any further decrease indiaphragm case pressure.

The principle of operation for reverse acting units issimilar except that as the input signal increases, thediaphragm casing pressure is decreased.Conversely, a decreasing input signal causes anincrease in the pressure to the diaphragm casing.

Type 3582i Valve Positioner As shown in figure 18, the Type 3582ielectro-pneumatic valve positioner has a Type 582ielectro-pneumatic converter attached to the valvepositioner. The 582i contains an I/P module whichprovides a pneumatic output proportional to a dccurrent input signal. The dc current input operatescoils in a force balanced beam system which in turn,control bleed air through an integral nozzle/flapper

A4818-2/IL

arrangement. The nozzle pressure provides thepneumatic input signal pressure used by thepneumatic valve positioner.

3583 Series Valve Stem PositionTransmitters3583 Series (Type 3583, 3583C) pneumatic valvestem position transmitters are mechanically linked tothe valve stem in a diaphragm-actuated, sliding-stemcontrol valve package. A change in the position of the valve stem changes the output pressureproduced by the position transmitter. This signal isthen piped to a reporting or recording device toindicate valve stem position.

The action of a valve stem position transmitter canbe changed by reversing the internal cam. The valvestem position transmitter cam is supplied with anarrow stamped on one side. The cam can bepositioned to obtain either increasing or decreasingoutput pressure with downward stem motion. If thecam arrow points toward the nozzle, the outputpressure increases; if the cam points away, theoutput pressure decreases with downward stemmotion.

Figure 19 depicts a diaphragm actuator whichproduces downward stem motion for increasingactuator pressure. For a stem position transmitter,the flapper assembly is always positioned in thereverse-acting quadrant of the beam. Supplypressure is connected to the Type 83L relay. A fixedrestriction in the relay limits flow to the nozzle so thatwhen the flapper is not restricting the nozzle, air canbleed out faster than it is being supplied.

As the pressure to the diaphragm actuatorincreases, the valve stem moves downward, causingthe internal cam to rotate. Cam rotation causes thebeam to pivot about the input axis moving theflapper closer to the nozzle. The nozzle pressure

increases which, through relay action, increases theoutput pressure.

The output pressure is also connected to thebellows. As the output pressure increases, thebellows expands, causing the beam to pivot aboutthe feedback axis moving the flapper slightly awayfrom the nozzle until equilibrium is reached. Theposition transmitter output pressure is nowproportional to the valve stem position.

As the pressure to the diaphragm actuatordecreases, the valve stem moves upward, causingthe internal cam to rotate. Cam rotation causes thebeam to pivot about the input axis moving theflapper away from the nozzle. The nozzle pressuredecreases which, through relay action, decreasesthe output pressure. The bellows contracts, causingthe beam to pivot about the feedback axis andmoving the flapper closer to the nozzle untilequilibrium is reached. The position transmitteroutput pressure is again proportional to the valvestem position.

Maintenance

WARNING

Avoid personal injury from suddenrelease of process pressure. Beforeperforming any maintenanceoperations:

D Always wear protective clothing,gloves, and eyewear when performingany maintenance operations.

D Disconnect any operating linesproviding air pressure, or a controlsignal to the actuator. Be sure theactuator cannot suddenly open orclose the valve.
