Toyo Lead-Free Copper Alloy MUEN-KUN®

無鉛くん®

This globally patented lead-free copper alloyemploys bismuth and selenium instead of lead.This has met the world's most rigorouscriterion of a maximum of 0.01mg/liter of leadelution into drinking water, which came intoforce in Japan in April 2003.Remark:1) Some valves are lead-free surface treatedinstead.

2) Maximum allowable temperature:100ﾟC

Memory Stop Plate

A memory stop plate is attached to a leverhandle, and if it adjusts to the arbitrarydegrees of full opening beforehand, a ballvalve can be maintained at the samedegrees at any time.(Available for Fig. 5044E/5044EW/5026/5026W)

Locking Handle

With a locking device, lever handle can be fixed in full open or closed position.However, please purchase padlock andkey on your side (Fig. 5041A).

Toyo DZR brass (Dezincification Resistant brass)

Water pollution and employment of new piping material have amplified valve dezincification problems.

The copper alloy used in bronze valves contains zinc, tin, and lead with copper as a base. When bronze valves aresubjected to unfavorable service conditions, the zinc component contained in the copper alloy separates from thecopper base, and the metal corrodes. This is called dezincification.In case of bronze valve, the body, bonnet, and other cast bronze parts hardly corrode due to the small percent of zinccontained in the alloy. But brass valve parts such as stems, which contain 40% zinc, often corrodes due to extremedezincification.

The following factors cause dezincification. These factors are generally believed to occur together, rather thanindependently.1) Excessive aqueous solution in acidity.2) Warm water containing excessive free carbonic acid with high electric conductivity.3) High electric conductivity with excessive presence of chlorides and sulfides.4) Copper or vinyl chloride pipes.5) Excessive dissolved oxygen.

To struggle with dezincification corrosion, Toyo Valvedeveloped TOYO DZR brass as the stem material ofbronze/brass valves. Our test data show excellent corrosionresistance to be comparable to bronze continuous castingbars.TOYO bronze/brass valves have these DZR brass or bronzestems in standard specification, and offer longer service life.

■ Features●Toyo Nylon Lined Cast Iron Valves conform toJIS B2031.(Gate, Globe & Check Valves)

●There is no RUSTY-WATER accrual fromvalves since all surface of cast iron in directcontact with water is lined by Nylon 11.

●Nylon 11 can be used for a wide range of fluidwith having its corrosion resistance, sea water-proof nature & chemical resistance. (Pleaseconsult Toyo sales staff for details.

●Nylon 11 can be used in food industries.●Electrolytic corrosion does not occur, as Nylon11 is an insulator.

Special Valves■Valves with special functionsToyo Valve has much experience in not only standard products but also products with special functions. Please consultToyo sales staff or our local agent for details.

Limit switches

It is attached at open, closed or bothopen and closed positions for remotesurveillance.

Chain handle

Easy operation for a valve on elevated piping line.

Counter-weight check valve

By adjusting the counter-weight to the closed moment, water-hammer is restrained by quicker closing and excellent seatsealing capability is acquired. Balance of disc is maintained byadjusting the counter-weight to the open moment, the flowwith low pressure is facilitated and opening and closing disc ismade smooth.

Stem cap & cover

Protection of stem from dust, foreignobjects, etc. in order to avoid a pooroperation.

Moterized valve

Toyo has much and long experience tosupply motorized valves with highquality. On request, valves can beprovided with each maker's actuator likeLIMITORQUE, ROTORK, SEIBU, etc.

Toyo Dual Plate Check Valve● A water hammer is prevented (Silent Check Type)

By action of the coil spring built in a valve, plates are gently opened at the time of starting a pump or it closesquickly when a pump stops. For this reason, a water hammer is prevented and generating a shock pressure iscontrolled.

● It is compact.

A small and lightweight wafer body. As compared with a swing check, the face-to-face dimension is about 1/4 andthe weight is about 1/5. Piping work is easy, and attachment space for installation is also small.

●By-pass piping is unnecessary. (Fig. 365 and 440)

Since the by-pass valve is built in, the by-pass piping for discharge of the fluid in a pipe or priming when starting apump are unnecessary. It is a big merit on design and construction.

Comparison of Swing and Dual Plate

The conventional by pass piping line

Cv Value

The Cv value _ which is used by TOYO VALVE to indicate the capacity of a valve _ is a flow rate represented in terms ofU.S. gallons per minute when clear water at 60 F゚ flows through a valve, in which the differential pressure between itsoutlet and inlet is kept at 1 psi _ 6.89kPa.

The Cv value can be determined by experiment, and the relation between the Cv value and the flow rate or pressure drop,when the fluid is water.

In case of water, the pressure drop or the flow rate can be obtained by the following formulas.
