The gas feed systemsV10k automatic and manual
control is the proven gas feed technology from
Wallace & Tiernan for capacities up to 15 kg/h
combining a standardised flexible design with
user-selectable configurations. The V10k gas
feeders operate according the indirect procedure
i.e. operating under a vacuum that is produced at
the injector where the metered gas (e.g. chlorine
gas) is dissolved in the operating water and the
resultant solution is discharged to the point of
application. Gas flow control is achieved by the
proven Wallace & Tiernan V-notch ensuring the
well-known accuracy and repeatability.
METHOD OF OPERATION
The V10k gas feed systems operate under a
vacuum that is produced at the injector and
transmitted through the control unit to the pressure/
vacuum regulating valve on the gas supply source.
This diaphragm-operated valve is opened by the
vacuum and allows the gas to flow to the control
unit where it passes through the rotameter and the
V-notch orifice. On the rotameter the gas flow rate
is measured and indicated. Downstream of the
V-notch orifice the gas passes the differential
regulating valve which maintains a consistent feed
rate regardless of changes in the operating vacuum.
At the injector, the metered gas is dissolved in the
operating water stream and discharged as solution
to the point of application.
Highest Safety by Remote Vacuum
The remote vacuum principle (vacuum from the gas
supply containers up to the injector) is the basic
technology of this design. There are no gas lines
under pressure. If any part after the supply container
gets broken, no gas can leak out, but air will leak in.
Therefore the remote vacuum technology stands for
the highest safety level in gas feed systems.
V-notch for Precise Gas Flow Control
The V-notch control orifice, field proven in hundreds
of thousands of installations around the world,
provides reliable, consistent gas feed at any
capacity. It consists of a precision-grooved plug that
slides through an annular seat. Any position of the
plug in the seat results in a specific orifice size and a
corresponding feed rate. This results in accurate gas
flow control and excellent repeatability.
Due to their size and the configuration of the orifice,
theV10k systems are resistant against fouling from
contaminants in the gas supply.
Control of the gas feed rate for the V10k manual
control gas feed system is achieved manually by
turning the adjustment knob, for theV10k automatic
control gas feed system either manually or auto-
matically via an electric positioner.
Electric Positioner for Automatic control
For automatic control, the V-notch plug is moved
depending on the application requirements:
Manual override is achieved by simply pulling the
knob to disengage the drive motor
3 sets of volt-free contacts for system control:
manual override
MAX position
MIN position
Feedback potentiometer for precise operation
with the SCU or PCU-fuzzycontrollers
4 20 mA actuator control (optional)
Simple ratio control
Feed rate adjustment by means of a dosing factor
Connection to SPS control systems
