A user-friendly valve train unit designed by Air Liquide,
the GAS CONTROL CABINET is suitable for pump-
based gas injectors to control your motors and gas-
dosing systems.
It easily regulates the concentration of a dissolved gas
into a liquid. The required sensor sends a signal to a
motor valve that supplies the proper gas quantity. In the
event of a sensor failure, a fixed flow ensures continuous
operation in manual mode.
The amount of gas is measured by a thermal flow
meter, providing you with high accuracy thanks to its
low sensitivity to pressure and temperature variations.
A check valve and an air valve at the outlet are used to
prevent backflow and to interrupt the gas supply when
the injector pump is off or on idle. Two control loops – one
on the dissolved gas concentration and one on the gas
flow – provide a truly effective regulation.
All process information for operation and maintenance
related to power (voltage, consumption, pump, relay
status), gas (pressure, flow, dissolved concentration), and
alarms (power, pressure, flow transmitters) can be sent to
the operator’s display via common data-transfer modes.
