SINGLE STAGE GAS VALVES
DESCRIPTION OF HOW THE VALVE OPERATES
Single-stage valves
When the valve receives the signal to open, the pump cuts in and the magnetic valve closes. The pump transfers the
oil from under the piston to above it, forcing the piston downward, which compresses the closure return spring with
the rod and plate. The valve remains in the open position while the pump and magnetic valve remain powered.
When the unit receives the signal to close (or if power supply is cut off) the pump shuts down, the magnetic valve
opens decompressing the chamber above the piston. The plate is closed both by the return spring and by gas
pressure.
The flow rate for this valve is calculated to ensure full closure in less than one second.
This type of valve cannot regulate the gas flow rate
(closure/opening).
Screw “D” on terminal “IV” sets the “clean contact”
position which can be used for an outside signal.
A = Driver identification plate
B = Flow direction indicator
C = Valve body identification plate
