DESCRIPTION OF HOW THE VALVE OPERATES
Single-stage valves
When the valve receives the signal to open, the
p u m p c u t s i n a n d t h e m a g n e t i c v a l v e c l o s e s .
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 0.6 seconds.
This type of valve cannot regulate the gas flow rate (closure/
opening).
