Surge anticipator/ pressure relief valve

Product overview
Designed to protect pumping stations against excess pressure. Senses low pressure condition that precedes high pressure. Relieves high pressure build-up and protects system from over pressure condition.
The valve shall open on a low or high pressure wave. The valve is equipped with two pilots in parallel. The low pressure pilot, adjusted below normal system operating pressure, sends the valve toward open position adjustable
by flow limiter during the low pressure period created by the pumps shut-off. The relief pilot, set above the normal
system operating pressure, opens the valve and maintain the valve in open position during the over pressure period. The valve is normally mounted in a by-pass of the main pipe line to discharge the over flow to the atmosphere or into the suction tank.

Additional features
– Solenoid on-off control function. A remote control switch on / off the valve;
