Pressure Relief/Sustaining Valve with Solenoid Control IR-WW-730-55

The Model 730-55 Pressure Relief/Sustaining Valve
with Solenoid Control is a hydraulically operated,
diaphragm actuated control valve that sustains minimum
pre-set, upstream (back) pressure regardless of
fluctuating flow or varying downstream pressure.
It also either opens or closes in response to an
electric signal. When installed as a circulation valve,
the Model 730-55 relieves excessive line pressure
when above maximum pre-set.

Line pressure driven – Independent operation

Solenoid controlled
