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

  • Low power consumption
  • Wide ranges of pressures and voltages
  • Normally Open, Normally Closed, or Last Position

Balanced seal disk – High relief flow capacity

In-line serviceable – Easy maintenance

Double chamber design

  • Moderated valve reaction
  • Protected diaphragm

Flexible design – Easy addition of features

Variety of accessories – Perfect mission matching

“Y” or angle, wide body – Minimized pressure loss
