WW730-55 – Pressure Relief/Sustaining Valve with Solenoid Control AS5081 / WaterMark
Prioritizing pressure zones
Pump overload & cavitation protection
Backup for reservoir supply valves
Safeguarding pump minimum flow
Switching between pressure regimes
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, Model 730-55 relieves excessive line pressure when above maximum pre-set.
