Bermad WW-730-55 Large Metal Hydraulic Pressure Relief/Sustaining Valve with Solenoid Control (AS5081/WaterMark)

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.

• Prioritizing pressure zones
• Pump overload & cavitation protection
• Backup for reservoir supply valves
• Safeguarding pump minimum flow
• Switching between pressure regimes
