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

 DOWNLOAD PRODUCT BROCHURE

The Bermad WW-730-55 is a high-performance, hydraulically operated, diaphragm-actuated control valve designed to sustain a minimum preset upstream (back) pressure and to relieve excess line pressure when it rises above the maximum allowable level. The integrated solenoid allows remote electrical control, enabling the valve to open or close in response to system commands.

Engineered for high-pressure waterworks and pumping systems, the 730-55 functions as both a pressure sustaining and pressure relief valve, with solenoid-activated control that supports multiple modes – Normally Open (NO), Normally Closed (NC), or Last Position (LP).

The valve’s double-chamber design ensures moderated response and enhanced stability, while its balanced seal disc enables high relief flow capacity. Designed with a full-bore Y- or angle-body, the WW-730-55 minimizes head loss and turbulence. Its stainless steel raised seat resists cavitation damage in demanding applications.
