Bermad WW-710-B Sigma Double Chambered Large Metal EN ES Powered Hydraulic Solenoid Valve (AS5081 & WaterMark) 

The Bermad 710-B is a double chambered, hydraulically operated, solenoid-controlled valve that either opens fully, regardless of valve differential pressure, or shuts off in response to electric signal. This valve is especially useful in very low-pressure applications and in corrosive fluid systems that are controlled by external fresh water or compressed air. Normally open (NO), normally closed (NC) or LATCH models are available. BERMAD 700 SIGMA EN/ES series valves are hydraulic, oblique pattern, globe valves with a raised seat assembly and double chamber unitized actuator, that can be disassembled from the body as a separate integral unit.

The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential pressure applications. The valves are available in the standard configuration or with an Independent Check Feature code “2S”. The 700 SIGMA EN/ES Valves operate under difficult operation conditions with minimal cavitation and noise. They meet size and dimensions requirements of various standards.
