Bermad WW770-U Sigma EN ES Flow Control Valve



Bermad WW770-U Sigma EN ES Flow Control Valve

The Bermad 770-U is a hydraulically operated flow control valve that maintains pre-set maximum flow, regardless of fluctuating demand or varying system pressure. 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.
