Diaphragm valve WW-790-M

hydraulicfor controladjustment

Hydraulically operated, diaphragm actuated, burst control valve that senses flow levels. When it senses flow in excess of settings, it shuts off and locks drip tight until manually reset. As long as flow is lower than settings, the valve remains fully open, minimizing head loss. A flow stem enables limiting valve opening stroke, precisely adjusting the required flow through the valve. 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.
