Bermad WW718-03-B Sigma EN ES Electronic Control Valve



Bermad WW718-03-B Sigma EN ES Electronic Control Valve

The Bermad 718-03-B is an electronic control valve that combines the advantages of an excellent modulating, line pressure driven, hydraulic control valve with those of electronic control. In response to signals from the electronic controller (or PLC), the valve changes its opening position per preset values programmed into the controller.The valve is double chamber actuated and is powered to fully open and close even at very low pressure. Both the valve’s opening and closing speeds are controllable and on-site adjustable. 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.
