Bermad brand electronic control valve model 718-03

Electronic control valve that combines the advantages of an excellent hydraulic modulating control valve, driven by line pressure, with those of electronic control valves. In response to signals from the electronic controller, the valve changes its opening position according to preset values programmed into the controller. The valve's closing and opening speeds are controllable and can be adjusted on-site. BERMAD's SIGMA 700 EN/ES series valves are hydraulically operated, oblique-shaped globe valves in which the raised seat assembly and the single-piece dual-chamber actuator can be removed from the body as an integral part. The hydrodynamic body has been designed to provide an unobstructed flow path, with excellent modulation capability and is highly effective for applications with large pressure differentials. These valves are available in the standard configuration or with an independent check function, code "2S". Sigma 700 EN/ES valves operate under harsh conditions with minimal risk of cavitation and no annoying noise. They meet the size and dimension requirements of various regulations.
