Cast iron electric diaphragm control valve has simple structure, low flowing resistance. Compared with other valves having the same caliber, the flowing resistance of electric diaphragm control valve is lower. The valve can adjust the medium having high viscosity or suspended particles. Based on different materials of diaphragm (rubber or PTFE), the valve is applicable for strong alkaline or strong corrosive medium. The valve is equipped with electric actuator having servo system. Only using input signal or single electric source can control the pressure, flow, temperature, level of medium without using amplifier.
