ZWZP Electric High Temperature Steam Globe Control Valve
Electric High Temperature Steam Globe Control Valve
This high temperature control valve is composed of an electric actuator and a high precision low flow resistance regulating valve body. The electric high-temperature steam globe control valve has the advantages of tight closing, compact structure, light weight and convenient maintenance.The BCST electric high temperature control valve is equipped with a 3810 series (or PSL series) electric actuator and a small precision regulating valve body. It accepts a standard signal of 4-20 mA or 1-5 V·DC to convert the current signal into a corresponding linear displacement.The electric high temperature control valve adopts a balanced valve plug structure, which is widely used in the occasions where the flow rate is large, the temperature is high, and the leakage amount is not strict.
