Electric High Temperature Steam Globe Control Valve

 

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.
