RV ZJHF(H) Electric Three-way Diverging (Converging) Control Valve RV ZJHF(H) Electric Three-way Diverging (Converging) Control Valve，a three-way diverging (converging) valve is equipped with a PS series actuating unit;a servo system is arranged is arranged inside an electric actuator,which does not need to be additionally equipped with a servo amplifier and can control moving and rotating through input control signal (4~20mADC or 1-5 VDC) single-phase power source,thus realizing the control of patameters like pressure,flow,temperature,liquid level,etc.The valve adopts a balanced valve plug structure,has the characteristics of good plug stability,no eas vibratoin,low noise,large allowable using pressure difference,simple connecion,etc,and can be broadly applied in to the industrial automatic control systems of industries like electric power,metallurgy,oil,chemical industry,light industry,environmental protection,etc,which have large flow coeffcients and strict requirements on leakage volume.
