  • ZRHJ electric angle control valve Feature

    ZRHJ electric angle control valve is specially designed for the medium which is high viscosity, easy to crystallize, containing suspended particles and 90 degree angle area. Electric angle control valve can choose single seat or balanced sleeve disc,which can be used on some high pressure differential or multistage adjustment.
    ZRHJ electric control valve main advantage as below:
    01.Electric Angle Control Valve is used for large viscosity, easy crystallization,and easy coagulation situation, etc.
    02.Actuator of  Electric angle control valve  adopts multi-spring circular equal layout, using high strength rubber diaphragm actuation parts, with small structure and large output force
    03. Small pressure differential loss, accurate flow control
    04.No dead corner in the Electric angle control valve, easy to clean, also applicable for food industry
