    Wiring diagram

    CONTROL CIRCUIT
    electric actuatorOrdinary switch type (A type)
    The valve can be opened or closed through the switch   circuit, and a set of activeposition models indicating   that the valve is fully open and fully closed are output.

     

     

    electric actuatorPassive contact type(B type)
    Realize valve opening or closing operation through switch circuit, and output a setof passive position models indicating that the valve is fully open and fully closed

     

     

    electric actuatorOpening signal type(C type)
    Open or close the valve through the switch circuit, and output a resistance signalcorresponding to the opening position

     

     

     

    electric actuatorWith position transmitter (D type)
    Realize valve opening or closing operation through switch circuit,and outputcurrent signal corresponding tovalve opening and closing angle at the same time.

     

     

    electric actuatorlntelligent adjustment type(E type)
    Control the opening and closing angle of the valve through the standard signalinput by an extenal computer or  indus trial instrument, and synchronously outputthe correspond ing standard signal

     

     

    electric actuatorDC switch type(F type)
    By switching the positive and negative poles of the external DC power supply, thevalve can be“opened”and“closed”,and a set of passive contact signalsin dicating that the’valve is fully open or ciosed can be output

     

     

    electric actuatorThree-phase switch type(G type)
    The valve is opened or closed through the switch circuit, and a set of active positionsignals indicating the valve is fully open and fully closed is output.

     

     

    electric actuatorThree-phase passive contact type(H type)
    Realize valve opening or closing operation through switch circuit,and output a setof passive position signals indicating that the valve is fully open and fully closed.
