Precise Intelligent Valve Positioner Single Phase Three Phase Switch on/off Electric Actuator

Single-phase three phase Electric Actuator Intelligent Valve Positioner

Product type
Standard switch type(B)
Valves ON/OFF is conducted by switch circuit with outputting active contact signal which can show a fully open or fully close state of the valves.
Passive contact type(S)
Valves ON/OFF is conducted by switch circuit with outputting passive contact signal which can show a fully open or fully close state of the valves.
Position signal type(K)
Valves ON/OFF is conducted by switch circuit with outputting a relative group of open or close degree current signals
Opening degree signal type(R)
The opening angle of valves is controlled by switch circuit,with potentiometer outputting resistance signal corresponding valves opening angle.
Modulating type(A)
Intelligent regulation and control are conducted by receiving the standard signal4-20mA DC,0-10V,DC or 1-5V.DC outputted by the computers of instruments standard feedback signal 4-20mA DC is also outputted.
