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.
