Sanitary Butterfly Valve with Electric Acutator
Electric Actuator Type
* Standard switch type (B)
Valve ON/OFF is conducted by switch circuit with outputting active contact signal which can show a fully open or fully closed state of the valves.
*Passive contact type (S)
Valve ON/OFF is conducted by switch circuit with outputting passive contact signal which can show a fully open or fully closed state of the valves.
*Position signal type (K)
The opening or closing operation is realized by switching “open” or “close” the circuit, outputting a relative group 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 conduct by receiving the standard signal 4-20mA. DC, 0-10V. DC or 1-5V. DC outputted by the computers of instruments standard feedback signal 4-20mA. DC is also outputted.
