Electrically actuated butterfly valves allow the position of the butterfly valve to be automatically (or motorized) controlled remotely whereas manually operated butterfly valves require human intervention at the physical location of the valve. Compared with the more traditional flanged gate valves, an actuated butterfly valve is lighter in weight making it easier to install, and offers more favorable pricing.
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.
