What is the difference between pneumatic flange butterfly valve and manual butterfly valve? Pneumatic butterfly valve uses compressed air as the power source, air cylinder as the actuator, and electric/pneumatic valve positioner, converter, solenoid valve, retaining valve and other accessories to drive the valve. (relative movement of valve core and valve seat) to realize on-off or proportional regulation, receive control signal: 4-20mA current signal and convert electrical signal into pressure signal (completed by positioner or solenoid valve) to regulate various process parameters such as flow, pressure and temperature of pipeline medium.
