Regulating pneumatic butterfly valve

Overview:

The regulating pneumatic butterfly valve is composed of a valve stem, valve body, valve plate, valve seat, pneumatic actuator and positioner, etc. When the pneumatic actuator receives a signal from the control system, it transmits power to the valve stem through compressed air or other gases, causing the valve plate to rotate and thereby changing the on-off state of the valve. The soft sealing design and structure of the valve seat enable the valve to have good sealing performance in the closed state, and it is widely used in the fluid control system in the industrial production process.
