First, what is the pneumatic switch butterfly valve? The pneumatic switch butterfly valve is synthesized through the butterfly valve body and the pneumatic actuator. The power of the pneumatic switch butterfly valve is from the compressed air. The valve core is driven by the valve stem to rotate 90 degrees in the valve body, so that the action process from full opening to full closing can be carried out. According to the sealing performance, the pneumatic switch butterfly valve can be divided into soft seal and metal seal. The pneumatic switch butterfly valve has the advantages of easy maintenance, easy installation, strong adaptability, good sealing performance, reliable operation and compact structure. 　　　　

Regulating valves are mainly used to regulate the flow and pressure of media. Including regulating valve, throttle valve, pressure reducing valve, etc.
