Pneumatic butterfly valve is often used as a shut-off valve in the application. It is used to open and close the valve through the rolling of the butterfly plate, and is often used in large and medium-diameter pipes. Common pneumatic valves include stainless steel pneumatic butterfly valves, hard sealing butterfly valves, soft sealing butterfly valves, carbon steel butterfly valves, etc. Each butterfly valve has its own characteristics, so you know a few about the characteristics of pneumatic butterfly valves?


1.The stainless steel pneumatic butterfly valve seal can be replaced and the seal is firmly connected to the two-way seal.


2. The flanged pneumatic butterfly valve is compact and simple, easy to disassemble and repair, and can be installed at any position.


3. The structure of the clamped pneumatic butterfly valve is simple and compact, the operating torque is small, and the 90° rotation is open and agile.


4. The soft-sealed pneumatic butterfly valve and the valve stem are connected with a pinless structure, which overcomes the possibility of internal leakage.


5. The outer ring of the hard-sealed pneumatic butterfly valve adopts the spherical shape, which improves the sealing function and prolongs the service life of the valve. It can still maintain zero leakage when the pressure is opened and closed more than 50,000 times.


6. The flow characteristics of the pneumatic butterfly valve tend to be straight, and the conditioning function is good.


7, pneumatic butterfly valve disc can be sprayed according to user requirements, such as nylon or polytetrafluoroethylene.


8. The hard seal butterfly valve can be planned to be flanged and the clamp is connected.
