The main features of pneumatic butterfly valve are
1. Exquisite and light, very easy to remove and repair, can be installed anywhere.
2. The structure is simple and compact, the actual working torque is small, and the 90 ° rotation can quickly open.
3. The total flow characteristics tend to be parallel, and the regulation characteristics are good.
4. The connection between the butterfly plate and the valve stem adopts a non separating pin structure, eliminating potential internal leakage points.
5. The inner hole of the butterfly plate is designed into a curved shape, which improves the density 6. The sealing gasket is detachable and more reliable than the double sealing gasket.
7. Paint the butterfly plate according to customer requirements, such as polyester or PTFE.
8. The valve can be designed as loose flange and a pair of clamping connections.
9. The driving mode can be manual, electric or pneumatic. Pneumatic butterfly valve is suitable for water supply and drainage, waste water, food, heat supply, natural gas, ships, hydropower engineering, metallurgical industry, energy supply and light industry and other manufacturing industries. It is very suitable for the places where double seals and oil circuit boards are prone to rust. Please adjust the total flow and trapped substances.
The sealing structure of pneumatic butterfly valve is composed of PTFE and synthetic rubber, forming a composite seat. Its characteristics depend on the ductility of the valve. It is still produced and used by synthetic rubber. PTFE has low friction resistance and is not easy to damage and embrittlement. The service life of the butterfly valve is long enough. The basic sealing principle and structural characteristics of pneumatic butterfly valves are the same as those of general center line butterfly valves. The sealing performance extends the service life of the gate valve. It remains leak free after opening and closing under pressure for about 50000 times.
