Main features of
pneumatic butterfly valve
1. The flow characteristics tend to be straight, and the regulation performance is good.
2. The valve can be designed as flange connection and wafer connection.
3. Small and light, easy to disassemble and repair, and can be installed in any position.
Fourth, the butterfly plate can be sprayed with a coating layer, such as nylon or PTFE, according to user requirements.
5. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
Sixth, the seal can be replaced, and the seal is reliable to achieve two-way sealing.
7. The driving mode can be manual, electric or pneumatic.
8. The structure is simple and compact, the operating torque is small, and the 90° turn to open quickly.
9. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage when opening and closing more than 50,000 times under pressure.
