Product description

Pneumatic rubber seated butterfly valve is also a concentric soft-seal butterfly valve, which can be used not only to cut off the medium, but also to adjust the flow of the medium.

Application

Pneumatic soft sealing butterfly valve is suitable for temperature ≤120℃ or ≤150℃, nominal pressure ≤1.6MPa water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy system and light textile industries, especially suitable for leakage For high requirements and corrosive occasions, it is used as a flow adjustment and interception medium.

Feature

1. Small and light, easy to disassemble and maintain, and can be installed in any position.
2. The structure is simple and compact, the operating torque is small, and the 90° rotation can be opened quickly.
3. The flow characteristic is straight line, and the adjustment performance is good.
4. The connection between the butterfly plate and the valve stem adopts a pin-free structure, which overcomes the possible internal leakage point.
5. 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 for more than 50,000 times of opening and closing under pressure.
6. The seals can be replaced, and the sealing is reliable and can achieve bidirectional sealing.
7. The butterfly plate can be sprayed with coating according to user requirements, such as nylon or PTFE.
8. Pneumatic soft sealing butterfly valve can be designed as flange connection and wafer connection.
