The main features of the flange butterfly valve
1. Compact and lightweight, 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 opening of the 90 DEG rotation is rapid.
3. Flow characteristics tending to straight line, good adjustment performance.
4. Disc stem connection with the use of non pin structure, overcome the possible internal leak.
5. The outer circle of the butterfly plate adopts the spherical surface shape, which improves the sealing performance and prolongs the service life of the valve, and the pressure opening and closing is still more than 50 thousand times.
6. The sealing element can be replaced, and the sealing is reliable.
7. Butterfly plate can be sprayed according to user requirements, such as nylon or Teflon coating.
8. The valve can be designed as a flange connection and a clamp connection.
9. Drive mode can choose manual, electric or pneumatic.
Flange butterfly valve is suitable for temperature are less than 120 or less than 150 DEG C, nominal pressure is less than 1.6MPa water supply and drainage, sewage, food, heating, gas, shipbuilding, hydropower, metallurgy, energy systems and textile industries, especially suitable for bidirectional seal and body corrosion situation, adjust the flux and closure of media.
