PRODUCT OVERVIEW

Pneumatic wafer type hard seal butterfly valve adopts precise J-shaped elastic seal ring and three eccentric multi-level metal hard seal structure. It is widely used in metallurgical, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ for regulating flow and carrying off fluid. The valve adopts three eccentric structure. The sealing surfaces of valve seat and disc plate are made of stainless steel with different hardness. It has good corrosion resistance and long service life. The valve has two-way sealing function.

PRODUCT FEATURES

1. The valve adopts a three eccentric sealing structure, with almost no wear between the valve seat and the butterfly plate, and has the sealing function of closing and tightening.

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life under low and high temperature.

3. The sealing surface of butterfly plate adopts surfacing cobalt based cemented carbide, which has wear resistance and long service life.

4. The large-size butterfly plate adopts quilted frame structure, with high strength, large overflow area and small flow resistance.

5. The valve has a two-way sealing function. It can be installed in any direction without the restriction of medium flow direction and the influence of spatial position.

6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °), which is convenient for users.
