Pneumatic hard seal butterfly valve,Pneumatic hard seal butterfly valve,Hard seal butterfly valve

Product characteristics

1, the valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with the tighter the sealing function.

2, the sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic seal, regardless of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics.

3, the sealing surface of the butterfly plate adopts surfacing welding cobalt-based cemented carbide, the sealing surface is wear-resistant and has long service life.

4, large specifications of the plate quilted structure, high strength, large flow area, small flow resistance.

5, the valve has a bidirectional sealing function, installation is not limited by the flow of the medium, is not affected by the spatial position, can be installed in any direction.

6, the drive device can be installed in multiple stations (rotation 90° or 180°), easy to use

Pneumatic clamping butterfly valve with precision J-shaped elastic seal ring and three eccentric multi-layer metal hard seal structure, is widely used in the medium temperature ≤425℃ metallurgy, electric power, petrochemical industry and water supply and drainage and municipal construction and other industrial pipelines, for regulating flow and load body use. The valve adopts three eccentric structure, the valve seat and plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the valve has a two-way sealing function.
