The pneumatic flanged hard-sealed butterfly valve uses a precise U-shaped elastic sealing ring and a three-off-center multi-layer metal hard sealing structure. It is widely used in industries such as metallurgy, power, petrochemical, and municipal construction for media with temperatures ≤425°C, for regulating flow and cutting off the flow. This valve uses a three-off-center structure, with both the valve seat and disc sealing surfaces made of different hardness stainless steel, offering good corrosion resistance and a long service life. This valve has bidirectional sealing capabilities and meets the national GB/T 13927-92 valve pressure test standards.

Main Standards

Product Features

1. This valve uses a soft sealing structure, with tighter sealing as it closes, providing reliable sealing performance.
2. The sealing auxiliary material uses Viton oil-resistant rubber, extending the service life.
3. The rubber sealing ring can be located on the valve body or the disc, suitable for different media characteristics, offering users options.
4. The disc uses a frame structure, high strength, large flow area, and low resistance.
5. The whole body is coated, effectively preventing rust, and can be used with different media by simply replacing the valve seat sealing material.
6. This valve has bidirectional sealing capabilities, not affected by the direction of the medium flow during installation, and can be installed in any direction.
7. The unique structure of this valve makes it flexible to operate, labor-saving, and convenient.
