Product Description
Pneumatic wafer type hard seal butterfly valve adopts precise J-shaped elastic sealing ring and three eccentric multi-level metal hard seal structure, and is widely used in industrial pipelines with medium temperature ≤ 425 ℃, such as metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction, etc., for adjusting flow rate and carrying off fluid.
Pneumatic wafer type butterfly valve
Pneumatic wafer type hard seal butterfly valve characteristics;
1, pneumatic wafer type hard seal butterfly valve adopts three eccentric sealing structure, valve seat and butterfly plate almost no wear, with the view of the more tight sealing function.
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 conditions.
3. The sealing surface of the disc plate adopts surfacing cobalt-based hard alloy, which is wear-resistant and has long service life.
4. Large size butterfly plate adopts quilted frame structure, high strength, large flow area and small flow resistance.
5, the valve has a two-way sealing function, the installation is not restricted by the flow of the medium, nor is it affected by the space position, can be installed in any direction.
6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °), which is convenient for users to use.
Pneumatic wafer type hard seal butterfly valve adopts three eccentric structure, valve seat and disc sealing surface are made of different hardness and stainless steel, has good corrosion resistance, long service life.
Gas butterfly valve according to the different forms of sealing, mainly divided into hard seal gas butterfly valve and rubber soft seal butterfly valve,
