butterfly valve series-九游官网下载

product overview

the worm gear flange metal seat butterfly valve adopts a precise j-shaped elastic seal ring and a three eccentric multi-layer metal hard seal structure. it is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃, as a flow regulator and a flow carrier. the valve adopts three eccentric structure, and the sealing surfaces of the valve seat and the disc plate are made of stainless steel with different hardness, which has good corrosion resistance and long service life.

structural features

1. the valve adopts a three eccentric sealing structure, and the valve seat and the butterfly plate are almost free of wear, with a tighter sealing function.

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

3. the sealing surface of the disc plate is overlaid with cobalt based cemented carbide. the sealing surface is abrasion resistant and has a long service life.

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

5. the valve has a two-way sealing function. it can be installed in any direction without being restricted by the flow direction of the medium or affected by the space position.

6. the driving device can be installed at multiple stations (rotated by 90 ° or 180 °), which is convenient for users.
