Product description

       Worm gear flange hard sealing butterfly valve adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure. It is widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425℃ , Used for adjusting flow and carrying and breaking fluid. The valve adopts a triple eccentric structure, and the valve seat and the sealing surface of the disc plate are made of different hardness and stainless steel, which has good corrosion resistance and long service life.

Structural valve characteristics

1. This valve adopts a triple eccentric sealing structure, the valve seat and butterfly plate are almost wear-free, and it has a tighter and tighter 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 regardless of low temperature and high temperature.

3. The sealing surface of the disc plate adopts surfacing welding cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life.

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

5. This valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation and is not affected by the spatial position. It can be installed in any direction.

6. The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
