10D673H Pneumatic Wafer Type Hard Seal Butterfly Valve
D673H pneumatic wafer type hard sealing butterfly valve adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure, which is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction where the medium temperature is ≤425℃ It is used for adjusting flow and carrying and breaking fluid on industrial pipelines. The valve adopts a triple eccentric structure. The valve seat and the sealing surface of the disc plate are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has a two-way sealing function. The product conforms to the national GB/T13927-92 valve. Pressure test standards.
D673H pneumatic hard seal butterfly valve features:
The 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.
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.
The sealing surface of the disc plate adopts surfacing welding cobalt-based cemented carbide, which is resistant to wear and has a long service life.
The large-size butterfly plate adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.
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.
The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
