Wafer Type Metal Hard Seal Butterfly Valve
On the basis of our company's introduction of foreign advanced technology, the wafer-type metal hard-seal butterfly valve adopts a precision J-shaped elastic sealing ring and a three-eccentric multi-layer metal hard-seal structure. It is widely used in metallurgy and electric power with a medium temperature of ≤425℃ , Petrochemical industry, as well as industrial pipelines such as water supply and drainage and municipal construction, used for regulating flow and carrying and breaking fluid. The valve adopts a triple eccentric structure. The valve seat and the sealing surface of the disc 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.
Wafer Type Metal Hard Seal Butterfly Valve Features:
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, and it has excellent performance regardless of low temperature and high temperature.
3. Excellent sealing performance, corrosion resistance and long service life.
4. The sealing surface of the disc plate adopts surfacing welding cobalt-based cemented carbide, the sealing surface is wear-resistant and has a long service life.
5. The large-size butterfly plate adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.
6. 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.
7. The moving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
