Overview of Wafer-type Multi-layer Metal Hard Sealed Butterfly Valve
The wafer-type multi-layer metal hard sealed butterfly valve adopts a three-eccentric structure. The valve seat and the disc plate sealing surface 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 meets the national GB/T13927-92 valve pressure test standard. The electric wafer-type metal hard sealed butterfly valve adopts an accurate J-shaped elastic sealing ring and a three-eccentric multi-layer metal hard sealing structure. It is widely used in industrial pipelines such as metallurgy, electricity, petrochemicals, water supply and drainage, and municipal construction with a medium temperature of ≤425℃ to adjust the flow and carry and cut off the fluid. The valve adopts a three-eccentric structure. The valve seat and the disc plate sealing surface are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The electric hard sealed butterfly valve has a two-way sealing function. The product meets the national GB/T13927-92 valve pressure test standard.
Features
1. This valve adopts a three-eccentric sealing structure, the valve seat and the butterfly plate are almost wear-free, and has a sealing function that becomes tighter and tighter.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance regardless of low or high temperatures, and has the characteristics of corrosion resistance and long service life.
3. The sealing surface of the disc plate is made of surfacing cobalt-based hard alloy, which is wear-resistant and has a long service life.
4. The large-size butterfly plate adopts a lattice structure with 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, nor is it affected by the spatial position. It can be installed in any direction.
6. The drive device can be installed in multiple positions (rotated 90° or 180°) for easy user use.
