Metal hard seal butterfly valve product features and functions introduced:
The metal hard sealing butterfly valve is made of precision J-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure. It is widely used in industrial pipes such as metallurgy, electric power, petrochemical industry, and water supply and drainage and municipal construction with medium temperature ≤ 425 °C. For regulating flow and load fluid use.
The main features of the metal hard seal butterfly valve are as follows:
1. The metal hard sealing butterfly valve adopts three eccentric sealing structure, the valve seat and the butterfly plate have almost no wear, and the seal function is more and more tight.
2. The sealing ring is made of stainless steel. It has the double advantages of hard metal seal and elastic seal. It has excellent sealing performance under low temperature and high temperature, and has corrosion resistance and long service life.
3. The sealing surface of the butterfly plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life.
4. Large-size butterfly plate adopts truss structure, high strength, large flow area and small flow resistance
5. The metal hard sealing butterfly 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 drive unit can be installed in multiple stations (rotated 90° or 180°) for user convenience.
