Working principle and purpose of the product:

The clamp type hard sealed butterfly valve adopts a precision J-shaped elastic sealing ring and a three eccentric multi-level metal hard sealing structure, and is used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃. It is used to regulate flow and load and break fluids.

Product Structure Features:

1. The clamp type hard sealed butterfly valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as viewed

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 in both low and high temperature conditions, with characteristics such as corrosion resistance and long service life

3. The sealing surface of the butterfly plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life

4. The large-sized butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance

5. The clamp type hard seal butterfly valve has bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction

6. The drive device can be installed in multiple stations (rotated 90 ° or 180 °) for easy user use
