Product Structure Features
1. This 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 temperatures, corrosion resistance, and long service life.
3. The sealing surface of the disc 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. This valve has a 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.
