The characteristics of hard seal ball valve are as follows:
1. The metal hard seal ball valve adopts a three eccentric sealing structure, with almost no wear between the valve seat and the butterfly plate, and has the sealing function of tightening as you look
2. The seal ring is made of stainless steel, which has the dual advantages of hard metal seal and elastic seal. It has excellent sealing performance, corrosion resistance, long service life and other characteristics no matter at low temperature or high temperature
3. The sealing surface of butterfly plate is made of hardfacing cobalt base carbide, which is abrasion resistant and has a long service life
4. Quilting frame structure is adopted for large-sized butterfly plate, with high strength, large flow area and small flow resistance
5. The metal hard seal ball valve has a two-way sealing function, and can be installed in any direction without the restriction of medium flow direction and the influence of space position
6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °) for the convenience of users.
The above are the characteristics of the hard seal ball valve, and I hope it will be helpful to everyone.
