The stainless steel ball valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is used to make the structure easy to seal, and the valve seal of the ball valve can increase with the increase of the medium pressure. The change of the internal structure of the stainless steel ball valve makes its The mechanical properties are better than ordinary gray cast iron, and other properties are not damaged. Therefore, valves made of ductile iron can be used at higher pressures than those made of gray cast iron.

The one-piece stainless steel ball valve uses a new type of sealing material on the valve seat. Compared with similar products, the service life of the ball valve sealed with PTFE is extended by 3 to 5 times. Stainless steel ball valve has the advantages of stable performance, reliable sealing, low friction, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance and long life.
