Metal To Metal Ball Valve
- 双恒
- China
Main features: Seat of metal to metal ball valves have special protection and tight shut-off design to be applied to some poor conditions, such as high- temperate, high pressure and abrasive mediums, to fully solve the problem of inner leakage and outer leakage, and ensure reliable sealing with zero leakage.

Product features：
1.Advanced rocket-spraying process ensures that sealing is realiable under all temperatures — pressures. With hydrogen used as fuel, this process has been applied to the sealing faces of the ball and the valve seats;
2. Flow resistance is small；
3.Piston seat, fire protection-antistatic structure design；
4.No limitation on the flowing direction of medium；
5. When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;
6.Spring loaded packing can be chosen;
7.Low emission packing can be chosen according to ISO 15848 requirement;
8.Stem extended design can be chosen;
9.Metal to metal seat design can be chosen;
10. DBB，DIB-1，DIB-2 design can be chosen；
11.The ball is fixed with a supporting plate and a fixed shaft;
