Product Description


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.
Design Features
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;
Double block and bleed;
Cavity pressure self relief;
Blowout-proof stem;
Seats are Tungsten Carbide HVOF(High Velocity Oxy Fuel) or overlay cladding coated with metal to metal contact between seats and ball, with metal to metal seat sealing characteristics, and it can clean dirt at surface of the gates.
Hardness of coating surface: up to HRC68~ 72;
Bonding strength of coating: ≥10000Psi;
Thickness of coating: 0.3 - 0.5 mm;
The precise "one-to-one" grinding process ensures the precise "one-to-one" grinding between the ball and the valve seat;
