METAL TO METAL BALL VALVE

Metal to Metal Ball Valves have special protection and tight shut-off design so that it can 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.
