High pressure ball valve Fire safe design
With the high pressure ball valves heated in a fire application, the nonmetalmaterial parts such as seat sealing ring of PTFE, stem back seatgasket, gland packing, and the sealing gasket between bodyand bonnet might disintegrate or be damaged due to high temperature. WINDMILL specially designed structure of auxiliary metal to metal seal is provided to effectively prevent both internaland external leakage of the valve. As required by Customers, WINDMILL floating ball valve with design can meet the requirement Of API 607, API 6FA, BS 6755 and JB/T 6899.
High pressure ball valve Reliable stem seal
The blow-out proof design has been adopted for the stem to ensure that even if the pressure in the body cavity is risen acc-idently and the packing flange becomes invalid,the stem may not be blown out by medium. The stem features the design with a backseat, being assembled fromunderneath. The sealing force against the backseat gets higher as the medium pressure becomes higher. So the reliable seal of the stem can be assured under variable medium pressure.
High pressure ball valve Reliable stem seal
V type packing structure has been employed to effectively transform the pushing force of the high pressure ball valve gland flange and the medium pressure into the sealing force against the stem.
