Reliable seat seal
The structure design of elastic sealing ring has been adopted for floating ball valve. This seat design features a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower, where the contacting area is smaller. Thus, the reliable sealing is encusred. When the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the ball sealing ring transforms elastically to undertake the bigger force pushed by the medium without any damage.
Fire safe design
With the valve heated in a fire application, the Non-metal material parts such as seat sealing ring of PTFE, stem back seat gasket, gland packing, and the sealing gasket between body and bonnet might disintegrate or be damaged due to high temperature. Coosai Valve's specially designed structure of auxiliary metal to metal seal is provided to effectively prevent both internal ball and external ball leakage of the valve. As per required by customers, Coosai Valve's floating ball valves with fire safe design can meet the requirement of API607, API6FA, BS6755.
