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.



Reliable Stem Seal

The Below-out proof design has been adopted for the stem to ensure that even if the pressure in the body cavity is risen accidently and design with a back seat, being assembled from underneath. 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.


V type packing structure has been employed to effectively transform the pushing force of gland flange and the medium pressure into the sealing force against the stem.


The traditional packing flange design has been improved to be two-piece structure, i.e., being as a gland flanged and gland, the latter contacts the gland flange with spherical surface. Thus, the gland remains vertical always, and is lined internally with a PTFE bush to prevent the galling against and friction between the stem, which can also reduce the operation torque of the valve.


Based on customers' requirement, a packing tightening design may be employed to obtain more reliable stem packing sealing, which is loaded by beveling spring.


Anti-static Feature

The traditional packing flange design has been improved to be of two piece structure, i.e., being as a packing flange plate and a follower, the latter contacts the flange plate with spherical surface. Thus, the follower remains vertical always, and is lined internally with a PTFE bush to prevent galling against and friction between the stem, which can also reduce the operation torque of the valve.
