Construction and Features of Floating Ban Valve

The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features a bigger sealing pressure ratio between the ring surface and the ball when medium pressure get slower, where the contacting area is smaller.  Thus, there liable seal is ensured.  When the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to undertake the bigger force pushed by the medium without any damage.

With the valve heated in a fire application,thenonmetal material parts such as seat sealing ring of PTFE, stem backseat gasket, gland packing, and the sealing gasket between body and bonnet might disintegrate or be damaged due to high temperature.  JFlow’s specially designed structure of auxiliary metal to metal seal is provided to effectively prevent both internal and external leakage of the valve.  As required by customers.  JFlow’s floating ball valves with fire safe design can meet the requirements of API 607, API6FA, 886755 and JBff6899.
