GEP - Floating Ball Valve

Reliable seat seal
The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features a btgger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower, where the contacting area is smaller Thus, the reliable 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 btgger 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. G.E.P. Valves 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, G.E.P. Valves floating ball valves with design can meet the requirement of API 607, API 6FA.BS 6755 and JB/T 6899.

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 accidently 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 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 med`um pressure.

Forged steel ball valve
The floating ball valve supplied by G.E.P. Valves company is generally employing casted steel valve body, however, as required by customers, forged steel valve body is also available, of which the main sizes such as flange connections and face to face ctmensions are the same as that of the cast steel ball valve

Ball valve with reduced bore
In addition to the full bore floating ball valve, G.E.P. Valves is also supplying the floating ball valve with reduced bore to satisfy different customer`s requirement, which can not only lower the cost and the pricing, but also meet customers` special requirement.
