Floating Ball Valves
CHAODA Valves Group is specialized in manufacturing Floating Ball valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. The ball of Q41F Floating Ball Valves is not fixed, and ball could move itself a little onto the outlet side seat ring with the pressure force of medium. As a result, floating ball valve could only realize single side sealing, i.e. sealing of the outlet seat.
Polymeric material such as PTFE is always chosen as the seat of floating ball valves with good sealing performance. As the material is too soft, we need to increase the Closing-Opening torque to realize needed sealing pressure ratio. To deal with this problem, double beveled or V-groove seat structure is widely used to help the sealing performance.
This seat design ensures a bigger sealing pressure ratio between the seat ring and ball when medium pressure gets smaller when the contacting area between them is small to realize reliable sealing. However, when medium pressure gets higher, the contacting area between them becomes bigger to ensure no damage occurs on the seat as the elastic seat could bear the bigger force from medium. To ball valve with small working pressure or under vacuum working condition, as the medium force couldn't seal the ball seat, preloaded force would be increase after period's using, we would use a spring-loaded seating to ensure long time reliable sealing of the valve.

Floating Ball Valves product description
Floating Ball Valves (Flanged general and butt-welding connection is optional) are suitable for using on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN260 to cut off or allow the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs. Among all types of valve, ball valve has the smallest flow resistance as it almost equals to the pipeline when full bore ball valve is fully opened.
Ball valves could be made with Full bore and Reduced bore structure. The pipeline carrying medium which is viscous or easy to be slag in it should choose full bore type to ensure regular pipe pigging. The reduced one could be used for carrying gas or medium with physical property as water for the weight of reduced one is 30% lighter than full bore valve to reduce the cost and pipeline loading. Manual/worm gear, pneumatic, electric or hydraulic actuators could be chosen by needs
