1. Labor-saving operation: the sphere is supported by the upper and lower bai bearings to reduce friction and eliminate the excessive torque caused by the huge sealing load formed by the imported pressure pushing the sphere and the sealing seat. 2. Reliable sealing performance: PTFE uni
1. Principles of Floating Ball Valves and Trunnion Mounted Ball Valves:The ball of Floating Ball Valves is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the seal of the outlet end.Th
Double block and bleed valve generally adopts ball front valve seat sealing structure.The two valve seats of the Trunnion mounted ball valve can independently cut off the medium at the inlet and outlet ends to realize the double-break function.
