Wenzhou Meike Valve Co.,Ltd.

We are offering ball valves. trunnion mounted ball valve is the result of innovative engineering. It embodies all the quality, performance, rnvalue and safety features required for critical applications.rnin trunnion mounted ball valve, the ball rotates without moving on the horizontal axis, where as seats are rnfloating and free to move on the same axis. As the pressure increases the force on the seat ring by the pressurernpushes towards the ball giving bidirectional sealing.rnrnthrust due to (fluid pressure + spring) both on the upstream and downstream, pushes seat ring towards the ball for rnpositive sealing under all conditions.rnrnwhen the valve is in closed position, the fluid trapped in the body cavity is subjected to thermal expansion and the rnvalve cavity pressure increases. The excessive pressure buildup within the valve cavity is relieved automatically when rnthe pressure inside exceed the spring load on the seat.rnrninternal trunnion reduces the chance of fluid leakage to the atmosphere as in the case of external trunnion mounted ball valves.
