Trunnion mounted Ball ValvesBall of trunnion ball valve is fixed, it does not move with medium pressure. Trunnion ball valve has floating seats. The seats move with the medium pressure to tight the ball and seal ring to ensure sealing reliability. Bearings could be mounted in top shaft and bottom shaft, which reduces operation torque. This is widely used in valves with high pressure and big sizes. To decrease the operation torque and increase sealing reliability, lubricated ball valves are adopted in recent years. A special sealant is injected between sealing faces of lubricated ball valve to create a layer. This increase the sealing reliability while decreasing the operation torque, which is better for high pressure, big sized ball valve.WINDMILL trunnion mounted ball valve series featuring with 2-PC or 3-PC split body, trunnion mounted ball, It is ideal for frequent on-off flow control in big size and high pressure pipeline. WINDMILL trunnion mounted ball valve are fire safe te
