Product Description

A trunnion ball valve has an additional mechanical anchoring of the ball at the top and the bottom, which is suitable for larger and higher pressure valves, DBV Trunnion mounted Ball valves are With Soft or metal-seated Design putting a pre- mium on safety and usability.

 

The Ball of trunnion ball valve is fixed, it does not move with medium pressure. Trunnion ball valve has floating seat, the seats move with the medium pressure to tight the ball and seal ring to ensure sealing reliability. Bearings could be mounted in top or bottom stem, which efficiently reduces operation torque. Which is suitable for widely service 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 valves.
