Gear Operated 3 PCS Casted Steel Ball Valve

Trunnion Ball Valve is fixed, it does not move with medium pressure and trunnion ball vale 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. 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.
