Our fixed ball valves all have floating valve seats. When subjected to the pressure of the medium, the valve seats move, causing the sealing ring to tightly press against the ball, ensuring a seal. Usually, bearings are installed on the upper and lower shafts of the ball, resulting in a small operating torque and making them suitable for high-pressure and large-diameter valves. To reduce the operating torque of the ball valve and increase the reliability of the seal, oil-sealed ball valves have emerged in recent years. Special lubricating oil is injected between the sealing surfaces to form an oil film, which not only enhances the sealing performance but also reduces the operating torque, making them more suitable for high-pressure and large-diameter ball valves.
