Features Of Trunnion Stainless Steel Ball Valve

Threaded Ball Valve is a commonly used valve now. It is loved and favored by the majority of users for its simple structure and small size. Ruitong stainless steel ball valve manufacturer summarizes the characteristics of fixed ball stainless steel ball valve.

Fixed ball stainless steel ball valve: The ball of the stainless steel ball valve is fixed and does not move after being pressurized. Fixed ball stainless steel ball valves are all equipped with floating valve seats. After being pressurized by the medium, the valve seat moves, so that the sealing ring is pressed tightly against the ball to ensure sealing. Bearings are usually installed on the upper and lower shafts of the ball, with small operating torque, suitable for high-pressure and large-diameter valves.

In order to reduce the operating torque of stainless steel ball valves and increase the reliability of sealing, oil-sealed stainless steel ball valves have appeared. Special lubricating oil is injected between the sealing surfaces to form an oil film, which enhances the sealing performance and reduces the operating torque. It is more suitable for high-pressure and large-diameter stainless steel ball valves.
