What Is The Difference Between The Fixed Ball And Floating Ball Of A Lined Ball Valve?

Lined Ball Valve are suitable for frequent operation, opening and closing quickly and easily. They offer low fluid resistance. They have a simple structure, are relatively small, lightweight, and easy to maintain. They offer excellent sealing performance, are not restricted by installation orientation, and allow the medium to flow in any direction. They are vibration-free and quiet.

Ball valves can be categorized by structure: floating, trunnion-mounted, elastic, and oil-sealed. They can be categorized by channel type: direct-flow, angle, and tee. Tee types can be further categorized by T- and L-shaped. They can be categorized by connection method: threaded, flanged, and welded. The Difference Between Fixed and Floating Ball Valves in On-Off Ball Valves
Floating ball valves (floating ball valves, ball valves without a fixed shaft) and fixed ball valves (fixed ball valves, ball valves with a fixed shaft) are new, high-performance ball valves suitable for long-distance pipelines and general industrial pipelines. Special considerations have been taken into account in their design for safety and resistance to harsh environments. They are suitable for a variety of corrosive and non-corrosive media.

Compared to floating ball valves, during operation, the force generated by the fluid pressure in the pipeline upstream of the valve on the ball is fully transmitted to the upper and lower bearings, preventing the ball from moving. The valve seal is achieved by the spring and the pressure of the medium pushing the valve seat, thus protecting the valve seat from excessive pressure. As a result, fixed ball valves exhibit minimal seat deformation, low operating torque, reliable sealing performance, and a long service life. They are particularly suitable for high-pressure and large-diameter applications.
