Floating Ball Valve

> The ball in a floating ball valve is free to move and under the medium pressure,the ball can shift slightly and press tightly against the sealing surface at the outlet end, ensuring the sealing of the outlet end.

> The floating ball valve has a simple structure and provides excellent sealing performance. However, the load exerted on the ball by the working medium is entirely transferred to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the medium. When subjected to high pressure impact, the ball may shift. Generally applicable to medium and low pressure ball valves.

Trunnion-Mounted Ball Valve

> The trunnion-mounted ball valve operates with a 90-degree rotation,and is primarily designed for on/off service. It features a spring-loaded floating seat mechanism that maintains positive sealing against both upstream and downstream sides, regardless of the valve being fully open or closed. Any trapped medium in the body middle chamber can be discharged through the discharge valve. When abnormal pressure buildup occurs in the chamber due to temperature rise, the valve automatically releases pressure through its seat design without relying on a safety valve, significantly enhancing the safety of the pipeline system. The trunnion-mounted ball valves are suitable for industrial applications that requiring tight shut-off and critical positioning.

> The trunnion-mounted ball valve features upper and lower bearing supports that significantly reduce friction and eliminate the sealing load torque caused by inlet pressure.

> This design is particularly suitable for high-pressure working applications and requires relatively low operating torque.
