The ball of the ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and be tightly pressed against the sealing surface at the outlet end to ensure the outlet end is sealed.
The floating ball ball valve has a simple structure and good sealing performance. However, the load of the ball bearing the working medium is transmitted to the outlet seal ring. Therefore, it is necessary to consider whether the seal ring material can withstand the working load of the ball medium. This structure is widely used in low and medium pressure ball valves.
