Floating ball valve


Floating ball valve has simple structure and good sealing.However,the ball delivers all the load of the working medium to the exit seal ring,so it is necessary to consider whether the ring material can withstand the load of medium when working or not.If not,impacted by high pressure,the ball may be shifted,so this kind of structure is generally used for low and medium pressure valve.THe tightness of the valve is guaranteed by the floating ball,which when pressurized,moves to the seat. The operation of the valve is always on-off with 90°movement and the operation can be manual or implemented according to the requests.
