Your Professional Valve Solution

|
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 is necessary to consider whether the ring material can withstand the load of media 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.
