Product Details

Floating Ball Valve

    

   The sphere of the ball valve is floating. Under the action of medium pressure, the sphere can produce a certain displacement and press on the sealing surface of the outlet end to ensure the sealing of the outlet end. The structure of the floating ball valve is simple and the sealing property is good, but all the loads of the sphere bearing the working medium are transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the sphere medium, and the sphere may shift when subjected to higher pressure impact. This structure is generally used for medium and low pressure ball valves. The main characteristics of ball valve are compact structure, reliable seal, simple structure, convenient maintenance, closed state of sealing surface and sphere, not easy to be eroded by medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas and other general working media, and also suitable for poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., which have been widely used in various industries. The ball valve body can be integral or combined.
