Ball valve sphere is floating, in the medium pressure, the ball can produce a certain displacement and tight pressure on the outlet end of the seal surface, to ensure the outlet end seal. The floating ball valve is simple in structure and good in sealing, but the ball bears all the load of working medium to the outlet seal ring, so to consider whether the sealing material can withstand the working load of the sphere medium, the sphere may be offset by the higher pressure impact.
This structure is generally used in medium and low pressure ball valves. The main feature of the ball valve is its compact structure, the seal is reliable, the structure is simple, the maintenance is convenient, the sealing face and the spherical surface often in the closed state, is not easy to be washed by the medium, is easy to operate and the maintenance, is suitable for the water, the solvent, the acid and the natural gas and so on general working medium, but also Methane and ethylene, etc., are widely used in various industries. Ball valve body can be whole, also can be modular.
