Floating pneumatic ball pneumatic ball valve The ball of the pneumatic pneumatic ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface at the outlet end to ensure that the outlet end is sealed. The floating pneumatic ball valve has simple structure and good sealing performance, but the load of the working medium borne by the ball is all transferred to the outlet seal ring, so it is necessary to consider whether the seal ring material can withstand the working load of the ball medium. This structure is widely used for middle and low pressure pneumatic ball valves.

Maintenance and treatment of corrosion-resistant pneumatic ball valve The use of corrosion-resistant pneumatic ball valve shall specify the applicable medium and scope, and select appropriate materials and gaskets for production. Before the maintenance of the pneumatic ball valve, the upstream and downstream pipeline pressure must be removed before disassembly. The disassembled parts can be cleaned by immersion. The non-metallic parts shall be taken out of the cleaning agent as soon as possible after cleaning, and shall not be soaked for a long time. The online maintenance of pneumatic ball valve requires the operation of a qualified leak stoppage engineer under pressure, and the maintenance steps can refer to Xinqing Environmental Protection's Pneumatic Ball Valve Leak stoppage Operation Manual under Pressure.
