Pneumatic ball valve applicable occasions profile, 2)

usually rubber ball, nylon, ptfe as pneumatic seat materials, so its pneumatic seat sealing by the limit temperature of the material. By the pneumatic valve use of metal ball, in the role of the media, plastic chairs (between Float pneumatic valve) The pressure. In certain contact pressure pneumatic valve seat, the elastic and plastic deformation occurred in some areas. Can make up for the manufacturing precision and surface roughness of deformation field, to ensure the sealing performance of pneumatic valve.
at the same time, the pneumatic seat ring are usually made of plastic, so the structure and properties of the ball to consider the choice of fire and fire, especially in petroleum, chemical, metallurgical and other industries, flammable, explosive devices and media types in systems and control, pneumatic valve, but also should pay attention to fire protection and fire prevention.
normally, double adjustment, good sealing, mud, wear and tear, reduce the channels, the rapid opening and closing action ( / turn, open and close) The high pressure (shut down Pressure) , low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere, the operating torque, pipeline system, suggested that pneumatic valve fluid resistance is small.
the ball also applies to light structure, low cut-off ( The pressure difference) The corrosive medium pipeline system. At lower temperature ( Low temperature) Equipment and pipeline pneumatic valve, the system can be used. Oxygen in the metallurgical industry in a piping system, use the handle to the ball too fat. In pipeline and gas pipeline in the mainline laid in the ground, you need to use the full size ball pneumatic valve welding. Specification requirements on performance, need to use a special structure of pneumatic valves, V. In petroleum, petrochemical, chemical, electric power, urban construction, in ℃ above pipeline system can use metal to metal sealed ball pneumatic valve working temperature.
