Description of Two piece female ball valve
Ball valve generally uses rubber, nylon and PTFE as the sealing material, so its temperature depends on the sealing. Ball valve closing function worked through compressed between plastic seats under the effect of the media, Valve seat is deformed under the pressure. The deformation can compensate the manufacturing presison of the sphere and the roughness of the surface to ensure high sealing performance.
Beause the valve seat sealing ring is made of plastic, the fire resistance are taken into consideration especially in petroleum, chemical, metallurgical and other departments, In flammable and explosive medium equipment and pipe fittings, should be paid more attension..
Features:
Ball valve has high sealing performance, so it applies to slurry, abrasion, reduced chanel, rapid opening and closing movement, high pressure closure, low noise, the phenomenon of cavitation and gasification, small leakage to the atmosphere, small torque, small fluid resistance of the piping system.
In the low-temperature (cryogenic) equipment and piping system valve can also be used.
In oxygen pipeline system of the metallurgical industry, need use the ball valve with strict treatment.
When need regulating performance, should use special structure with V shaped opening of the valve.
In the petroleum, petrochemical, chemical, electric power and urban construction, the working temperature over 200 ℃ in the pipeline system can be used for metal sealing metal.
