Stainless steel ball valve is suitable for what kind of occasions

Usually, in two-position adjustment, strict sealing performance, mud, wear, shrinkage passage, rapid opening and closing action (1/4 turn), high pressure cutoff (large differential pressure), low noise, cavitation and gasification Stainless steel ball valves are recommended for piping systems with small leakage to the atmosphere, small operating torque, and low fluid resistance.
 
    Since stainless steel ball valves typically use rubber and Teflon as the seat seal material, their service temperature is limited by the material of the seat seal. The cut-off function of the stainless steel ball valve is achieved by the metal ball being pressed against the plastic valve seat under the action of the medium (floating ball valve). The valve seat seal is deformed by elastic deformation in a local area under a certain contact pressure. This deformation can compensate for the manufacturing precision and surface roughness of the sphere and ensure the sealing performance of the stainless steel ball valve.
    Since the valve seat seal of the ball valve is usually made of plastic, in the structure and performance of the stainless steel ball valve, the fire resistance and fireproof of the ball valve should be considered, especially in the petroleum, chemical, metallurgical and other departments, in the flammable and explosive. Ball valves are used in equipment and pipe systems of the media, and fire resistance and fire protection should be paid more attention.

    Ball valves are also suitable for use in piping systems with light construction, low pressure cut-off (small differential pressure), corrosive media.

    Stainless steel ball valves are also available in low temperature (deep cold) units and piping systems.

    In the oxygen pipeline system of the metallurgical industry, a stainless steel ball valve that has been strictly degreased is used.

    When the main line in the oil pipeline and the gas pipeline is to be buried underground, a full-bore welded ball valve is required.

    When it is required to have adjustment performance, a stainless steel ball valve with a special structure with a V-shaped opening is required.

    In petroleum, petrochemical, chemical, electric power, and urban construction, metal-to-metal sealed stainless steel ball valves are available for piping systems with operating temperatures above 200 °C.
