In general, ball valves are recommended in pipeline systems with two-position adjustment, strict sealing performance, mud, wear, necking channel, fast opening and closing action (1/4 turn opening and closing), high pressure cut-off (large pressure difference), low noise, cavitation and vaporization, a small amount of leakage to the atmosphere, small operating torque and low fluid resistance.

In addition, the ball valve is also suitable for light construction, low pressure shut-off (small differential pressure), corrosive media piping system.

Ball valves are also available in cryogenic (cryogenic) installations and piping systems.

In the oxygen piping system of the metallurgical industry, ball valves that have undergone a strict degreasing treatment are used.

When the main lines in oil pipelines and gas pipelines need to be buried underground, full-bore welded ball valves are used.

When regulating performance is required, a 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 ball valves can be used for pipeline systems with working temperatures above 200 degrees.
