Application of ball valve

Usually, in two-position adjustment, strict sealing performance, mud, wear, shrinking channel, quick opening and closing action, high pressure cut-off (large pressure difference), low noise, cavitation and gasification In the pipeline system with small amount of leakage to the atmosphere, small operating torque and small fluid resistance, it is recommended to use a ball valve.
Ball valves are also suitable for pipeline systems with light structure, low pressure cut-off (small pressure difference), and corrosive media.
Ball valves can also be used in low temperature (cryogenic) installations and piping systems.
In the oxygen pipeline system in the metallurgical industry, ball valves that have undergone strict degreasing treatment are required.
When the main line in the oil pipeline and the gas pipeline needs to be buried underground, a full-bore welded ball valve should be used.
When the adjustment performance is required, a ball valve with a special structure with a V-shaped opening should be selected.
In petroleum, petrochemical, chemical, electric power, and urban construction, metal-to-metal sealing ball valves can be selected for pipeline systems with operating temperatures above 200°C.
