Do you know where and when ball valves are used?
Ball valves are widely used.It is recommended to use ball valve in the pipeline system with double-position regulation, strict sealing performance, mud, wear, shrinking channel, quick opening and closing action (1/4 turn opening and closing), high pressure cut-off (big pressure difference), low noise, cavitation and gasification phenomenon, small leakage to the atmosphere, small operating torque and fluid resistance.
Ball valves are also suitable for light construction, low pressure cut-off (small pressure difference), corrosive medium pipeline system.
Ball valves can also be used in low temperature (cryogenic) devices and piping systems.In the oxygen line system of metallurgical industry, ball valves with strict degreasing treatment shall be used.
When mains in oil and gas pipelines need to be buried underground, full size welded ball valves should be used.
In the demand has the regulation performance, must choose to take the v-shaped opening of the special structure of the ball valve.
In petroleum, petrochemical, chemical, electric power, urban construction, the operating temperature in 200 degrees above the pipeline system can choose metal to metal sealed ball valve.
