When do I use the ball valve

Ball valve is widely used.It is recommended to use ball valves in pipeline systems with double position regulation, strict sealing performance, mud, wear, shrink opening and closing channels, rapid opening and closing action (1/4 turn opening and closing), high pressure cut-off (large pressure difference), low noise, cavitation and gasification phenomenon, small leakage to the atmosphere, small operating torque and small fluid resistance.

Ball valves are also suitable for light construction, low pressure cut-off (low pressure differential), corrosive medium pipeline systems.
 
Ball valves can also be used in cryogenic (cryogenic) devices and piping systems.In the oxygen pipeline system of metallurgical industry, strict degreasing treatment is required for ball valves.
 
Full size welded ball valves shall be used in oil and gas pipelines where the main line shall be buried underground.
 
In the request has the regulation performance, must choose the special structure with the V-shape opening ball valve.
 
In petroleum, petrochemical, chemical, electric power, urban construction, the working temperature of more than 200 degrees of pipeline system can choose metal to metal sealing ball valve.
