The JL600-Q1 pneumatic ball valve is an important actuator in the industrial automation control system. It can be controlled remotely and can meet the needs of computer program control; ball valves are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, Electricity, municipal administration, steel and other industries; mainly 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) devices and pipeline systems. In the oxygen pipeline system of the metallurgical industry, ball valves that have undergone strict degreasing treatment are required. When the main pipes in the oil and gas pipelines need to be buried underground, full-diameter welded ball valves are required. When the adjustment performance is required, a ball valve with a special structure with a V-shaped opening should be selected. In petroleum, chemical, electric power, and urban construction, hard metal sealed ball valves can be used for piping systems with operating temperatures above 200 degrees.
