Product Introduction
The valve is generally used for high pressure and large diameter of various pipelines, using the upper and lower stem fixed spool (shaft support type) and movable sealing seat design. When closed, under the action of medium pressure, the ball body will not produce displacement, resulting in more stable operation. Electric ball valves are usually connected with the ball on the upper and lower shaft, equipped with rolling bearings or sliding bearings, to reduce the friction force generated by the journal when opening and closing, reduce the operating torque, and are widely used in various industries.
Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, paper making, pharmaceuticals, water conservancy, electric power, municipal, steel, and other industries. They are mainly suitable for light structure, low-pressure cutoff (small pressure difference) corrosive media pipeline systems. Ball valves are also available in low-temperature (cryogenic) devices and piping systems. In the oxygen piping system of the metallurgical industry, ball valves with strict degreasing treatment are required. When the main line in oil and gas pipelines needs to be buried underground, a full-diameter welded ball valve should be used. Ball valves with special structures and V-shaped openings should be selected when regulating performance is required. In petroleum, chemical, electric power, and urban construction, hard metal sealed ball valves can be selected for piping systems with operating temperatures above 200 degrees Celsius.
