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, closed, under the action of medium pressure, the ball body will not produce displacement, more stable work. Electric ball valve is 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 is widely used in various industries.
Ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries; Mainly suitable for light structure, low pressure cut-off (small pressure difference) corrosive media pipeline system. 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 the oil pipeline and gas pipeline needs to be buried underground, the full-diameter welded ball valve should be used. Ball valves of special structure with 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.
