The main features of valve is its own compact, valves, sealing reliable, Shandong stainless steel valves, simple structure, easy maintenance, with the spherical sealing surface often in the closed state, can not easily be medium erosion, easy operation and maintenance for water, solvents, acid and natural gas general working media, but also to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, in various sectors has been widely used. Ball valve can be integral, Weifang steel valves, may also be modular. Ball parameters 1, nominal pressure or pressure level: PN1.0-32.0MPa, ANSI CLASS 150-900, JIS10-20K; 2, nominal diameter or diameter: DN6 ~ 900, NPS 1/4 ~ 36; 3, Connection : flanged, welded, threaded, socket weld; 4, suitable temperature: -196 ℃ ~ 540 ℃; 5, the driving modes: manual, worm gear, pneumatic, electric, hydraulic, gas-hydraulic, electro-hydraulic linkage; 6, body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Choice of different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. Ball is not only simple structure, good sealing performance, but also to some of the smaller nominal diameter within the range of size, light weight, less material consumption, small installation size, and the drive torque is small, simple, easy to open and close fast, is near One of the fastest growing valve varieties ten years of development. Ball is evolved from the stopcock comes as its opening and closing parts of a sphere, the use of the ball around the stem axis 90 ° rotation to achieve the purpose of opening and closing. Ball valves in the pipeline is mainly used for cutting, distribution and change the direction of media flow, designed ball valve V-shaped opening also has a good flow regulation.
