Electric fixed ball valve （电动固定球阀）in the pipe is mainly used for cutting, distribution and change the direction of media flow. Electric fixed ball in the design of the pivot structure, this design features to ensure that the sphere of the exact location. Seat spring structure, the valve cover to push the sphere, low pressure sealing effect is far more than a similar valve products.
    Electric fixed ball （防爆球阀）pivot using anti-blow to protect the structure, low coefficient of friction bearing. Has the advantages of performance, high reliability, versatility, and reasonable prices.
    Their cross-section is divided into two fraction and three-two fixed ball.
    Applies to electric fixed ball: chemical, petroleum, natural gas, metallurgy, and other industries, and hydrogen sulfide-containing media, impurities, corrosion serious long distance gas pipeline.

 电动固定球阀/电动球阀在管道上主要用于切断、分配和改变介质流动方向。电动固定球阀在设计上采用了枢轴结构，这一设计特点保证了球体准确位置。阀座采用弹簧结构，将阀盖推向球体，低压密封效果远超同类阀门产品。
    电动固定球阀/固定电动球阀枢轴采用防吹出保护结构，低摩擦系数的轴承等。具有性能优异，可靠性高，用途广泛，价格合理等优点。
    按其截面分为两分式和三段式两种固定球阀。
    电动固定球阀/电动法兰球阀适用于：化工、石油、天然气、冶金、等行业及含硫化氢介质、杂质多、腐蚀严重的天然气长输管线。
