Electric fixed ball valve （電動固定球閥）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 （防爆球閥）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.

 電動固定球閥/電動球閥在管道上主要用于切斷、分配和改變介質(zhì)流動方向。電動固定球閥在設(shè)計(jì)上采用了樞軸結(jié)構(gòu)，這一設(shè)計(jì)特點(diǎn)保證了球體準(zhǔn)確位置。閥座采用彈簧結(jié)構(gòu)，將閥蓋推向球體，低壓密封效果遠(yuǎn)超同類閥門產(chǎn)品。
    電動固定球閥/固定電動球閥樞軸采用防吹出保護(hù)結(jié)構(gòu)，低摩擦系數(shù)的軸承等。具有性能優(yōu)異，可靠性高，用途廣泛，價格合理等優(yōu)點(diǎn)。
    按其截面分為兩分式和三段式兩種固定球閥。
    電動固定球閥/電動法蘭球閥適用于：化工、石油、天然氣、冶金、等行業(yè)及含硫化氫介質(zhì)、雜質(zhì)多、腐蝕嚴(yán)重的天然氣長輸管線。
