进口对焊波纹管截止阀

进口对焊波纹管截止阀的阀杆采用波纹管及填料双重密封结构，确保阀杆处的无泄漏密封，特别适用于易燃、易爆、有毒及贵重介质的管路。波纹管采用不锈钢或 Inconel材料制造，波纹管密封结构设计合理，耐疲劳，使用寿命长。波纹管截止阀广泛适用于公称压力PN1.6～4.0MPa,工作温度-29～350℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，切断或接通管路介质。

The import of welded bellows valve

Imported welded bellows globe valve stem with corrugated pipe and packing a double seal structure, ensure no leakage at the valve stem seal, the pipeline is especially suitable for the inflammable and explosive, toxic and expensive medium. The corrugated pipe is made of stainless steel or Inconel material, the bellows seal structure is reasonable in design, fatigue resistance and long service life. Bellows globe valve is widely used in nominal pressure PN1.6 ~ 4.0MPa, the operating temperature of -29 to 350 DEG C petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other working conditions of the pipeline, cut off or connect the pipeline media.
