D643H/W型气动三偏心硬密封蝶阀由气动执行器和三偏心硬密封蝶阀组成。气动三偏心硬密封蝶阀具有双向密封功能,开启力矩小,灵活方便,省力节能;三维偏心结构,使蝶板越关越紧,其密封性能可靠,达到无泄漏;在阀板启闭时与阀座基本没有摩擦,减少了阀座密封面磨损,提高了蝶阀的使用寿命。阀座密封圈采用金属硬密封结构,耐温比软密封蝶阀高很多,可用于高温介质。气动执行器驱动蝶阀开关迅速,可用于快速切断。配有电磁阀,行程开关附件,方便远程控制。需要比例调节控制时要配装电气阀门定位器。

Product Features

  1. 蝶阀采用三偏心结构,开关密封面磨损小,使用寿命长。
  2. 金属硬密封结构,可以用于高温介质。
  3. 可以提高外加扭矩来提高密封性,有效保证介质密封。
  4. 气动执行器驱动开关速度快,可用于快速切断。
  5. 可配装电磁阀,行程开关,方便远程自动控制。
  6. Large-sized butterfly valves feature a truss structure, offering high strength, large flow area, and low flow resistance.
  7. 三偏心硬密封蝶阀耐高温、耐低温、耐腐蚀性。

Application Areas

广泛适用于治金、电力、石油化工、以及给排水和市政建设等工业管道上,作调节流量和载断流体使用。
