Bellows gate valve opening and closing parts are plug shaped disc, sealing surface is flat or conical, disc along the center line of the fluid for linear movement. Stem movement form, there are lifting rod type (stem lifting, handwheel not lifting), there are lifting rotary rod type (handwheel and stem rotating lifting together, nut in the valve body). The globe valve is only suitable for full open and full closed, not allowed to adjust and throttle. This type of valve in the pipeline should generally be installed horizontally. Bellows gate valves are especially suitable for flammable, explosive, toxic and valuable media pipelines.
Structural features:
The valve stem of bellows gate valve adopts double sealing structure of bellows and packing to ensure no leakage sealing at the valve stem, especially suitable for pipelines with inflammable, explosive, toxic and precious media. Bellows made of stainless steel or Inconel material, bellows seal structure design is reasonable, fatigue resistance, long service life.
