What is bellows stop/globe valve?

The corrugated pipe shut-off valve adopts a bellows structure. The stainless steel corrugated pipe is welded on the valve stem at the lower end to prevent the process fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The double seal design will also avoid leakage if the bellows fails to fill the valve stem. The bellows are welded to the valve stem to maintain stable operation performance and avoid valve stem vibration due to valve plug vibration. The most suitable for steam, flammable, explosive, thermal oil, high purity, toxic and other medium pipelines.

      Corrugated pipe globe valve features:

      1, the product structure is reasonable, reliable sealing performance, beautiful appearance;

      2. Cobalt-based hardfacing alloy on the sealing surface, wear resistance, corrosion resistance, anti-friction performance, and long service life;

      3, stem tempering and surface nitriding treatment, have good anti-corrosion and anti-friction performance;

      4. Double-sealing of right-angle German standard bellows shut-off valve, with more reliable performance;

      5, the valve stem lifting position indication, more intuitive;

      6. The size of parts, flanges and butt welds can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
