Product description:
Bellows structure is used inside, stainless steel bellows welded at the bottom of the stem, to prevent process fluid erosion valve stem. The other end is positioned between the valve body and the valve cover to form a static seal. Double seal design, if bellows failure, stem packing will also avoid leakage, bellows welded to stem to maintain stable operation performance, avoid stem vibration caused by valve plug vibration. Most suitable for steam, flammable, explosive, heat transfer oil, high purity, toxic and other media on the pipeline.
Characteristic:
- The utility model has the advantages of reasonable product structure, reliable sealing performance and beautiful appearance.
- Stem conditioning and surface nitriding treatment, good resistance to corrosion and friction.
- Right angle German standard bellows stop valve double seal, more reliable performance.
- Valve lift position indicator, more intuitive.
- Sealing surface surfacing Co base carbide, wear resistance, corrosion resistance, good friction resistance, long service life.
