FVF BS 5352 Bellow Sealed A105N Forged Globe Valve Class 800 Class 1500
- FVF Bellows Sealed Globe Valve adopts advanced foreign technology, using double bellows design, welded to the valve stem to maintain stable operating performance, avoid the valve vibration caused by valve plug vibration.
- In particular chemical processes the fluids in the pipes are often toxic, radioactive and hazardous. Bellow sealed valves are used to prevent leakage of any toxic chemical to the atmosphere.
- At high temperature, the stem does not touch the medium to ensure zero leakage of the stem. At the same time ensure enough strength and toughness, can switch tens of thousands of times.
- The bellow can be supplied in different materials like 316Ti, 321, C276 or Alloy 625. Body material can be selected from all available materials.
