FVF APl 602 Bellow Sealed A105 Gate Valve Class 800

FVF Bellows Sealed Gate Valve adopts double sealing structure of bellows and packing to ensure the leakage and seal at the stem.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.
