Bellow Sealed Gate Valves

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. The bellow can be supplied in different materials like 316Ti, 321, C276 or Alloy 625. Body material can be selected from all available materials.

Our bellow sealed gate valves are available as forged or cast valves featuring exotic material options with short delivery times.

Advantages are:

  • Long cycle life bellows – 3000 cycles
  • Non-rotating stem prevents torsion of bellows.
  • Two secondary stem seals: a) Backseat in open position; b) Graphite packing.
  • Seating faces hardfaced with CoCr alloy, ground and lapped.

Red Point® has a large inventory of 321 and C276 bellows to cover a range of valves from 1/2 to 2 inches with a pressure rating of 150 to 1.500 pounds.

321 bellows are typically used in medium like: hydrogen, steam, sour service, heat transfer fluid, ethylene oxide.

C-276 bellows are typically used in medium like: suphuric acid, hydrofluoric acid, hydrochloric acid, chlorine.

Bellow sealed gate valves from Red Point® can be deployed for a wide variety of applications in the oil & gas and petrochemical industries when high quality, reliable valves are required. A few example applications include:

  • High-temperature services
  • High-cycle and switching services
  • Emergency shutdown valves
  • High-integrity pressure protection system
  • High-pressure oxygen, nitrogen, or hydrogen
  • Solids handling (powders, fines, dust, and catalysts)
  • Polyethylene or polypropylene
  • Coal conversion & gasification
  • Thermal fluids
  • Separator, filter, and drying systems
  • Compressor stations
  • On/off isolation service
  • Oil & gas manifolds
