No torsion of bellows and proper stem guiding of non-rotating stem prevents torsion of bellows and ensures a long cycle life. A typical long cycle life of bellows valve is more than 10,000 cycles.
In particular, chemical fluids processed in the pipes are often toxic, radioactive, and hazardous. Bellow sealed valves are used to prevent leakage of any toxic chemicals to the atmosphere. The bellow can be supplied in different materials like 316Ti, 321, C276, or Alloy 625. Red Point® has a large inventory of bellows to cover a range of valves from 1/2 to 2 inches with a pressure rating of 150 to 1,500 pounds.
Bellow sealed globe valves by 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-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)
