RB Series

Bleed valves can be used on instrument devices such as multi-valve manifolds or gauge valves to vent signal line pressure to atmosphere before removal of an instrument or to assist in calibration.


  • Compact design for easy installation
  • Hardened stem and tip to extend cycle life
  • Working pressure up to: 10000 psig (690 bar)
  • Working temperature: -65°F to -850°F (-54°C to 454°C)
  • Variety of end connections
  • leak-tight performance testing with Nitrogen or compressed air for every valve at the rated pressure (not higher that 6000 psig) to meet the requirement of no visible leak.

Pressure VS Temperature

Ratings based on all metal seals. Ratings limited to:

  • -20°F (-28°C) min with steel
  • 450°F (232°C) max with SAE end connections using fluorocarbon FKM O-ring
  • 4500 psig (310 bar) max with SAE end connections


When installing a bleed valve, position the vent tube to direct system fluid away from operating personnel. Always open bleed valves slowly. These valves contain no packing, so some fluid weepage will occur when the valves are opened. Operating personnel must protect themselves from exposure to system fluids.
