Angle relief valves

  • Cleaned for Oxygen Service
  • 100% factory tested
  • Multiple inlet and pressure settings
  • Bubble tight seat
  • High flow rate
  • Right angle configuration eliminates direct flow through the spring and enables relief of gasses

Angle relief valves are used for the combined purpose of enhanced safety and redirection of flow. Angle relief valves perform similarly to other relief valves by releasing excess pressure, thereby protecting machinery and personnel from incidents caused by over-pressurised vessels or pipework.
