Available in low, medium, high and extra high pressure models, R6000 right angle relief valves provide users with high accuracy and consistency of cracking and reseat pressures. Furthermore, narrow pressure ranges (cracking pressures) for each model can be factory pre-set according to customer specifications. PED certification and CE marking are standard for all models. All R6000 relief valves are offered with multiple end connections to ensure application versatility.

Low Pressure (5 - 550 psig)
Back pressure affects cracking pressure on low pressure version

Zero friction poppets
  • Increases accuracy of cracking pressure and reseat pressure.
  • Improves consistency of cracking pressure and reseat pressure.

    Encapsulated Seat Seal
  • Maintains small contact surface area.
  • Protects seat from erosion due to flow.

    Raised seal lip on poppet minimizes contact with seat, eliminating friction and preventing overstressing of the O-ring
    6 pressure spring ranges improve accuracy
    Caps and bonnets are pre-drilled for lockwire
    Multiple end connections available
