Right Angle Relief Valve
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 specifi cations. PED certifi cation and CE marking are standard for all models. All R6000 relief valves are off ered with multiple end connections to ensure application versatility.

Typical Applications
  • Beverage dispensing equipment
  • Gas pilot plants
  • Petrochemical test labs
  • Off shore oil platform heating lines
  • Pharmaceutical sterilization and packaging systems
    •
    Unit of Measure

    Features & Benefits

    		 N/A Low Pressure (5 – 550 psig) 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 fl ow.

    • 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
  • Special High Tolerance NPT Thread

    • High Pressure (150–6000 psig)
    3 models available:
  • Medium (150–2500 psig)—6 spring ranges improve accuracy
  • High (150–5000 psig)—7 spring ranges improve accuracy
  • Extra High (5000–6000 psig)—one spring

    • Delta stem seal design prevents friction which increases accuracy of cracking pressure and reseat pressure.
    Balanced poppet design allows cracking pressure to stay the same regardless of backup pressure.
    Orifi ce sizes: 0.082", 0.094", 0.188"
    Multiple end connections available.
    Optional manual override handle
