Low Pressure Proportional Relief Valves

RL Series proportional relief valves protect pressure sensitive equipment in systems with working pressures up to 300 psig (20.6 bar) and set pressures from 10 to 225 psig (0.7 to 15.5 bar).

Set Pressures:

  • Temperature Range: -40 to 300°F (-40 to 300°C)
  • MAWP:  300 psig (20.6 bar)
  • Set Pressure Range: 10 to 225 psig (0.7 to 15.5 bar) One spring for the full set pressure range. RL Series valves are shipped with springs installed.

End Connections:

  • RL3: 1/4 in., 6 mm and 8 mm tube ends, 1/4 in. NPT and BSPT pipe ends
  • RL4: 1/2 in. and 12 mm tube ends 1/2 in. NPT and BSPT pipe ends

 Options

  • Factory set valves
  • Manual override handle
  • Seal Materials
    • Fluorocarbon FKM (Standard)
    • Nitrile
    • Ethylene Propylene
