HydraForce RV08-20 Relief Valve Cartridge Direct Acting Poppet Type


The HydraForce RV08-20 valve is a screw in, cartridge style, direct acting, poppet type, hydraulic relief valve intended for lower flow circuits requiring low internal leakage.

RV08-20X blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the spring opposed poppet off its seat.

Features include:

  • Adjustments cannot be backed out of the valve.
  • Variety of pressure adjustment options including non-adjustable factory preset.
  • Adjustments options A, B, and C: positive stops prevent springs from going solid.
  • Optional spring ranges to 248 bar (3600 psi).
  • Rapid response to pressure changes.
  • Optional bi-directional pressure (requires bi-directional pressure seal option).
  • Compact size

Pressure ratings:

  • Pressure rating: 275.8 bar (4000 psi), 482.6 bar (7000 psi)
  • Burst pressure: 896.3 bar (13000 psi)
  • Relief pressure defined: pressure evident at 0.95 litres / minute (0.25 gallons/ minute)

Note that the HydraForce RV08-20 has been superseeded by the RVD58-20 in most applications. Considerations include:

  • Comparable pressure and flow ratings
  • Comparable response rate
  • Better pressure rise characteristics
  • Smaller size
  • No dynamic seal
  • Competitive cost
  • VC08-2B cavity variation is required. Some manifolds may allow drop-in replacement.
