The Hydraforce RV08-20H-8T-N-18/15 (5600453.15) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve designed for lower flow circuits requiring minimal internal leakage. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to move the spring-opposed poppet off its seat. The valve features various pressure adjustment options, including non-adjustable factory presets with positive stops to prevent springs from solidifying. It offers optional spring ranges up to 248 bar (3600 psi) and provides rapid response to pressure changes. The valve is compact and includes an optional bi-directional pressure feature that requires a specific seal option. The RV08-20H-8T-N-18/15 operates with a maximum flow rating of 22.7 lpm (6 gpm) at maximum pressure and maintains a maximum internal leakage of 0.25 ml/min (5 drops/min). It can handle operating fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, or -54 to 107 \u00b0C (-65 to 225 \u00b0F) with urethane seals. This relief valve supports mineral-based or synthetic fluids with lubricating properties and accommodates fluid viscosity ranges from 7.4 to 420 cSt. Installation requires a VC08-2 cavity, and the cartridge installation torque ranges between 25.8 and 28.5 N-m (19 to 21 ft-lb), while the maximum allowable torque is up to 40.7 N-m (30 ft-lb). The unit's weight varies slightly depending on configuration but generally falls between approximately 0.16 kg (0.35 lb) and 0.22 kg (0.47 lb). Seal kits are available for maintenance needs, ensuring optimal performance in hydraulic systems where precise pressure management is essential.
