The Hydraforce RV08-22H-0-N-04/0.50 (5601400.0.50) is a screw-in, cartridge-style hydraulic relief valve designed for demanding hydraulic circuits that require low hysteresis and minimal internal leakage. This direct-acting, differential area, poppet-type valve effectively limits pressure by blocking flow from port 2 to port 1 until the pressure at port 2 is sufficient to unseat the poppet. Notable features include a variety of pressure adjustment options with positive stops to prevent spring solidification, optional bi-directional pressure capability, and hardened components for enhanced durability. The relief valve offers optional spring ranges up to 248 bar (3600 psi), ensuring smooth responses to pressure surges within an industry-common cavity design. This compact valve boasts a maximum flow rating of 30.3 lpm (8 gpm) at peak pressure and maintains internal leakage at a maximum of 0.25 ml/min (5 drops/min) up to 85% of its nominal setting. It withstands operating fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, while fluorocarbon and polyurethane seals extend this range further for specialized applications. The RV08-22H supports fluids with viscosities between 7.4 and 420 cSt and operates best when contamination levels are maintained at or below ISO 4406's standard of 18/16/13. Installation specifications include a cartridge installation torque range of 25.8 to 28.5 N-m (19 to 21 ft-lb), with a maximum allowable torque of 40.7 N-m (30 ft-lb). It fits into VC08-2 cavities and does not have orientation restrictions during installation, making it versatile for various setups in hydraulic systems requiring reliable pressure control solutions.
