The Hydraforce RV08-22H-0-N-26/18 (5601403.18) is a high-performance hydraulic relief valve designed to serve as a pressure limiting device in demanding hydraulic circuits. This screw-in, cartridge-style valve is direct acting and features a differential area, poppet-type construction that ensures low hysteresis and minimal internal leakage. The RV08-22H model blocks flow from port 2 to port 1 until the pressure at port 2 is sufficient to unseat the poppet, making it an effective solution for controlling pressure surges. This model offers various pressure adjustment options, including non-adjustable factory presets and adjustments with positive stops to prevent spring solidification. It also supports optional bi-directional pressure with the necessary seal option, and its hardened poppet and cage construction ensures long-lasting durability. The valve can handle optional spring ranges up to 248 bar (3600 psi) and has been rated for smooth response under pressure surges. With an industry-common cavity size of VC08-2, this compact valve is suitable for a wide range of applications requiring reliable performance under challenging conditions. It has a flow rating of 30.3 lpm (8 gpm) at maximum pressure and maintains maximum internal leakage of just 0.25 ml/min at up to 85% of its nominal setting. Temperature ratings vary based on seal material: from -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. Its fluid compatibility includes mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. The RV08-22H features a robust design capable of handling proof pressures up to 496.4 bar (7000 psi) and burst pressures reaching 1037.7 bar (16168 psi). Installation specifications include cartridge installation torque between 25.8 to 28.5 N-m and plug torque from 33.9 to 36.7 N-m, ensuring secure fitting in hydraulic systems without orientation restrictions.
