The Hydraforce RVD58-20A-0-P-50 (5612908) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for pressure limiting in hydraulic circuits. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 overcomes the poppet's resistance, ensuring circuit protection. This valve is known for its rapid response to load changes, low hysteresis, minimal pressure rise, and reduced internal leakage. It features a compact and economical design with hardened poppet and cage components for extended durability. The valve offers optional spring ranges up to 350 bar (5076 psi) and includes high durometer Buna and Fluorocarbon seals for enhanced performance. The RVD58-20A-0-P-50 has a pressure rating of 350 bar (5076 psi) at port 1 and 207 bar (3000 psi) at port 2, with proof and burst pressures of 413 bar (10,000 psi) and 1379 bar (20,000 psi), respectively. It exhibits a crack pressure defined as evident at a flow rate of 0.95 lpm (0.25 gpm) and nominal reseat pressure at approximately 90% of the crack pressure. The flow rating is up to 37.9 lpm (10 gpm) from port 1 to port 2 under maximum pressure conditions. Operating fluid temperatures range from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) with polyurethane seals. The valve withstands ambient temperatures between -40 and +70 \u00b0C (-40 to +160 \u00b0F). It includes corrosion protection rated for up to 230 hours in salt spray per ASTMB117 standards and supports fluid viscosity ranging from 7.4 to 420 cSt. Installation specifications include a cavity size of VC08-2B with an installation torque requirement of between 44.7 and 50.2 N-m (33 to 37 ft-lb).
