The Hydraforce RVD50-20A-0-N-42 (5612564) 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 is sufficient to displace the poppet. This valve is known for its rapid response to load changes, featuring low hysteresis, minimal pressure rise, and reduced internal leakage. The construction includes a hardened poppet and cage for enhanced durability. It offers optional spring ranges up to 345 bar (5000 psi) and maintains a constant adjuster height during pressure adjustments. The RVD50-20A-0-N-42 operates within a pressure rating of up to 413.7 bar (6000 psi), with proof and burst pressures of 785.4 bar (11000 psi) and 1515.8 bar (22000 psi), respectively. This relief valve is capable of handling flow rates up to 113.6 lpm (30 gpm) from port 1 to port 2 at maximum pressure, with internal leakage limited to 0.25 ml/min (5 drops/min) up to 80% of nominal settings. It supports a wide range of operating fluid temperatures depending on seal types: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane or urethane seals. The RVD50-20A-0-N-42 withstands corrosion for up to 960 hours in salt spray per ASTM B117 standards and accommodates fluids that are mineral-based or synthetic with lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation requires a VC10-2 cavity and torque between 63.7 and 71.9 N-m (47 to 53 ft-lb), without orientation restrictions. Seal kits are available for maintenance needs, ensuring continued optimal performance in various applications requiring reliable hydraulic circuit protection.
