The Hydraforce RVD50-20H-0-N-32/ (5612508) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection by limiting pressure. This model effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, ensuring quick response to load changes with low hysteresis and minimal internal leakage. The valve features a robust construction with a hardened poppet and cage for extended durability. Notably, adjustments cannot be undone from the valve, and the adjuster height remains constant when modifying the pressure setting. It accommodates optional spring ranges up to 345 bar (5000 psi), providing rapid response to pressure fluctuations within an industry-common cavity. The RVD50-20H-0-N-32/ supports a maximum pressure rating of 413.7 bar (6000 psi), proof pressure of 785.4 bar (11000 psi), and burst pressure of 1515.8 bar (22000 psi). It defines crack pressure at a flow rate of 0.95 lpm (0.25 gpm) and has a reseat pressure nominally at 85% of the crack pressure with minimal internal leakage up to 80% of nominal flow rate at only 0.25 ml/min (5 drops/min). The valve operates efficiently across various temperatures depending on seal material: -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. This relief valve is suitable for mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains optimal performance under contamination levels up to ISO code 18/16/13 per ISO 4406 standards. Weighing between approximately 0.20 kg and 0.25 kg depending on configuration, it features an internal wetted surface area ranging from about 151 cm\u00b2 to158 cm\u00b2 and installs into VC10-2 cavities using specified torque values between 63.7 N-m and71.9 N-m without orientation restrictions.
