The Hydraforce RVD50-20C-0-P-50 (5612588P) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for pressure limiting in hydraulic circuit protection. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, providing rapid response to load changes with minimal hysteresis, pressure rise, and internal leakage. The valve features a non-backout adjustment mechanism and maintains constant adjuster height during pressure adjustments. Constructed with a hardened poppet and cage for durability, it offers optional spring ranges up to 345 bar (5000 psi) and operates within an industry-common cavity. This relief valve boasts a pressure rating of 413.7 bar (6000 psi), with proof and burst pressures of 785.4 bar (11000 psi) and 1515.8 bar (22000 psi), respectively. It defines crack pressure at a flow of 0.95 lpm (0.25 gpm) and reseats at approximately 85% of crack pressure with minimal leakage. The flow rating is set at 113.6 lpm (30 gpm) from port 1 to port 2 at maximum pressure, while maintaining internal leakage below 0.25 ml/min. Temperature ratings vary based on seal material: -40 to 100 \u00b0C for Buna N seals, -26 to 204 \u00b0C for fluorocarbon seals, and -54 to 107 \u00b0C for both polyurethane and urethane seals. The unit can withstand storage temperatures from -40 to 70 \u00b0C and ambient conditions within the same range. Additional specifications include corrosion protection tested up to 960 hours in salt spray per ASTM B117 standards, compatibility with mineral or synthetic fluids with lubricating properties, fluid viscosity range from 7.4 to 420 cSt, and installation torque requirements of 63.7 to 71.9 N-m. This versatile relief valve has no orientation restrictions during installation and supports various seal kits for maintenance flexibility.
