The Hydraforce RVD50-20A-0-P-50 (5612565P) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection as a pressure-limiting device. It effectively blocks flow from port 1 to port 2 until a specific pressure at port 1 forces the poppet off its seat, ensuring rapid response to load changes with low hysteresis and minimal internal leakage. This valve features a hardened poppet and cage for extended durability, adjustable settings that do not alter the adjuster's height, and optional spring ranges up to 345 bar (5000 psi). It is rated for pressures up to 413.7 bar (6000 psi), with proof pressure at 785.4 bar (11000 psi), and burst pressure at 1515.8 bar (22000 psi). The crack pressure is defined as evident at 0.95 lpm (0.25 gpm), with a reseat pressure nominally at 85% of the crack pressure. The valve supports flow rates up to 113.6 lpm (30 gpm) from port 1 to port 2 at maximum pressure, with internal leakage maintained at or below 0.25 ml/min (5 drops/min) to 80% of nominal capacity. It operates efficiently across various temperature ranges depending on seal type: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with both polyurethane and urethane seals. Storage and ambient temperatures range from -40 to 70 \u00b0C. Designed for use in VC10-2 cavities with no orientation restrictions, the RVD50-20A-0-P-50 can be installed using torque values between 63.7 and 71.9 N-m (47 to 53 ft-lb). Compatible fluids include mineral-based or synthetic types with lubricating properties within a viscosity range of 7.4 to 420 cSt, while maintaining contamination levels as per ISO standards. Seal kits are available in various configurations for different applications.
