The Hydraforce RVD50-20A-0-N-32 (5612563) is a robust screw-in, cartridge-style, direct-acting poppet-type relief valve designed for effective pressure limiting in hydraulic circuit protection. It operates by blocking flow from port 1 to port 2 until sufficient pressure at port 1 forces the poppet off its seat. This valve is engineered for quick response to load changes, featuring low hysteresis, minimal pressure rise, and low internal leakage. It boasts a hardened poppet and cage for extended durability and offers optional spring ranges up to 345 bar (5000 psi). The RVD50-20A-0-N-32 has 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). Its crack pressure is defined at a flow rate of 0.95 lpm (0.25 gpm), with nominal reseat pressure at 85% of the crack pressure. The valve accommodates a flow rating of up to 113.6 lpm (30 gpm) from port 1 to port 2 under maximum pressure conditions, with maximum internal leakage limited to 0.25 ml/min (5 drops/min) at up to 80% nominal capacity. It operates efficiently across various temperature ranges 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. With corrosion protection rated for up to 960 hours in salt spray per ASTM B117 standards, it supports fluids that are mineral-based or synthetic with lubricating properties within a viscosity range of 7.4 to 420 cSt. The cartridge installation torque is specified between 63.7 and 71.9 N-m (47 to 53 ft-lb), fitting into industry-standard VC10-2 cavities without orientation restrictions. Optional seal kits and housings are available for customized application needs.
