The Hydraforce RVD50-20C-0-N-15/ (5612579N) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection by acting as a pressure limiting device. This valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is high enough to displace the poppet off its seat, ensuring rapid response to load changes with minimal hysteresis, low pressure rise, and reduced internal leakage. Notable features include non-backable adjustments and a stable adjuster height during pressure setting modifications. The valve's hardened poppet and cage enhance its durability, and it offers optional spring ranges up to 345 bar (5000 psi). It fits an industry-common cavity size VC10-2 and requires an installation torque of 63.7 to 71.9 N-m (47 to 53 ft-lb). The RVD50-20C-0-N-15/ operates under a maximum pressure rating of 413.7 bar (6000 psi), with proof and burst pressures at 785.4 bar (11000 psi) and 1515.8 bar (22000 psi), respectively. Its crack pressure becomes noticeable at a flow rate of 0.95 lpm (0.25 gpm), while reseat pressure is nominally set at 85% of crack pressure with maximum internal leakage capped at 0.25 ml/min (5 drops/min) up to 80% of nominal flow rating of 113.6 lpm (30 gpm). The valve can withstand operating fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) for buna N seals, extending further for other seal types like fluorocarbon or polyurethane. This relief valve also provides excellent corrosion protection withstanding up to 960 hours in salt spray per ASTM B117 standards and supports fluid viscosities from 7.4 to 420 cSt while maintaining operational integrity within contamination levels defined by ISO standards at an impressive unit weight range depending on configuration specifics.
