The Hydraforce RVD50-20A-0-P-32 (5612563P) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection as a pressure limiting device. This valve efficiently 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 that maintains adjuster height regardless of pressure setting changes. Constructed with a hardened poppet and cage, it ensures long-lasting durability. It offers optional spring ranges up to 345 bar (5000 psi) and can handle pressures up to 413.7 bar (6000 psi), with proof and burst pressures rated at 785.4 bar (11000 psi) and 1515.8 bar (22000 psi), respectively. The RVD50-20A-0-P-32 has a flow rating of 113.6 lpm (30 gpm) from port 1 to port 2 at maximum pressure while maintaining maximum internal leakage of only 0.25 ml/min (5 drops/min). It operates effectively across a wide temperature range with various seal options: -40 to 100 \u00b0C (-40 to 212 \u00b0F) for Buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) for fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) for both polyurethane and urethane seals. The valve can also withstand storage and ambient temperatures from -40 to 70 \u00b0C (-40 to 160 \u00b0F). Corrosion protection is ensured with a rating of up to 960 hours in salt spray per ASTM B117 standards. Compatible with mineral-based or synthetic fluids possessing lubricating properties, the RVD50-20A-0-P-32 supports a fluid viscosity range from 7.4 to 420 cSt and maintains an operating contamination level of ISO code cleanliness standard of up to ISO4406:18/16/13. The unit weighs between approximately 0.20 kg (0.44 lb) and has an internal wetted surface area ranging from about 151 cm\u00b2 (23.3 in\u00b2). Installation requires VC10-2 cavity compatibility with cartridge installation torque specified between 63.7 and 71.9 N-m (47 and 53 ft-lb). Seal kits are available for maintenance needs under different part numbers based on the seal type required.
