The Hydraforce RVD50-20A-0-P-08 (5612562P) is a robust screw-in, cartridge-style, direct-acting poppet type relief valve designed for effective hydraulic circuit protection. This relief valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, thereby ensuring precise pressure control. Notable for its rapid response to pressure changes, it boasts low hysteresis, low pressure rise, and minimal internal leakage. The valve's construction features a hardened poppet and cage for enhanced durability and longevity. It offers optional spring ranges up to 345 bar (5000 psi) and maintains a consistent adjuster height during pressure adjustments. The RVD50-20A has impressive ratings with a maximum pressure rating of 413.7 bar (6000 psi), proof pressure of 785.4 bar (11000 psi), and burst pressure reaching up to 1515.8 bar (22000 psi). It operates effectively with mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. The valve's 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 resilience is another key feature, with operating fluid temperatures ranging from -40 to 100 \u00b0C with buna N seals and extending up to -54 to 107 \u00b0C with polyurethane or urethane seals. The valve also withstands ambient temperatures between -40 and 70 \u00b0C and provides corrosion protection for up to 960 hours in salt spray conditions per ASTM B117 standards. Weighing between 0.20 kg and 0.25 kg depending on configuration, the RVD50-20A installs in VC10-2 cavities requiring a torque range of 63.7 to 71.9 N-m for secure installation without orientation restrictions, making it versatile across various applications requiring reliable hydraulic circuit protection.
