The Hydraforce RVD50-20H-0-N-42 (Material Number: 5612509) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for pressure limiting in hydraulic circuit protection. It efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, offering rapid response to load changes with minimal hysteresis, pressure rise, and internal leakage. This valve features a hardened poppet and cage for durability and includes optional spring ranges up to 345 bar (5000 psi). It is built with an industry-common cavity and ensures that adjustments cannot be unintentionally backed out. The RVD50-20H-0-N-42 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). It demonstrates a crack pressure defined at 0.95 lpm (0.25 gpm) with a reseat pressure nominally at 85% of the crack pressure. This relief valve supports flow rates up to 113.6 lpm (30 gpm) from port 1 to port 2 at maximum pressure, with internal leakage capped at 0.25 ml/min (5 drops/min). It operates effectively across fluid temperatures ranging from -40 to +100 \u00b0C (-40 to +212 \u00b0F) with buna N seals and can withstand storage temperatures between -40 and +70 \u00b0C (-40 and +160 \u00b0F). The valve's corrosion protection meets the ASTM B117 standard for up to 960 hours in salt spray conditions, making it suitable for harsh environments. The RVD50-20H-0-N-42 accommodates fluid viscosities between 7.4 to 420 cSt and maintains optimal performance within an operating contamination level of ISO 4406 code:18/16/13. This unit weighs approximately between 0.20 kg (0.44 lb) and has an internal wetted surface area of either 158 cm\u00b2 or less depending on configuration details provided by its manufacturer specifications.
