The Hydraforce RVD58-20C-0-P-50/38 (5612917.38) is a screw-in, cartridge-style, direct-acting poppet type relief valve designed for hydraulic circuit protection as a pressure-limiting device. This compact and economical valve 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 and internal leakage. It features a hardened poppet and cage for enhanced durability, with optional spring ranges up to 350 bar (5076 psi). The valve supports high durometer Buna, Fluorocarbon, and Polyurethane seals for diverse applications. Pressure ratings include 350 bar at port 1 and 207 bar at port 2, with proof pressure up to 413 bar and burst pressure reaching 1379 bar. It has a flow rating of up to 37.9 lpm from port 1 to port 2 at maximum pressure and maintains minimal internal leakage of just 0.25 ml/min under maximum conditions. The RVD58-20 operates efficiently across a wide range of temperatures: -40\u00b0C to 100\u00b0C with Buna N seals, -26\u00b0C to 204\u00b0C with Fluorocarbon seals, and -54\u00b0C to 107\u00b0C with Polyurethane seals. It also withstands ambient temperatures between -40\u00b0C and 70\u00b0C during operation or storage. The unit weighs approximately 0.13 kg and exhibits an internal wetted surface area of about 89 cm\u00b2. For installation, the VC08-2B cavity is required, with an installation torque range of 44.7 to 50.2 N-m for the cartridge itself. Adjuster torque should not exceed 17.6 N-m when backing out the adjuster, while the locknut torque is specified at approximately \u00b113 N-m. The RVD58-20 comes equipped with corrosion protection rated for up to 230 hours in salt spray per ASTM B117 standards and can handle fluid viscosities ranging from 7.4 to over420 cSt while maintaining cleanliness levels per ISO4406 standards.
