The Hydraforce RVD58-20A-0-N-30 (5612904) is a compact, screw-in, cartridge-style relief valve designed as a pressure limiting device for hydraulic circuit protection. This direct-acting poppet type valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the poppet, providing fast response to load changes with low hysteresis and minimal internal leakage. The valve features hardened poppet and cage components for extended durability and offers optional spring ranges up to 350 bar (5076 psi). It has a proof pressure of 413 bar (10,000 psi) and a burst pressure of 1379 bar (20,000 psi) at port 1. The RVD58-20 operates effectively within an ambient temperature range of -40 to 70 \u00b0C (-40 to 160 \u00b0F), with seals available in Buna N, fluorocarbon, or polyurethane for varied operating fluid temperatures. The valve supports fluid viscosities from 7.4 to 420 cSt and maintains optimal performance with mineral-based or synthetic fluids possessing lubricating properties. It achieves a flow rating of up to 37.9 lpm (10 gpm) from port 1 to port 2 at maximum pressure while ensuring maximum internal leakage does not exceed 0.25 ml/min (5 drops). Installation specifications include compatibility with VC08-2B cavities and an installation torque range of 44.7 to 50.2 N-m (33 to 37 ft-lb). The unit weighs approximately 0.13 kg (0.28 lb) and includes a high durometer seal kit option for enhanced sealing capabilities under various conditions. Accessories such as tamper-proof caps are available for added security in applications where adjustments should be restricted post-installation.
