The Hydraforce RV10-20A-0-N-33/28 (5610003.28) is a screw-in, cartridge-style, direct-acting, poppet-type hydraulic relief valve. This component is designed to function as a pressure-limiting device, ensuring protection for standard hydraulic circuits. It is compatible with both mineral-based and synthetic hydraulic fluids that possess lubricating properties. The RV10-20A operates by blocking flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to unseat the poppet, allowing for quick response to load changes while maintaining low internal leakage. This relief valve is capable of handling pressure ratings up to 228 bar (3300 psi) at port 1 and 34.5 bar (500 psi) at port 2, with proof and burst pressures reaching 517.1 bar (7500 psi) and 1037.7 bar (15000 psi), respectively. Its crack pressure is defined at a flow of 0.95 lpm (0.25 gpm), with reseat pressure nominally set at 85% of crack pressure. The relief pressure range extends from 6.9 to 206.8 bar (100 to 3000 psi). In terms of flow capacity, the valve can handle up to 38 lpm (10 gpm) at maximum pressure, while maintaining a maximum internal leakage rate of just five drops per minute. Temperature ratings for operation vary depending on seal material: -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 polyurethane seals. The valve features Type III clear zinc plating per ASTM B633 for corrosion protection and fits into VC10-2 cavities requiring an installation torque between 33.9 and 36.7 N-m (25 to 27 ft-lb). With no orientation restrictions, this versatile relief valve ensures reliable performance across various applications.
