The Hydraforce RV08-20H-0-N-33/28.5 (5600409.28.5) is a screw-in, cartridge-style, direct-acting poppet type hydraulic relief valve designed for lower flow circuits with minimal internal leakage. This valve effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to move the spring-opposed poppet off its seat. It features a variety of pressure adjustment options, including non-adjustable factory presets and optional spring ranges up to 248 bar (3600 psi). The valve offers rapid response to pressure changes and can accommodate bi-directional pressure when equipped with the appropriate bi-directional pressure seal option. Compact in size, it is rated for pressures up to 482.6 bar (7000 psi) and can withstand burst pressures up to 896.3 bar (13000 psi). The flow rating is set at a maximum of 22.7 lpm (6 gpm) at peak pressure, with internal leakage limited to 0.25 ml/min (5 drops/min) at up to 75% of its nominal setting. Operating fluid temperature ranges vary based on seal materials: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with urethane seals. It supports mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains an operating contamination level of ISO 4406:18/16/13. The RV08-20H-0-N-33/28.5 requires a VC08-2 cavity for installation and can be torqued between 25.8 to 28.5 N-m (19 to 21 ft-lb), with a maximum allowable torque of 40.7 N-m (30 ft-lb). Seal kits such as SK08-2X-B are available for maintenance needs, ensuring reliable performance in various hydraulic applications requiring precise pressure control and low leakage characteristics.
