The Hydraforce RV08-20B-0-N-18 (5600102) is a direct acting, poppet type hydraulic relief valve cartridge, designed for low flow circuits with a need for minimal internal leakage. This model effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to displace the spring-opposed poppet from its seat, ensuring precise pressure control. The valve offers multiple pressure adjustment options including non-adjustable factory presets and adjustments options A, B, and C with positive stops that prevent springs from going solid. It also supports optional spring ranges up to 248 bar (3600 psi) and can respond rapidly to changes in pressure. This compact unit features an optional bidirectional pressure seal option enhancing its application versatility in various hydraulic systems. Notably, the RV08-20B-0-N-18 is designed to ensure reliability and durability with maximum internal leakage maintained at just 0.25 ml/min (5 drops/min) up to 75% of its nominal setting. It operates efficiently within a temperature range of -40°C to +100°C with Buna N seals and can handle fluid viscosities ranging from 7.4 to 420 cSt. The valve fits into a standard VC082 cavity and requires specific installation torque, ensuring secure fitting without orientation restrictions. Its robust design allows it to withstand high operating pressures up to 482.6 bar (7000 psi) and burst pressures up to 896.3 bar (13000 psi), making it an ideal choice for demanding applications requiring reliable relief functions in compact hydraulic systems.
