The Hydraforce RV08-20A-0-NC-18 (5600007) is a direct acting, poppet type hydraulic relief valve, designed as a screw-in, cartridge style unit. This valve is particularly suited for lower flow circuits that require minimal internal leakage. It operates by blocking 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 reliable operation and control. The RV08-20A-0-NC-18 features various pressure adjustment options, including non-adjustable factory presets, with positive stops to prevent springs from going solid and optional spring ranges up to 248 bar (3600 psi). This model responds rapidly to changes in pressure and can be equipped with a bidirectional pressure seal option if needed. Its compact size enhances its suitability for space-constrained applications. This model has specific pressure ratings with a maximum of 482.6 bar (7000 psi), and burst pressure capabilities up to 896.3 bar (13000 psi). The relief pressures are well-defined, providing precise control over system pressures at low flows around 0.95 lpm (0.25 gpm). Additionally, the reseat pressure is nominally set at 80% of the crack pressure. Flow characteristics are also notable; it supports up to 22.7 lpm (6 gpm) at maximum pressure settings with very low internal leakage not exceeding 0.25 ml/min (5 drops/min). Temperature adaptability ranges from -40°C to +100°C (-40°F to +212°F) depending on seal material, making it versatile across different operating environments. For installation, this valve uses an VC082 cavity and can be installed without orientation restrictions, offering flexibility in system design. The RV08-20A-0-NC-18 also supports a range of fluids including mineral-based or synthetic types with lubricating properties within a viscosity range of 7.4 to 420 cSt. In summary, the Hydraforce RV08-20A-0-NC-18 offers robust performance for hydraulic systems requiring high reliability and precise pressure management in compact spaces.
