The Hydraforce RV08-20A-0-N-18 (5600002) is a precision-engineered relief valve cartridge, specifically designed for hydraulic applications requiring reliable low-flow control and minimal internal leakage. This direct-acting, poppet-type valve ensures effective blockage of flow from port 1 to port 2 until a predefined pressure threshold prompts the spring-opposed poppet to disengage from its seat, allowing fluid passage. Key features of the RV08-20A-0-N-18 include a range of pressure adjustment options—from non-adjustable factory presets to configurations with positive stops that prevent springs from going solid—supporting various application needs. It offers optional spring ranges up to 248 bar (3600 psi) and is responsive to rapid changes in pressure. For systems requiring bidirectional pressure control, an appropriate seal option can be incorporated, enhancing versatility. The compact design of this valve makes it suitable for installation in space-constrained environments while maintaining high performance and reliability. Pressure ratings for this model include operational pressures up to 482.6 bar (7000 psi) and a burst pressure reaching 896.3 bar (13000 psi). It also features maximum internal leakage limited to only 0.25 ml/min at 75% of the nominal setting, ensuring efficient operation. Temperature resilience is another notable characteristic, with operating fluid temperatures ranging from -40°C to +100°C depending on the seal material used—buna N, fluorocarbon, or urethane seals. The RV08-20A-0-N-18 operates effectively within a broad viscosity range of 7.4 to 420 cSt and can handle maximum operating contamination levels as specified by ISO standards. This valve's robust construction and adaptable features make it an essential component for sophisticated hydraulic systems demanding precise pressure relief and flow control capabilities.
