The Hydraforce RV10-26A-0-N-04 (5613005) is a high-performance, screw-in, cartridge-style hydraulic relief valve designed for demanding hydraulic circuits that require rapid response and low hysteresis. This pilot-operated, two-stage spool type valve effectively limits pressure by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to activate the piloting relief, allowing the main spool to shift and open the flow path. It features a hardened spool and cage for enhanced durability and offers adjustment options with positive stops to prevent spring solidification. The valve provides optional spring ranges up to 207 bar (3000 psi) and operates smoothly under pressure surges. It fits into industry-common cavities, specifically VC10-2 or 10-size-2-way cavities, with an installation torque of 33.9 to 36.7 N-m (25 to 27 ft-lb). The RV10-26A-0-N-04 has a pressure rating of up to 241 bar (3500 psi), proof pressure of 517.1 bar (7500 psi), and burst pressure of 1037.7 bar (15000 psi). Its maximum flow rating is 113.6 lpm (30 gpm) at max pressure, with internal leakage rates contingent on specific conditions. The operational temperature range varies depending on seal material, accommodating environments from -54\u00b0C to 204\u00b0C (-65\u00b0F to 400\u00b0F). This valve requires mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains an operating contamination level per ISO standards at 18/16/13. Additional accessories include various seal kits and housings available for customization needs, ensuring comprehensive functionality in diverse applications while adhering strictly to its intended use as a pressure-limiting device without cross-over relief capabilities.
