The Hydraforce RV10-26A-8T-N-04/ (5613065) is a screw-in, cartridge-style, pilot-operated, two-stage spool type hydraulic relief valve designed for use as a pressure limiting device in demanding hydraulic circuits requiring fast response and low hysteresis. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the piloting relief, allowing the main spool to shift and open the flow path. Notably, this valve is not suitable for cross-over relief applications. Key features include non-backout adjustments with positive stops on options A, B, and C to prevent spring solidification, and a hardened spool and cage for enhanced durability. It offers optional spring ranges up to 207 bar (3000 psi) and ensures a fast, smooth response to pressure surges. The valve fits into an industry-common cavity VC10-2. The RV10-26A-8T-N-04/ can handle a maximum pressure rating of 241 bar (3500 psi), with proof pressure up to 517.1 bar (7500 psi) and burst pressure reaching 1037.7 bar (15000 psi). Its flow rating stands at 113.6 lpm (30 gpm) at maximum pressure, while internal leakage is maintained at specified levels depending on the pressure setting relative to crack pressure. Operating fluid temperature ranges vary based on seal material: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. The valve also features corrosion protection withstanding up to 960 hours of salt spray per ASTM B117 standards. It supports mineral-based or synthetic fluids within a viscosity range of 7.4 to 420 cSt and maintains an operating contamination level of ISO 4406 standard of 18/16/13. Installation specifications include cartridge installation torque between 33.9 N-m (25 ft-lb) and maximum allowable torque of up to 66.7 N-m (50 ft-lb).
