The Hydraforce RV12-26A-12T-N-35/ (Material Number: 5623084) is a screw-in, cartridge-style, pilot-operated (two-stage), spool-type relief valve designed for use as a pressure-limiting device in demanding hydraulic circuits requiring fast response and low hysteresis. This valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to force the pilot relief off its seat, allowing the main stage to shift and open port 1 to port 2. Notably, this valve is unsuitable for cross-over relief applications. Key features include non-backable adjustments, prevention of springs going solid, and a hardened spool and cage for extended longevity. The valve offers optional spring ranges up to 240 bar (3500 psi) and ensures rapid, smooth responses to pressure surges. The RV12-26A-12T-N-35/ has a maximum pressure rating of 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof pressure reaching up to 689.5 bar (10,000 psi) and burst pressure at an impressive 1379.0 bar (20,000 psi). It can handle flow rates up to 170.3 lpm (45 gpm) at maximum pressure with an internal leakage of up to 197 ml/min at specified conditions. Temperature ratings vary based on seal type: -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 offers robust corrosion protection withstanding up to 960 hours of salt spray per ASTM B117 standards. Installation requires a VC12-2 cavity with specific torque settings depending on the plug style used. The product supports mineral-based or synthetic fluids within a viscosity range of 7.4 to 420 cSt and maintains optimal performance under contamination levels as per ISO standards.
