The Hydraforce RV12-26A-0-N-30/16 (Material Number 5623006.16) is a screw-in, cartridge-style, pilot-operated spool type relief valve designed for use as a pressure limiting device in demanding hydraulic circuits. This two-stage valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to lift the pilot relief, allowing the main stage to shift and open the flow path. Notably, this valve is not suitable for cross-over relief applications. Key features include adjustments that cannot be backed out of the valve, preventing springs from going solid, and a hardened spool and cage for extended lifespan. The valve offers optional spring ranges up to 240 bar (3500 psi) and provides rapid, smooth responses to pressure surges. In terms of ratings, the RV12-26A has a pressure rating of 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof and burst pressures of 689.5 bar (10000 psi) and 1379.0 bar (20000 psi), respectively. The flow rating reaches up to 170.3 lpm (45 gpm) at maximum pressure with internal leakage limited to 197 ml/min at port 2 under nominal settings. The operating fluid temperature varies depending 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. It can withstand storage temperatures from -40 to 70 \u00b0C and offers corrosion protection withstanding up to a 960-hour salt spray per ASTM B117 standards. Installation specifications include a VC12-2 cavity requirement with cartridge installation torque ranging from 44.7 to 50.2 N-m or slightly less for H-style plugs. Seal kits are available under part number SK12-2X-B based on seal options chosen, ensuring adaptability in various applications requiring robust hydraulic solutions.
