The Hydraforce RV12-26H-0-N-04/03.5 (Material Number: 5623400.03.5) is a screw-in, cartridge-style, pilot-operated, spool-type relief valve designed to act as a pressure-limiting device in demanding hydraulic circuits requiring fast response and low hysteresis. This two-stage valve operates by blocking flow from port 1 to port 2 until adequate pressure at port 1 forces the pilot relief off its seat, allowing the main stage to shift and open the path between the ports. It is not suitable for cross-over relief applications. The valve features adjustments that cannot be backed out, preventing springs from going solid, and includes a hardened spool and cage for enhanced durability. It offers optional spring ranges up to 240 bar (3500 psi) with rapid and smooth response to pressure surges. The RV12-26H-0-N-04/03.5 has a pressure rating of 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof pressure rated at 689.5 bar (10000 psi) and burst pressure at 1379 bar (20000 psi). It is designed to handle flow rates up to 170.3 lpm (45 gpm) at maximum pressure, with internal leakage limited to 197 ml/min at port 2 when set at nominal conditions. This valve can operate within fluid temperature ranges of -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. It demonstrates excellent corrosion resistance withstanding up to 960 hours in salt spray per ASTM B117 standards. Installation requires a VC12-2 cavity with torque settings between 44.7 to 50.2 N-m for standard installations or slightly lower for H-style plugs, ensuring versatility across various hydraulic systems without orientation restrictions.
