The Hydraforce RV12-26H-0-N-35/25 (Material Number: 5623404.25) 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 that require rapid response and low hysteresis. This valve effectively blocks flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to activate the pilot relief, allowing the main stage to open and release pressure. It is important to note that this valve is not suitable for cross-over relief applications. Key features include non-backable adjustments, preventing springs from becoming solid, and a hardened spool and cage for enhanced durability. The valve offers optional spring ranges up to 240 bar (3500 psi) and ensures rapid, smooth responses to pressure surges. The RV12-26H-0-N-35/25 has a maximum flow rating of 170.3 lpm (45 gpm) at maximum pressure and can handle internal leakage up to 197 ml/min (12 in\u00b3/min) at port 2 when set at 85% of nominal setting. It operates within an extensive temperature range depending on seal choice: -40\u00b0C to 100\u00b0C with Buna N seals, -26\u00b0C to 204\u00b0C with fluorocarbon seals, and -54\u00b0C to 107\u00b0C with polyurethane seals. The valve also meets rigorous corrosion protection standards withstanding up to 960 hours of salt spray per ASTM B117. Installation requires a VC12-2 cavity with specified torque settings, ensuring proper fitment without orientation restrictions. The unit's wetted surface area varies between models but generally falls between 209 cm\u00b2 and 221 cm\u00b2. For maintenance or replacement needs, seal kits are available under SK12-2X-B designation based on seal options chosen during installation.
