The Hydraforce RV12-26A-12T-N-04 (Material Number: 5623080) is a screw-in, cartridge-style, pilot-operated, two-stage spool type relief valve designed for pressure-limiting applications in demanding hydraulic circuits. This model is characterized by its fast response and low hysteresis, making it ideal for systems requiring rapid adjustments to pressure surges. The valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to activate the pilot relief, allowing the main stage to open and relieve the pressure. Notably, this valve is not suitable for cross-over relief applications. Key features include non-backable adjustments that prevent springs from going solid and a hardened spool and cage that ensure long life. It offers optional spring ranges up to 240 bar (3500 psi). The RV12-26A-12T-N-04 withstands a maximum pressure rating of 241.3 bar (3500 psi) at port 1 and has proof and burst pressures of 689.5 bar (10000 psi) and 1379.0 bar (20000 psi), respectively. It supports a flow rating of up to 170.3 lpm (45 gpm) at maximum pressure, with an internal leakage rate of up to 197 ml/min at port 2 under specific conditions. Temperature ratings vary based on seal material, accommodating operating fluid temperatures ranging from -54\u00b0C to 204\u00b0C depending on the seal type used. This model also boasts corrosion protection withstanding up to 960 hours in salt spray tests per ASTM B117 standards and requires mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt for optimal performance. Installation specifications include compatibility with VC12-2 cavities and specific torque requirements for cartridge installation.
