The Hydraforce RV12-26B-16T-N-35/ (Material Number: 5623194) is a screw-in, cartridge style, pilot operated (two-stage), spool type relief valve designed for pressure limiting in demanding hydraulic circuits. This model blocks flow from port 1 to port 2 until sufficient pressure at port 1 triggers the pilot relief, allowing the main stage to open and facilitate flow. The valve features adjustments that prevent springs from becoming solid and cannot be backed out of the valve. It is equipped with a hardened spool and cage for enhanced durability and offers optional spring ranges up to 240 bar (3500 psi). With rapid and smooth responses to pressure surges, it is an efficient solution for hydraulic applications requiring fast response and low hysteresis. The RV12-26B-16T-N-35/ has a pressure rating of up to 241.3 bar (3500 psi) at port 1 and up to 103.4 bar (1500 psi) at port 2, with proof pressure standing at 689.5 bar (10000 psi) and burst pressure at 1379.0 bar (20000 psi). It can handle a flow rate of up to 170.3 lpm (45 gpm) at maximum pressure while maintaining internal leakage below 197 ml/min (12 in\u00b3/min) at port 2 under specified conditions. This relief valve operates effectively within fluid temperatures ranging from -40\u00b0C to +204\u00b0C depending on seal material, with storage temperatures between -40\u00b0C and +70\u00b0C. It is compatible with mineral-based or synthetic fluids having lubricating properties within a viscosity range of 7.4 to 420 cSt, maintaining an operating contamination level of ISO class 18/16/13. Installation specifications include a VC12-2 cavity requirement with cartridge installation torque ranging from 44.7 to 50.2 N-m for standard applications or slightly lower for H-style plugs. The unit's corrosion protection withstands up to 960 hours of salt spray per ASTM B117 standards, ensuring reliability in harsh environments.
