The Hydraforce RV12-26C-0-N-35/ (Material Number: 5623204) 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 requiring fast response and low hysteresis. This relief valve efficiently blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to force the pilot relief off its seat, causing the main stage to shift and open port 1 to port 2. Notably, this valve is not suitable for cross-over relief applications. It features adjustments that prevent backing out of the valve and prohibit springs from going solid, enhancing durability with a hardened spool and cage. The RV12-26C offers optional spring ranges up to 240 bar (3500 psi) and provides rapid, smooth responses to pressure surges. Its pressure ratings include a maximum of 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof pressures reaching up to 689.5 bar (10000 psi) and burst pressures up to 1379.0 bar (20000 psi). The valve supports flow rates of up to 170.3 lpm (45 gpm) at maximum pressure with minimal internal leakage of 197 ml/min at port 2 under specific conditions. It operates across a wide range of temperatures depending on the seal type used, making it versatile for various environments. Additionally, it boasts significant corrosion protection withstanding up to 960 hours in salt spray per ASTM B117 standards. The RV12-26C accommodates mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt while maintaining optimal performance under specified contamination levels as per ISO standards.
