The Hydraforce 5621461.27 (5621461.27) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve operates by initially blocking flow from port 2 to port 3 in its steady state. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber venting at port 3 allows back pressure to influence the valve setting directly on a 1:1 ratio basis. If pressure at port 1 falls below the set reload value, based on fixed unload/reload pressure ratios of either 60%, 70%, or 80%, the valve will close and block flow again from port 2 to port 3. Notable features include adjustments that cannot be backed out of the valve and adjustments that prevent springs from becoming solid. Optional spring ranges extend up to 207 bar (3000 psi), ensuring versatile application capabilities. Additionally, the hardened spool and cage contribute to extended durability and reliability, while its industry-common size facilitates easy integration into existing systems.
