The Hydraforce 5621442 (5621442) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This model, known as the UP10-31, features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure there will have a direct (1:1) impact on the valve setting. Should the pressure at port 1 fall below the established reload value ratio, the valve will close to block flow from port 2 to port 3 again. Key features include non-reversible adjustments that prevent springs from going solid and optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage enhance durability and longevity, while its industry-common size ensures compatibility with various systems.
