The Hydraforce 5621407 (5621407) 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, offers 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 from port 2 to port 3. The spring chamber is vented at port 3, meaning that any back pressure at this port directly affects the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes and blocks flow from port 2 to port 3 again. The UP10-31 features adjustments that cannot be backed out of the valve and prohibits springs from going solid, ensuring reliability and consistent performance. It also offers optional spring ranges up to 207 bar (3000 psi), with hardened spool and cage components for enhanced durability and long life. Its industry-common size ensures compatibility with a wide range of systems and applications where precise hydraulic control is required.
