The Hydraforce 5621440.M140 (5621440.M140) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-31, this valve 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, so any back pressure directly affects the valve setting on a 1:1 basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes, blocking flow again between ports 2 and 3. The design features adjustments that cannot be backed out of the valve and prevent springs from going solid, ensuring durability and reliability. It offers optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for extended lifespan. This component is designed with an industry-common size for easy integration into existing systems.
