The Hydraforce 5621400.M180 (5621400.M180) 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 features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it blocks flow from port 2 to port 3. When a specified pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber venting at port 3 means that any back pressure directly affects the valve setting with a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve will close again, blocking flow from port 2 to port 3. The UP10-31 includes features such as non-backable adjustments and springs designed to avoid going solid. It offers optional spring ranges up to 207 bar (3000 psi) and is built with a hardened spool and cage for enhanced longevity. Additionally, it comes in an industry-common size for easier integration into existing systems.
