The Hydraforce 5621401.M141 (5621401.M141) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for 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. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning any back pressure here directly affects the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value according to the set ratio, the valve closes to block flow again from port 2 to port 3. This design ensures that adjustments cannot be backed out of the valve and prevents springs from going solid. It offers optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for enhanced durability. The UP10-31 also comes in an industry-common size for ease of integration into existing systems.
