The Hydraforce 5621401.M125 (5621401.M125) is a versatile screw-in, cartridge-style remote sequence pilot unloading valve designed for 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 default state, it blocks flow from port 2 to port 3. Upon reaching a specified pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber's venting at port 3 means that any back pressure here will directly affect the valve setting at a 1:1 ratio. If the pressure at port 1 falls below the established reload value ratio, the valve closes and blocks flow again. Key features include adjustments that cannot be backed out of the valve and are designed to prevent springs from becoming solid. The valve supports optional spring ranges up to 207 bar (3000 psi) and is constructed with hardened spools and cages for enhanced durability. Its industry-common size makes it adaptable for various applications in hydraulic systems.
