The Hydraforce 5621460 (5621460) is a screw-in, cartridge-style remote sequence pilot unloading valve, designed specifically 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 steady state, the UP10-31 blocks the flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to permit flow from port 2 to port 3. The spring chamber venting at port 3 means that any back pressure at this point will directly affect the valve setting in a one-to-one ratio. If the pressure at port 1 falls below the established reload value, the valve will close and block flow again from port 2 to port 3. Notable features include adjustments that cannot be backed out of the valve and are designed to prevent springs from becoming solid. The UP10-31 also supports optional spring ranges up to 207 bar (3000 psi), with a hardened spool and cage for enhanced durability and longevity. This component is sized according to industry standards, facilitating easy integration into various systems.
