The Hydraforce 5621400.25 (5621400.25) 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 flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting on a 1:1 basis. If the pressure at port 1 falls below the established reload value ratio, the valve will close and block flow from port 2 to port 3 again. This product features adjustments that cannot be backed out of the valve and prohibits springs from becoming solid, ensuring reliability and consistent performance. It also offers optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage contribute to its long life and durability, making it an industry-common size suitable for various applications requiring precise hydraulic control in accumulator systems.
