The Hydraforce 5621401.26 (5621401.26) is a versatile screw-in, cartridge-style remote sequence pilot unloading valve designed for use in 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 permit flow between these ports. The spring chamber's venting at port 3 ensures that any back pressure directly affects the valve setting on a 1:1 basis. Should the pressure at port 1 fall below the established reload value, determined by the chosen ratio, the valve will close and block flow from port 2 to port 3 again. Key features include adjustments that cannot be backed out of the valve and are designed to prevent springs from going solid, ensuring durability and reliability. The UP10-31 also boasts optional spring ranges up to 207 bar (3000 psi), with hardened spool and cage components for extended life. Its industry-common size allows for seamless integration into existing hydraulic systems where precise control of fluid flow is essential.
