The Hydraforce 5621401.15 (Material Number: 5621401.15) is a 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 default state, it blocks flow from port 2 to port 3. Upon reaching a predetermined pressure 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 directly affects the valve setting at a ratio of 1:1. If the pressure at port 1 decreases below the established reload value, the valve closes, preventing flow from port 2 to port 3 once again. This product features adjustments that cannot be backed out of the valve and prohibits springs from going solid, ensuring reliability and durability in operation. It offers optional spring ranges up to 207 bar (3000 psi), and its hardened spool and cage contribute to a long service life. Additionally, it is an industry-common size, making it versatile for various applications within hydraulic systems requiring precise control of fluid flow based on pressure conditions.
