The Hydraforce 5621406 (5621406) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the valve 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 valve's spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the reload value set by the chosen ratio, the valve will close again, blocking flow from port 2 to port 3. Key features include non-backout adjustments and springs that are designed not to go solid, ensuring consistent performance and durability. The valve can handle optional spring ranges up to 207 bar (3000 psi), and it features a hardened spool and cage for extended life. Additionally, its design adheres to industry-common sizes for ease of integration into existing systems.
