The Hydraforce 5621401.08.5 (5621401.08.5) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, at which point the spool shifts to permit flow from port 2 to port 3. The valve's setting is directly affected by back pressure at port 3 due to the spring chamber being vented there in a direct (1:1) ratio. If the pressure at port 1 falls below the established reload value ratio, the valve will close and block flow once again from port 2 to port 3. This product includes features such as non-backout adjustments, which prevent springs from going solid and optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage are engineered for durability and longevity, making it suitable for demanding applications where reliability is crucial. Additionally, its industry-common size allows for easier integration into existing systems.
