The Hydraforce 5621403.15 (5621403.15) 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 default state, the UP10-31 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the valve's spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning any back pressure here will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value ratio, the valve closes again, preventing flow from port 2 to port 3. Key features of this model include adjustments that cannot be backed out of the valve and adjustments that prevent springs from becoming solid. It also offers optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage ensure long-lasting performance, and its industry-common size allows for easy integration into existing systems.
