The Hydraforce 5621441 (5621441) 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 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. When a predetermined pressure is reached at port 1, the spool shifts to enable flow from port 2 to port 3. The spring chamber is vented at port 3, meaning any back pressure here will directly affect the valve setting at a ratio of 1:1. If the pressure at port 1 falls below the established reload value, the valve closes again, stopping flow from port 2 to port 3. Notable features include adjustments that cannot be backed out and mechanisms that prevent springs from becoming solid. The UP10-31 offers optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for enhanced durability. It also conforms to industry-common sizes for ease of integration into existing systems.
