The Hydraforce 5621400.11.5 (5621400.11.5) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically 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 steady state, it effectively blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, which then shifts the spool to permit flow between these ports. The vented spring chamber at port 3 ensures that any back pressure directly affects the valve setting in a precise 1:1 ratio. Should the pressure at port 1 fall below the established reload value, the valve automatically closes to block flow once again between ports 2 and 3. Notable features of this model include adjustments that cannot be backed out of the valve and prohibitions on springs going solid, ensuring reliability and longevity in performance. It supports optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for extended durability. Additionally, its industry-common size makes it versatile for various applications within hydraulic systems requiring precise pressure control and management.
