The Hydraforce 5621403 (5621403) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed 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. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber's venting at port 3 enables back pressure to directly affect the valve setting on a 1:1 basis. Should the pressure at port 1 decrease below the established reload value ratio, the valve automatically closes to block flow from port 2 to port 3 again. Notable features include adjustments that cannot be backed out of the valve and prohibit springs from going solid. The product also offers optional spring ranges up to 207 bar (3000 psi) and includes hardened spool and cage components for enhanced longevity. Its industry-common size ensures compatibility with a wide range of applications within hydraulic systems requiring precise control over fluid flow and pressure management.
