The Hydraforce 5621403.13.8 (5621403.13.8) 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 spool shifts to permit flow from port 2 to port 3. The spring chamber's venting at port 3 means that any back pressure there will directly affect the valve setting in a 1:1 ratio. Should the pressure at port 1 fall below the established reload value ratio, the valve closes and blocks flow from port 2 to port 3 again. Key features of this model include adjustments that cannot be backed out of the valve and prohibitions against springs going solid, which ensures reliability and durability in operation. The UP10-31 also offers optional spring ranges up to 207 bar (3000 psi), with hardened spools and cages that contribute to its long lifespan. Its industry-common size makes it versatile for various applications requiring precise control over hydraulic system pressures in accumulator setups.
