The Hydraforce 5621401.17.5 (5621401.17.5) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve blocks flow from port 2 to port 3 until a predetermined pressure at port 1 is reached, prompting the spool to shift and allow flow between these ports. The spring chamber\u2019s venting at port 3 ensures that back pressure directly affects the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve closes to block flow once again. The design features adjustments that cannot be backed out of the valve and safeguards against springs going solid, ensuring reliable operation over time. With optional spring ranges extending up to 207 bar (3000 psi), and components like hardened spools and cages for enhanced durability, this product fits industry-common sizes for versatile application in hydraulic systems demanding precise pressure management and control.
