The Hydraforce 5621400.13 (5621400.13) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. Known as the UP10-31 model, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-31 blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting on a 1:1 basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes to block flow again from port 2 to port 3. Key features include non-backable adjustments and spring designs that prevent solidification, enhancing operational reliability and longevity. Additionally, it offers optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for extended service life. Its industry-common size makes it versatile for various applications where precise control of hydraulic fluid flow is required.
