The Hydraforce 5621400.11 (5621400.11) 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 default state, it blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to enable flow from port 2 to port 3. The spring chamber is vented at port 3, meaning any back pressure here will directly impact the valve setting in a 1:1 ratio. If the pressure at port 1 drops below the established reload value based on the chosen ratio, the valve closes to once again block flow from port 2 to port 3. This product features adjustments that cannot be backed out of the valve and prohibits springs from reaching solid state conditions. It offers optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for extended durability. Additionally, it adheres to an industry-common size for ease of integration into existing systems.
