The Hydraforce 5621440.M180 (5621440.M180) is a screw-in, cartridge-style remote sequence pilot unloading valve 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 prevents flow between port 2 and port 3. When a preset pressure is reached 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 affect the valve setting at a ratio of 1:1. If the pressure at port 1 falls below the predetermined reload value, the valve closes to block flow again from port 2 to port 3. Key features include adjustments that cannot be backed out of the valve and mechanisms that prevent springs from becoming solid. The valve offers optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for enhanced durability. It also comes in an industry-common size for ease of integration into existing systems.
