The Hydraforce 5621441.M150 (5621441.M150) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in 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 from port 2 to port 3. When a specific pressure is reached at port 1, the spool shifts to permit flow between these ports. Due to the spring chamber being vented at port 3, any back pressure here 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 will close, stopping flow from port 2 to port 3. The design includes features such as adjustments that cannot be backed out of the valve and springs that are prevented from going solid. It also offers optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for enhanced durability. With its industry-common size, this component promises compatibility and long-lasting performance in demanding hydraulic applications.
