The Hydraforce 5621401.M175 (5621401.M175) 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 steady state, the UP10-31 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to allow 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 on a 1:1 ratio. If the pressure at port 1 drops below the established reload value, the valve will close and block flow from port 2 to port 3 again. This product features non-backout adjustments that prevent springs from becoming solid and offers optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage ensure long-lasting durability, and it comes in an industry-common size for easy integration into existing systems.
