The Hydraforce 5621433.M138 (5621433.M138) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically 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 standard operation, the UP10-31 blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow from port 2 to port 3. The spring chamber's venting at port 3 means that any back pressure directly affects the valve setting in a one-to-one ratio. Should the pressure at port 1 fall below the established reload value according to its ratio, the valve will close again, stopping flow from port 2 to port 3. This model features adjustments that cannot be backed out of the valve and prohibits springs from becoming solid. It also provides optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage ensure long-lasting durability and performance, and its industry-common size allows for versatile application in various hydraulic setups.
