The Hydraforce 5621404.13 (5621404.13) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This valve, known as the UP10-31, features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it blocks flow from port 2 to port 3 until a predetermined pressure is achieved at port 1, upon which the spool shifts to permit flow between these ports. The design ensures that back pressure at port 3 directly affects the valve setting in a 1:1 ratio due to the vented spring chamber at this port. Should the pressure at port 1 fall below the established reload value based on the ratio, the valve will close and block flow again from port 2 to port 3. Notable features include adjustment mechanisms that cannot be backed out of the valve and prevent springs from going solid, as well as optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage enhance durability and longevity, while its industry-common size facilitates versatile application across various hydraulic systems.
