The Hydraforce 5621431 (Material Number: 5621431) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the valve blocks flow from port 2 to port 3. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning any back pressure here will directly affect the valve setting on a one-to-one basis. Should the pressure at port 1 fall below the specified reload value ratio, the valve will close again, blocking flow from port 2 to port 3. Key features include adjustments that cannot be backed out of the valve and designs that prevent springs from going solid. It also offers optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage ensure long-lasting performance, and its industry-common size allows for easy integration into existing systems.
