The Hydraforce 5621371.13.9 (Material Number: 5621371.13.9) is a UP10-40X screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the UP10-40X blocks flow between port 2 and port 3. When a predetermined pressure is reached at port 1, the spool shifts to permit flow from port 2 to port 3, while the spring chamber vents to port 4. Should the pressure at port 1 fall below the established reload value, the valve will close, once again blocking flow from port 2 to port 3. The design ensures that adjustments cannot be backed out of the valve and prevents springs from becoming solid, enhancing reliability and durability. The valve also features a hardened precision spool and cage for extended life and is compatible with industry-standard sizes, making it a versatile component in hydraulic systems requiring precise control of fluid flow based on pressure conditions.
