The Hydraforce 5621442.18 (5621442.18) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve 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 and opens upon reaching a predetermined pressure at port 1, allowing flow between these ports. The valve setting is directly affected by back pressure at port 3 due to its vented spring chamber. If the pressure at port 1 drops below the established reload value, the valve closes, blocking flow again. The UP10-31 is designed with adjustments that cannot be backed out of the valve and prevent springs from going solid, ensuring reliability and longevity. It offers optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for extended life. Additionally, it fits an industry-common size, making it versatile for various applications requiring precise control in hydraulic systems.
