The Hydraforce 5621400.M120 (5621400.M120) is a screw-in, cartridge-style remote sequence pilot unloading valve 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%. It operates by blocking flow from port 2 to port 3 in its steady state. When a predetermined pressure is reached at port 1, the spool shifts to permit flow from port 2 to port 3. The spring chamber venting at port 3 allows back pressure to directly affect the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value, the valve closes and blocks flow again. Notably, adjustments on this valve cannot be backed out, preventing springs from becoming solid and ensuring reliability over time. The UP10-31 features optional spring ranges up to 207 bar (3000 psi) and utilizes a hardened spool and cage for enhanced durability. Its industry-common size makes it versatile for various applications requiring reliable hydraulic control.
