The Hydraforce 5621440.M190 (5621440.M190) 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 steady state, the valve effectively blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber venting at port 3 means that any back pressure directly affects the valve setting on a 1:1 basis. Should the pressure at port 1 fall below the established reload value, the valve closes to block flow from port 2 to port 3 once again. Notably, adjustments on this valve cannot be backed out and are designed to prevent springs from going solid. The UP10-31 features optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for extended durability. Its industry-common size ensures compatibility with various systems.
