The Hydraforce 5621401.M140 (5621401.M140) 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 features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-31 effectively blocks flow from port 2 to port 3. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow between port 2 and port 3. The spring chamber's venting at port 3 means that any back pressure at this point directly affects the valve setting in a 1:1 ratio. 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. It has optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for extended durability. The UP10-31 is also noted for its industry-common size, making it compatible with various hydraulic applications where reliable pressure control is essential.
