The Hydraforce 5621401.M120 (5621401.M120) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. Known as the UP10-31 model, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its normal state, the valve blocks flow from port 2 to port 3. When a predetermined pressure level is reached at port 1, the spool shifts to allow flow from port 2 to port 3. The spring chamber is vented at port 3, meaning that any back pressure at this port will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value, based on the selected ratio, the valve will close and block flow from port 2 to port 3 once again. The UP10-31 features adjustments that cannot be backed out of the valve and prevents springs from going solid, ensuring reliable operation and longevity. It also offers optional spring ranges up to 207 bar (3000 psi), with a hardened spool and cage for extended life. This model is built in an industry-common size for easy integration into existing systems.
