The Hydraforce 5621401.M180 (5621401.M180) 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, features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow from port 2 to port 3. The spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value ratio, the valve will close again, blocking flow from port 2 to port 3. Notably, adjustments on this valve cannot be backed out and are designed to prevent springs from becoming solid. The UP10-31 also offers optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for enhanced durability. Its industry-common size makes it versatile for various applications requiring reliable hydraulic control.
