The Hydraforce 5621401.11.5 (5621401.11.5) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for 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 resting state, the valve blocks flow from port 2 to port 3. Once a predetermined pressure is reached at port 1, the spool shifts, permitting flow from port 2 to port 3. The spring chamber is vented at port 3, which means that any back pressure here will directly affect the valve setting on a 1:1 basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes again to block flow between port 2 and port 3. This design ensures that adjustments cannot be backed out of the valve and prevents springs from becoming solid under high-pressure conditions. The UP10-31 accommodates optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for enhanced durability and long service life. Its industry-common size allows for versatile applications across various hydraulic systems where precise control of fluid flow is necessary.
