The Hydraforce 5621401.21.5 (5621401.21.5) 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 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to allow flow between these ports. The spring chamber's venting at port 3 means that any back pressure will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve closes to block flow again from port 2 to port 3. This product features adjustments that cannot be backed out of the valve and prohibits springs from becoming solid, ensuring durability and reliability in operation. It also supports optional spring ranges up to 207 bar (3000 psi) and includes hardened spool and cage components for extended life. The UP10-31 is designed with an industry-common size for versatile application across various hydraulic systems requiring precise control of flow based on pressure conditions.
