The Hydraforce 5621401.25 (5621401.25) is a screw-in, cartridge-style, remote sequence pilot unloading valve designed for use in 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 steady state, the UP10-31 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the internal spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure at this port will directly impact 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 and block flow from port 2 to port 3 once again. The design includes features such as adjustments that cannot be backed out of the valve and adjustments that prevent springs from going solid. It also offers optional spring ranges up to 207 bar (3000 psi) and utilizes a hardened spool and cage for enhanced durability and long service life. Additionally, it has an industry-common size for easy integration into existing systems.
