The Hydraforce 5621401.27 (5621401.27) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-31, 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 until a predetermined pressure is reached at port 1, prompting the spool to shift and allow flow between these ports. The valve's spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting on a 1:1 basis. Should the pressure at port 1 fall below the established reload value ratio, the valve will close and block flow again from port 2 to port 3. The UP10-31 features adjustments that cannot be backed out of the valve and prevents springs from going solid, ensuring reliable operation over time. It also includes optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for enhanced durability. Additionally, it comes in an industry-common size for ease of integration into existing systems.
