The Hydraforce 5621434.28 (Material Number: 5621434.28) is a UP10-31 screw-in, cartridge-style, remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. This valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, it blocks flow from port 2 to port 3. When a predetermined pressure at port 1 is reached, the spool shifts to allow flow from port 2 to port 3. The spring chamber is vented at port 3, meaning that any back pressure here directly affects the valve setting at a ratio of 1:1. Should the pressure at port 1 fall below the established reload value, the valve closes to block flow between ports 2 and 3 again. Notable features include adjustments that cannot be backed out of the valve and adjustments that prevent springs from going solid. The UP10-31 supports optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for enhanced durability. Its industry-common size makes it versatile for various applications in hydraulic systems where reliable sequence control is necessary.
