The Hydraforce 5621340.21 (5621340.21) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-40X, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its standard operation, the UP10-40X blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, at which point the spool shifts to allow flow between these ports. The spring chamber vents to port 4 during this process. If the pressure at port 1 decreases below the established reload value, the valve closes and blocks 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 springs that are prevented from going solid, ensuring reliable performance. Additionally, it boasts a hardened precision spool and cage for extended durability and fits an industry-common size for versatile application across various hydraulic systems.
