The Hydraforce 5621301.22 (5621301.22) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known for its precision and durability, this model offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the UP10-40X blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, which then shifts the spool to permit flow between these ports. The spring chamber is vented to port 4, ensuring proper operation. If the pressure at port 1 falls below the established reload value, the valve closes to block flow again. Notably, adjustments on this valve cannot be backed out, preventing springs from going solid and ensuring long-term reliability. It features a hardened precision spool and cage for enhanced longevity and fits an industry-common size, making it versatile for various applications in hydraulic systems where precise control of fluid flow is crucial.
