The Hydraforce 5621341.M75 (5621341.M75) 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%. It operates by blocking flow from port 2 to port 3 in its steady state. When a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber of the valve is vented to port 4, and if the pressure at port 1 falls below the established reload value, the valve closes again to block flow from port 2 to port 3. Notable features include adjustments that cannot be backed out of the valve, preventing springs from going solid and ensuring reliability. Additionally, it incorporates a hardened precision spool and cage for enhanced durability and long life, while maintaining an industry-common size for easy integration into existing systems.
