The Hydraforce 5621301.18.75 (5621301.18.75) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. Known as the UP10-40X, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, at which point the spool shifts to permit flow between these ports. The spring chamber vents to port 4, and if the pressure at port 1 decreases below the established reload value ratio, the valve will close to block flow once again from port 2 to port 3. Key features of this product include adjustments that cannot be backed out of the valve and mechanisms that prevent springs from going solid, ensuring reliable operation and longevity. The hardened precision spool and cage contribute to extended service life while maintaining industry-common sizing for easy integration into existing systems.
