The Hydraforce 5621301.17.5 (5621301.17.5) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed 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, it effectively 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 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. This product's design ensures that adjustments cannot be backed out of the valve and prevents springs from going solid, enhancing reliability and longevity. The hardened precision spool and cage further contribute to its durability, making it suitable for long-term use in various hydraulic applications. Additionally, its industry-common size allows for seamless integration into existing systems without requiring significant modifications.
