The Hydraforce 5621302.M69 (5621302.M69) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed for use in accumulator-type hydraulic systems. This model, known as the UP10-40X, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve effectively blocks flow from port 2 to port 3 until a predetermined pressure at port 1 is reached. Once this pressure threshold is met, the spool shifts to permit flow from port 2 to port 3 while venting the spring chamber to port 4. The valve automatically closes and blocks flow again if the pressure at port 1 drops below the established reload value. Notable features include adjustments that cannot be backed out of the valve, preventing springs from going solid, and a hardened precision spool and cage that ensure long life. Additionally, this valve conforms to industry-common sizes for ease of integration into existing systems.
