The Hydraforce 5621400.M69 (5621400.M69) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-31, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-31 blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure here will directly affect the valve setting in a one-to-one ratio. If the pressure at port 1 falls below the pre-established reload value, the valve closes and blocks flow again. Notable features of this model include adjustments that cannot be backed out of the valve and springs that are prevented from going solid. It offers optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for extended durability. Additionally, it comes in an industry-common size, making it versatile for various applications where controlling hydraulic fluid flow is critical.
