The Hydraforce 5621440.M69 (5621440.M69) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for 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 default state, it prevents flow from port 2 to port 3. When a specified pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber venting at port 3 means that any back pressure will directly influence the valve setting on a one-to-one basis. If the pressure at port 1 decreases below the preset reload value, the valve automatically closes to block flow from port 2 to port 3 again. The UP10-31 includes adjustments that cannot be backed out of the valve and prohibits springs from going solid, ensuring reliable operation. It also offers optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for enhanced longevity. The design adheres to industry-common sizing standards, making it a versatile component in hydraulic applications requiring dependable pressure control and sequence operations.
