The Hydraforce 5621440.M150 (5621440.M150) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its normal state, it blocks flow from port 2 to port 3. When a predetermined pressure at port 1 is reached, the spool shifts to permit flow between these ports. The valve's design features a spring chamber vented at port 3, meaning any back pressure here will directly affect the valve setting on a one-to-one basis. Should the pressure at port 1 decrease below the pre-established reload value ratio, the valve closes to block flow again from port 2 to port 3. Notably, adjustments on this valve cannot be reversed out of the unit and are designed to prevent springs from becoming solid. The UP10-31 can handle optional spring ranges up to 207 bar (3000 psi) and is constructed with hardened spools and cages for extended durability. It also adheres to industry-common sizing standards for ease of integration into existing systems.
