The Hydraforce 5621404.M150 (5621404.M150) is a screw-in, cartridge-style remote sequence pilot unloading valve specifically designed for accumulator-type hydraulic systems. Known as the UP10-31 model, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. It operates by blocking flow from port 2 to port 3 in its steady state. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow from port 2 to port 3. 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 established reload value, the valve closes and blocks flow from port 2 to port 3 again. Notable features include adjustments that cannot be backed out of the valve, preventing springs from going solid, and optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage components ensure long-lasting durability. Additionally, this model is designed with an industry-common size for ease of integration into existing systems.
