The Hydraforce 5621401.M190 (5621401.M190) 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 offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%, allowing for precise control of hydraulic system operations. In its default state, the UP10-31 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to enable flow between these ports. The valve's design includes a vented spring chamber at port 3, meaning any back pressure here will directly affect the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value ratio, the valve automatically closes to block flow again from port 2 to port 3. Key features of this model include adjustments that cannot be backed out of the valve and designs that prevent springs from going solid. It also supports optional spring ranges up to 207 bar (3000 psi). The components are crafted with hardened spools and cages for extended durability, and it fits industry-common sizes, making it versatile for various applications requiring reliable hydraulic control.
