The Hydraforce 5621441.M190 (5621441.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%. In its default state, the valve blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts, allowing flow between these ports. The spring chamber's venting at port 3 means that any back pressure here will directly affect the valve setting on a 1:1 basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes again, blocking flow from port 2 to port 3. Key features include non-backable adjustments that prevent springs from compressing solidly and optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage ensure long-lasting performance, and its industry-common size facilitates easy integration into existing systems.
