The Hydraforce 5621401.M130 (5621401.M130) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in 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 steady state, the valve effectively blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the internal spool shifts to permit flow from port 2 to port 3. The spring chamber's venting at port 3 means that 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 will close again, preventing flow between ports 2 and 3. Notably, adjustments on this valve cannot be backed out, ensuring that springs do not go solid during operation. It features optional spring ranges up to 207 bar (3000 psi), and its hardened spool and cage design contribute to a long operational life. Additionally, it comes in an industry-common size for ease of integration into existing systems.
