The Hydraforce 5621400.M70 (Material Number: 5621400.M70) is a screw-in, cartridge-style, remote sequence, pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-31 model, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning that any back pressure directly affects the valve setting with a ratio of 1:1. If the pressure at port 1 falls below the set reload value ratio, the valve closes again to block flow from port 2 to port 3. Notable features include adjustments that cannot be backed out of the valve and springs that are designed to avoid becoming solid. It also offers optional spring ranges up to 207 bar (3000 psi) and includes hardened spool and cage components for extended durability. Its industry-common size makes it versatile for various applications requiring reliable hydraulic control and management within accumulator systems.
