The Hydraforce 5621441.M207 (5621441.M207) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for 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, it blocks flow from port 2 to port 3. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The valve's spring chamber is vented at port 3, meaning any back pressure there will directly affect the valve setting on a one-to-one basis. Should the pressure at port 1 fall below the established reload value ratio, the valve will close again, blocking flow from port 2 to port 3. Notably, adjustments on this valve cannot be backed out, ensuring that springs do not become solid during operation. It also offers optional spring ranges up to 207 bar (3000 psi). Constructed with a hardened spool and cage, this model ensures durability and long life while maintaining an industry-common size for easy integration into existing systems.
