The Hydraforce 5621441.M206 (5621441.M206) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed for accumulator-type hydraulic systems. This model, known as the UP10-31, 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. When a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber's venting at port 3 means that any back pressure at this port directly affects the valve setting in a 1:1 ratio. Should the pressure at port 1 fall below the established reload value ratio, the valve will close and block flow from port 2 to port 3 again. Notably, adjustments on this valve cannot be backed out and are designed to prevent springs from reaching a solid state. It offers optional spring ranges up to 207 bar (3000 psi) and is built with a hardened spool and cage for enhanced durability. Additionally, it features an industry-common size for compatibility with various systems.
