The Hydraforce 5621401.M150 (Material Number: 5621401.M150) is a screw-in, cartridge-style remote sequence pilot unloading valve designed 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. When a predetermined pressure is reached at port 1, the spool shifts, allowing flow from port 2 to port 3. The spring chamber vented at port 3 ensures that any back pressure directly affects the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value, the valve closes again to block flow. The design ensures that adjustments cannot be backed out of the valve, and safeguards are in place to prevent springs from going solid. It also features optional spring ranges up to 207 bar (3000 psi) and incorporates a hardened spool and cage for extended durability. This model is compatible with industry-common sizes, making it versatile for various applications requiring reliable hydraulic control solutions.
