The Hydraforce 5621461.25 (5621461.25) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. It features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the UP10-31 model blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, at which point the spool shifts to permit flow between these ports. The valve's design ensures that back pressure at port 3 directly affects the valve setting due to the spring chamber being vented there. If the pressure at port 1 falls below the pre-set reload value, the valve will close again, blocking flow from port 2 to port 3. This model is equipped with adjustments that cannot be backed out of the valve and prevent springs from becoming solid, ensuring reliability and durability. It offers optional spring ranges up to 207 bar (3000 psi) and features a hardened spool and cage for extended lifespan. The UP10-31's industry-common size makes it versatile for various applications requiring precise control over hydraulic fluid flow based on system pressure changes.
