The Hydraforce 5621400.15 (5621400.15) is a screw-in, cartridge-style remote sequence pilot unloading valve specifically designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, it blocks flow from port 2 to port 3 until a predetermined pressure at port 1 is reached, at which point the spool shifts to allow flow between these ports. The spring chamber being vented at port 3 means that any back pressure will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve will close, thus blocking flow again from port 2 to port 3. The UP10-31 is designed with adjustments that cannot be backed out and features springs that do not go solid, ensuring reliable operation. It offers optional spring ranges up to 207 bar (3000 psi) and includes a hardened spool and cage for enhanced durability. Additionally, this model is compatible with industry-common sizes, making it versatile for various applications within hydraulic systems where precise control of fluid flow and pressure is crucial.
