The Hydraforce 5621401.19 (5621401.19) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, prompting the spool to shift and allow flow between these ports. The spring chamber venting at port 3 means that back pressure directly affects the valve setting at a 1:1 ratio. If the pressure at port 1 falls below the established reload value ratio, the valve will close to block flow from port 2 to port 3 once again. Key features include adjustments that cannot be backed out of the valve and adjustments that prevent springs from going solid. The UP10-31 can handle optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for extended durability. Its industry-common size makes it versatile for various applications within hydraulic systems requiring precise control over flow sequences and pressure management.
