The Hydraforce 5621461V (5621461V) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in 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 default state, the valve effectively blocks flow from port 2 to port 3 until a predetermined pressure at port 1 is reached, at which point the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning any back pressure there will directly affect the valve's setting at a one-to-one ratio. If the pressure at port 1 falls below the established reload value, determined by the chosen ratio, the valve closes again to block flow from port 2 to port 3. The design includes features such as adjustments that cannot be backed out of the valve and prevent springs from becoming solid. It also offers optional spring ranges up to 207 bar (3000 psi), with a hardened spool and cage for extended durability. This model adheres to industry-common sizing standards, making it compatible with various hydraulic systems requiring precise control over fluid flow based on pressure conditions.
