The Hydraforce 5621463.15 (5621463.15) 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 offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the UP10-31 prevents flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber is vented at port 3, meaning any back pressure will directly affect the valve setting with a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve closes and blocks flow once again from port 2 to port 3. This product features non-backout adjustments and prevents springs from becoming solid, ensuring durability and reliability in operation. The UP10-31 also offers optional spring ranges up to 207 bar (3000 psi) and is constructed with a hardened spool and cage for extended lifespan, fitting industry-common sizes for versatile application across various hydraulic systems.
