The Hydraforce 5621331 (5621331) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. This model offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-40X valve blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to allow flow between these ports. The spring chamber is vented to port 4, ensuring smooth operation. If the pressure at port 1 decreases below the established reload value based on the chosen ratio, the valve automatically closes, blocking flow once again from port 2 to port 3. The design features adjustments that cannot be backed out of the valve and prohibit springs from going solid, enhancing durability and reliability. Additionally, it incorporates a hardened precision spool and cage for extended lifespan and maintains an industry-common size for compatibility with various hydraulic systems.
