The Hydraforce 5621301.M138 (5621301.M138) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. Known as the UP10-40X, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it blocks flow from port 2 to port 3, but once a predetermined pressure is reached at port 1, the spool shifts to allow flow between these ports. The spring chamber vents to port 4, and if the pressure at port 1 falls below the established reload value ratio, the valve closes to block flow again. This valve features adjustments that cannot be backed out and prohibits springs from going solid, ensuring reliable operation. It also includes a hardened precision spool and cage for enhanced durability and long life. The UP10-40X's industry-common size makes it a versatile component suitable for various hydraulic applications requiring efficient pressure management and control.
