The Hydraforce 5621341.18.75 (5621341.18.75) is a screw-in, cartridge-style remote sequence pilot unloading valve, designed specifically for accumulator-type hydraulic systems. Known as the UP10-40X, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-40X blocks flow from port 2 to port 3 until a predetermined pressure is attained at port 1, causing the spool to shift and allow flow between these ports. The spring chamber is vented to port 4, and if the pressure at port 1 falls below the established reload value, the valve closes to block flow again. Notably, adjustments on this valve cannot be backed out, preventing springs from going solid and ensuring longevity with a hardened precision spool and cage design. This model also fits industry-common sizes, making it versatile for various applications where reliable control of hydraulic systems is essential.
