The Hydraforce 5621401.M75 (5621401.M75) is a versatile UP10-31 screw-in, cartridge-style valve designed for remote sequence and pilot unloading in accumulator-type hydraulic systems. This valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%, allowing for precise control in various applications. In its default state, the UP10-31 blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to permit flow between these ports. The spring chamber's venting at port 3 ensures that any back pressure directly affects the valve setting at a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve automatically closes to block flow from port 2 to port 3 again. This model includes several important features that enhance its functionality and durability. Notably, adjustments on this valve cannot be backed out, preventing accidental disassembly or misconfiguration. The design also ensures that adjustments do not allow springs to become solid, which could otherwise lead to operational failures or reduced lifespan. With optional spring ranges up to 207 bar (3000 psi), it accommodates a wide range of hydraulic system requirements. Additionally, the hardened spool and cage components contribute to extended service life under demanding conditions. Its industry-common size facilitates easy integration into existing systems without requiring extensive modifications or custom fittings.
