The Hydraforce 5621403.M175 (5621403.M175) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator type hydraulic systems. This model features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the UP10-31 valve blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to allow flow between these ports. The spring chamber is vented at port 3, meaning back pressure here will directly affect the valve setting in a 1:1 ratio. If the pressure at port 1 falls below the established reload value, the valve closes again, blocking flow from port 2 to port 3. Notably, adjustments on this valve cannot be backed out and are designed to prevent springs from going solid. It offers optional spring ranges up to 207 bar (3000 psi), and its hardened spool and cage ensure long-lasting durability. The UP10-31 also fits industry-common sizes, making it versatile for various applications within hydraulic systems where precise control of fluid flow is necessary.
