The Hydraforce 5621400.14.5 (Material Number: 5621400.14.5) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, the UP10-31 blocks flow between port 2 and port 3. Once a predetermined pressure is reached at port 1, the spool shifts to permit flow from port 2 to port 3. The spring chamber's venting at port 3 means that any back pressure at this port will affect the valve setting directly in a one-to-one ratio. If the pressure at port 1 falls below the established reload value, determined by the chosen ratio, the valve closes to block flow once again from port 2 to port 3. This model features adjustments that cannot be backed out of the valve and prohibits springs from reaching a solid state. It offers optional spring ranges up to 207 bar (3000 psi), ensuring versatility in various applications. The hardened spool and cage are designed for durability and long life, making it a reliable component in hydraulic systems requiring precise control of flow based on pressure conditions. Its industry-common size ensures compatibility with standard system configurations, providing an efficient solution for managing hydraulic pressures effectively within specified parameters.
