The Hydraforce 5621401.13 (5621401.13) is a versatile screw-in, cartridge-style remote sequence pilot unloading valve designed for use in accumulator-type hydraulic systems. Known as the UP10-31, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%, making it adaptable to various system requirements. 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 is vented at port 3, meaning that any back pressure at this port directly affects the valve setting with a ratio of 1:1. If the pressure at port 1 falls below the established reload value ratio, the valve will close again, stopping flow from port 2 to port 3. One of the key features of this product is its robust design; adjustments cannot be backed out of the valve and are engineered to prevent springs from becoming solid under pressure. Additionally, it offers optional spring ranges up to 207 bar (3000 psi), which enhances its flexibility and adaptability in various applications. The hardened spool and cage ensure long-lasting performance even under demanding conditions. With its industry-common size, it integrates seamlessly into existing systems without requiring significant modifications or adaptations.
