The Hydraforce 5621404 (5621404) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. Known as the UP10-31, this valve features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its standard operation, the valve blocks flow from port 2 to port 3 until a predetermined pressure is reached at port 1, at which point the spool shifts to permit flow between these ports. The spring chamber venting at port 3 means that any back pressure directly affects the valve setting in a one-to-one 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 product ensures that adjustments cannot be backed out of the valve and prevents springs from going solid, offering enhanced reliability and safety. It also comes with optional spring ranges up to 207 bar (3000 psi) and features hardened spool and cage components for extended durability. Additionally, its industry-common size makes it versatile for various applications requiring precise control over hydraulic system pressures.
