The Hydraforce 5621433.22.5 (5621433.22.5) is a screw-in, cartridge-style remote sequence pilot unloading valve designed for accumulator-type hydraulic systems. This model, also known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, 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 allow flow through these ports. The spring chamber's venting at port 3 means that any back pressure 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 to block flow again. The UP10-31 features adjustments that cannot be backed out of the valve and are designed to prevent springs from going solid, ensuring reliability and long service life. It also includes optional spring ranges up to 207 bar (3000 psi) and is constructed with hardened spools and cages for durability. This model fits industry-common sizes, making it versatile for various applications requiring precise control within hydraulic systems.
