The Hydraforce 5621400.07.5 (5621400.07.5) is a screw-in, cartridge-style remote sequence pilot unloading valve, specifically designed for accumulator-type hydraulic systems. This model, known as the UP10-31, offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its steady state, the valve effectively 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's venting at port 3 means that any back pressure will directly affect the valve setting in a 1:1 ratio. Should the pressure at port 1 fall below the established reload value for the chosen ratio, the valve will close to block flow once more. Notably, this design ensures that adjustments cannot be backed out of the valve and prevents springs from becoming solid during operation. It also features optional spring ranges up to 207 bar (3000 psi) and utilizes a hardened spool and cage for enhanced longevity. Additionally, it complies with industry-common sizing standards, making it versatile for various applications within hydraulic systems seeking reliable performance and durability in controlling fluid flow based on pressure changes.
