The Hydraforce 5621440.M70 (5621440.M70) is a screw-in, cartridge-style remote sequence pilot unloading valve designed specifically for accumulator-type hydraulic systems. This model, known as the UP10-31, features optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its standard operational state, it effectively blocks flow from port 2 to port 3. When a predetermined pressure is reached at port 1, the spool shifts to enable flow between port 2 and port 3. The spring chamber's venting at port 3 means that any back pressure here directly affects the valve setting on a one-to-one basis. If the pressure at port 1 decreases below the established reload value ratio, the valve automatically closes to block flow from port 2 to port 3 once again. The UP10-31 valve ensures reliability with adjustments that cannot be backed out of the valve and prohibits springs from going solid. It also offers optional spring ranges up to 207 bar (3000 psi) and incorporates a hardened spool and cage for enhanced longevity. Additionally, it maintains an industry-common size for ease of integration into existing systems.
