The Hydraforce 5621401.M80 (5621401.M80) is a screw-in, cartridge-style remote sequence pilot unloading valve specifically designed for accumulator-type hydraulic systems. Known as the UP10-31, this valve offers optional fixed unload/reload pressure ratios of 60%, 70%, or 80%. In its default state, it effectively blocks flow from port 2 to port 3. Upon reaching a predetermined pressure at port 1, the spool shifts to permit flow between these ports. The spring chamber's venting at port 3 means any back pressure here will directly impact the valve setting on a one-to-one basis. If the pressure at port 1 falls below the established reload value ratio, the valve closes, stopping flow from port 2 to port 3. Notable features include adjustments that cannot be backed out of the valve and those that prohibit springs from going solid. Additionally, it offers optional spring ranges up to 207 bar (3000 psi). The hardened spool and cage enhance durability and ensure long-lasting performance. This model is also recognized for its industry-common size, making it a versatile component in various applications within hydraulic systems where reliable control of fluid flow is crucial.
