The Hydraforce 5621821.M155 (5621821.M155) is a screw-in, cartridge-style, internally piloted unloading valve designed for accumulator-type hydraulic systems. Known as the UPCV10-F41, this valve features an internal check valve and offers a fixed reload pressure ratio of 80%. In its default state, it blocks flow from port 3 to port 4 while allowing flow from port 1 to port 2. When a predetermined pressure is reached at ports 2 and 3, the spool shifts to permit free flow from port 3 to port 4, effectively unloading the pilot at port 3. Should the pressure at port 2 fall below the established reload value ratio, the valve closes again, preventing flow from port 3 to port 4. The spring chamber of this valve is vented to port 4. Designed with durability in mind, it includes hardened precision spool and cage components for extended life span. Additionally, users can select from various seal options and optional fixed reload pressure ratios to suit specific application needs.
