The Hydraforce 5621820.18.75 (5621820.18.75) is a screw-in, cartridge-style, internally piloted pilot unloading valve designed for accumulator-type hydraulic systems. Known by its model code UPCV10-F41, this valve features an internal check valve and a fixed reload pressure ratio of 80%. In its default state, the valve blocks flow from port 3 to port 4 while permitting flow from port 1 to port 2. Upon reaching a predetermined pressure at ports 2 and 3, the spool shifts to facilitate free flow from port 3 to port 4, effectively unloading the pilot at port 3. If the pressure at port 2 falls below the established reload value ratio, the valve closes to block flow from port 3 to port 4 again. The spring chamber is vented through port 4 for efficient operation. This product is characterized by hardened precision spool and cage components for enhanced durability and offers various seal options for customization according to specific requirements.
