The Hydraforce 5621821.M186 (5621821.M186) is a screw-in, cartridge-style, internally piloted unloading valve designed for use in 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 normal state, it blocks flow from port 3 to port 4 while allowing flow from port 1 to port 2. Upon reaching a predetermined pressure at ports 2 and 3, the spool shifts to enable 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, the valve closes again to block flow from port 3 to port 4. The spring chamber of this valve is vented to port 4. Key features include an internal check valve for enhanced performance, optional fixed reload pressure ratios for versatile applications, and a hardened precision spool and cage that ensure long-lasting durability. Additionally, users can choose from various seal options to suit specific needs. This product is ideal for maintaining efficient hydraulic system operations by controlling pressure and flow with precision and reliability.
