Pre-fill valve F 25-12 (V) HAWE

Possible Applications

This pre-fill valve is engineered for high-capacity hydraulic circuits, particularly within large industrial hydraulic presses used for metal forming, deep drawing, and powder compaction. In these systems, the valve manages rapid fluid transfer between the main cylinder and the fluid reservoir during the fast approach and return strokes, significantly reducing pump energy requirements. The integrated hydraulic pre-relief mechanism is crucial for eliminating high-pressure decompression shocks, ensuring smooth operation, and preventing hydraulic hammering when shifting from high-speed travel to pressing force. Consequently, it finds primary application in heavy machinery where precise de-pressurization of large oil volumes is necessary to protect structural components and extend the service life of the entire hydraulic circuit.
