Pre-fill valve F 160-76 HAWE

Possible Applications

This pilot-operated pre-fill valve is engineered for heavy hydraulic presses, particularly large metal-forming machinery such as deep drawing presses, scrap metal balers, and massive injection molding units where rapid cylinder filling and evacuation are critical during non-working strokes. It functions primarily between the fluid reservoir and the main press cylinder, allowing massive volumes of hydraulic oil to be drawn in or expelled by gravity and suction rather than being pumped actively. This specific operating principle drastically reduces energy consumption and pump sizing requirements during the fast approach phase, while maintaining reliable high-pressure sealing during the actual working press stroke.
