High-Flow Pre-Fill Valve Type F 200-100 HAWE Hydraulik

Possible Applications

This high-capacity pre-fill valve is engineered primarily for large hydraulic presses, deep drawing machinery, and heavy metal-forming equipment where rapid cylinder filling and evacuation are critical during the approach and return strokes. In such systems, the valve serves as a large-diameter conduit between the fluid reservoir and the main press ram, allowing massive volumes of oil to be drawn in by gravity or suction during the fast-down phase. Upon contact with the workpiece, it rapidly closes to enable high-pressure clamping and pressing operations. Because it requires a strict vertical installation orientation, it is ideally integrated directly onto the top crown or main cylinder manifold of heavy forging and extrusion presses, streamlining hydraulic architecture and minimizing parasitic pressure drops in high-tonnage production environments.
