Pre-fill valve F 63-30 (V) HAWE

Possible Applications

This high-capacity pilot-operated pre-fill valve is engineered primarily for large vertical hydraulic presses, such as metal forging presses, deep-drawing machinery, and rubber or composite molding presses. In these systems, the valve facilitates rapid gravity-induced cylinder filling and evacuation during the idle approach and return strokes, significantly reducing pump energy requirements. During the high-pressure working phase, the pilot operation ensures leak-free seating and smooth decompression before the main press stroke opens, preventing hydraulic shock and extending the service life of the circuit components.
