When an axis needs more oil, the answer is a higher nominal flow, not higher pressure. The 4WRZ16W8-180-7X/6EG24N9ETK4/D3V delivers 180 l/min nominal flow in size 16, takes up to 460 l/min and works up to 350 bar.

Applications
The valve is used on presses, injection moulding machines and test rigs with controlled main axes. Higher nominal flow shortens travel time on long cylinder strokes while the control structure stays the same. The external electronics sit in the cabinet and remain accessible for diagnosis and replacement.
