Fine positioning work calls for a small nominal flow, otherwise the motion turns coarse. The 4WRZ10E1-25-7X/6EG24K4/D3M works at 25 l/min nominal flow in size 10 and withstands an operating pressure of up to 315 bar.

Applications
Valves like this serve axes that must travel slowly and accurately, for instance while feeding a grinding spindle. The small nominal flow spreads the electronic control range across a narrow band of speed. Rapid traverse is usually left to a second axis or to a larger version.
