Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901090623

Converting an existing NG32 axis to spool symbol W8 should leave the electrical side untouched. This pilot-operated 4/3 proportional directional valve stays with the familiar ±10 V command value, meters 600 l/min of nominal flow and withstands an operating pressure of 350 bar.

Benefits

• Spool symbol W8 combined with a ±10 V command value keeps the existing wiring in place
• Nominal flow of 600 l/min, peaks to 1600 l/min at an operating pressure of 350 bar
• Internal pilot oil supply with external pilot oil return removes one pilot line from the manifold
• Linear characteristic curve plus internal spool position feedback give repeatable positioning moves
• Connection diagram ISO 4401-10-09-0-05, 3 switching positions, 4 ports, 36.74 kg

Application

Intended as a replacement in existing press, injection moulding and test bench axes of size 32. Because connection diagram as well as voltage command value stay the same, the conversion covers only the valve plus its pilot oil return. On-board electronics on 24 VDC take over spool control as soon as the connector is plugged in.
