Proportional Directional Valve 4WRZE16W6-125-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901399662

A large power unit often drives small axes too, and then nominal flow becomes the sizing figure. The 4WRZE16W6-125-7X/6EG24N9ETK31/F1D3M handles 125 l/min here, holds pilot pressure constant with a built-in pressure reducing valve and needs no control lines of its own.

Benefits

• 125 l/min nominal flow in size 16, with the series maximum flow at 460 l/min.
• Integrated pressure reducing valve, keeping control pressure within range even at 350 bar system pressure.
• Internal pilot oil supply and internal return, mounted solely through ISO 4401-07-07-0-05.
• 4...20 mA current command at the on-board electronics, 24 VDC supply.
• Spool symbol W6, concealed auxiliary actuation, NBR seals, weight 12.2 kg, UKCA conformity.

Applications

Its place is on auxiliary axes of large presses, on clamping cylinders and on tool adjustment. At 125 l/min the resolution stays fine on small piston areas although the power unit could supply much more. Spool symbol W6 blocks in mid position.
