Proportional Directional Valve 4WRZE10E50-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901022076

On the 4WRZE10E50-7X/6EG24N9K31/F1D3M pilot oil supply and draining both run through the X and Y lines, so the pilot stage stays completely separate from the main circuit. The spool of symbol E releases 50 l/min nominal flow, and the 4...20 mA current command value drives it up to 315 bar operating pressure.

Benefits

• External pilot supply and external draining, pilot stage independent of working and return pressure.
• 50 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• Current command value 4...20 mA, on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for emergency movement without control voltage.
• Spool symbol E, 3 switching positions on 4 ports, ISO 4401-05-05-0-05.
• Weight 8.52 kg, NBR seals, UKCA conformity.

Application

The valve is built into plants with a central pilot pressure network in which several axes are fed from the same source. The current input stays readable across long cable runs. The Y line has to run to the tank without back pressure.
