Proportional Directional Valve 4WRZE10E1-85-7X/6EG24TK31/A1M - Bosch Rexroth R901380475

Where system pressure collapses during the cycle but the tank return is clean, a single extra pilot line is enough. The 4WRZE10E1-85-7X/6EG24TK31/A1M takes pilot pressure externally and returns the pilot oil internally, at 85 l/min nominal flow.

Benefits

• External pilot oil supply, internal return, only the X line is added.
• 85 l/min nominal flow in size 10, up to 170 l/min maximum.
• Spool symbol E1 with three switching positions and four ports.
• Command value ±10 V through on-board electronics at 24 V DC.
• 315 bar maximum operating pressure at 8.42 kg weight, without a pressure reducing valve in the pilot stage.

Applications

The valve controls medium sized feed and lifting axes in machine tools, presses and test benches. UKCA marking for electromagnetic compatibility to SI2016/1091 eases use in machines for the British market. Subplate mounting follows ISO 4401-05-05-0-05.
