Proportional Directional Valve 4WRZ10E1-25-7X/6EG24K4/D3M - Bosch Rexroth R901158929

The smaller the nominal flow, the finer an axis can be guided by the command signal. The 4WRZ10E1-25-7X/6EG24K4/D3M is rated at 25 l/min and carries spool symbol E1 in size 10.

Benefits

• 25 l/min nominal flow for sensitive travel, flow range up to 170 l/min
• Spool symbol E1, 3 switching positions, 4 ports
• 315 bar maximum operating pressure, ISO 4401-05-05-0-05 interface
• External pilot oil supply and external return for steady pilot pressure
• 24 VDC through external electronics, 7-pole (6 + PE) connector to EN 175201-804
• 8.24 kg with integrated pressure reducing valve and NBR seals

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.
