Proportional Directional Valve 4WRZE25W6-220-7X/6EG24EK31/A1D3M - Bosch Rexroth R901052964

Sizing has to decide between resolution and throughput. The 4WRZE25W6-220-7X provides a nominal flow of 220 l/min in size 25, passes 870 l/min at peak and works up to 350 bar operating pressure.

Benefits

• Nominal flow of 220 l/min, connection diagram ISO 4401-08-08-0-05.
• Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
• Pressure reducing valve in the pilot stage keeps pilot pressure independent of system pressure.
• Internal pilot supply with an external drain through the Y port.
• Spool symbol W6 with three switching positions and four ports.
• Mass of 20.95 kg, NBR seals, maximum flow 870 l/min.

Application

The build is used on feed and clamping axes in machine building and on test rigs with a moderate oil demand. The UKCA marking covers operation in Great Britain. A dedicated Y port to tank has to be provided for the pilot drain.
