Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/A1M - Bosch Rexroth R901028487

The 4WRZE10W6-85-7X/6EG24N9EK31/A1M is the voltage variant of the 85 l/min step with a W6 spool. Pilot oil is taken internally from the main circuit, the drain runs externally to tank, and operating pressure reaches 315 bar.

Advantages

• Analog ±10 V command value at the on-board electronics, 24 V DC supply
• Nominal flow 85 l/min, maximum flow 170 l/min
• Internal pilot oil supply with external pilot oil return
• Operating pressure to 315 bar, W6 spool, 3 switching positions
• Concealed auxiliary actuation, built without a pressure reducing valve
• UKCA under SI2016/1091, weight 7.98 kg, NBR seals for HL oil

Applications

The plate is installed in forming and lifting plants whose controller emits a voltage and whose return line carries counter pressure. At 85 l/min it moves larger cylinders quickly. Concealed auxiliary actuation permits moves without a control signal.
