Proportional Directional Valve 4WRZE10W6-85-7X/6EG24EK31/A1D3M - Bosch Rexroth R901046893

On the die cushion of a forming press it matters how precisely flow is split between the two cylinder sides. The 4WRZE10W6-85-7X/6EG24EK31/A1D3M uses spool symbol W6 for this, carries 85 l/min nominal flow and takes its pilot oil from the main circuit while the pilot oil return is routed outside.

Benefits

• Spool symbol W6 with three switching positions, plus 85 l/min nominal flow in size 10.
• Internal pilot oil supply, external pilot oil return, pressure reducing valve in the pilot circuit.
• Operating pressure up to 315 bar, maximum flow 170 l/min.
• On-board electronics on 24 VDC, analog ±10 V command value, no extra controller card needed.
• Weight 8.46 kg, NBR seals, HL hydraulic fluid.

Applications

Forming presses, stretch drawing lines and sheet metal centres use this frame for axes of medium power. The subplate mounting to ISO 4401-05-05-0-05 sits on the usual size 10 manifold. Since pilot oil is tapped internally, connecting the four working lines and one pilot return line is enough.
