Proportional Directional Valve 4WRKE10W8-100L-3X/6EG24K31/A1D3M - Bosch Rexroth R901023119

A draw cushion works against the press, so its valve must keep controlling while main pressure falls. The 4WRKE10W8-100L-3X/6EG24K31/A1D3M has its own pilot circuit for that and 100 l/min nominal flow.

Benefits

• Pilot oil supplied and drained externally, the pilot stage stays fed when the main channel loses pressure.
• 100 l/min nominal flow, up to 170 l/min in size 10.
• ±10 V command straight into the on-board electronics, no amplifier card.
• 315 bar maximum operating pressure, spool symbol W8, ISO 4401-05-05-0-05 pattern.
• 8.39 kg, NBR seals and a 7-pole (6 + PE) plug connection.

Applications

The valve controls draw cushions, counter holders and ejector cylinders on forming presses. The external pilot circuit is usually fed from the press pilot supply. When exchanging, ports X and Y must be connected at the subplate.
