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.
