Proportional Directional Valve 4WRKE10W8-50L-3X/6EG24K31/A1D3M - Bosch Rexroth R901347386

As cylinder bore grows the nominal flow has to grow with it without losing control quality. The 4WRKE10W8-50L-3X/6EG24K31/A1D3M provides 50 l/min nominal flow for that job and is commanded by ±10 V.

Benefits

• 50 l/min nominal flow, up to 170 l/min in size 10.
• ±10 V command into the on-board electronics, no separate amplifier card required.
• Pilot oil supplied and drained externally, pilot pressure and relief can be chosen freely.
• 315 bar maximum operating pressure, three switching positions, ISO 4401-05-05-0-05 pattern.
• Spool symbol W8, 8.4 kg, NBR seals for HL hydraulic fluid.

Applications

The valve drives press cylinders, draw cushions and infeed axes in the medium power range. A separate pilot circuit keeps the pilot stage supplied even while main pressure is lowered. Valves of the same pilot variant with a different nominal flow fit the same subplate.
