Proportional Directional Valve 4WRKE32W6-400L-3X/6EG24K31/A1D3M - Bosch Rexroth R901044433

Large axes with high throughput need a pilot circuit that stays independent of working pressure. The 4WRKE32W6-400L-3X/6EG24K31/A1D3M in size 32 delivers 400 l/min nominal flow, reaches 1550 l/min at peak and holds operating pressure up to 350 bar with external pilot oil supply and return.

Advantages

• 400 l/min nominal flow, 1550 l/min at peak, in size 32.
• External pilot oil supply and return keep the pilot circuit separate from working pressure.
• Spool symbol W6 with a linear curve gives even speed control.
• A ±10 V command value with on-board electronics simplifies the link to the controller.
• 37.4 kg weight at up to 350 bar maximum operating pressure with NBR seals for HL hydraulic fluid.

Applications

The valve controls large feed and positioning axes on presses, rolling mills and test rigs that require the pilot circuit kept separate from main pressure. External pilot oil supply needs its own feed and return port. Connection diagram and mounting pattern follow ISO 4401-10-09-0-05.
