Proportional Directional Valve 4WRKE16W8-150L-3X/6EG24K31/F1D3M - Bosch Rexroth R901431602

Some installations keep a separate filtered circuit for pilot duty. This variant is laid out for exactly that, since pilot oil supply and pilot oil return are both external. The main spool carrying symbol W8 passes 150 l/min nominal flow.

Advantages

• External pilot oil supply and external pilot oil return
• 150 l/min nominal flow at 350 bar maximum operating pressure
• 4...20 mA command into the on-board electronics
• Spool symbol W8, three switching positions, ISO 4401-07-07-0-05 interface
• 12.28 kg, NBR seals for HL fluid

Applications

The layout targets plants whose main circuit fluctuates heavily or runs close to contamination limits. A separate pilot circuit then keeps the pilot stage clean and steady. Test equipment and special presses are common fields.
