Proportional Directional Valve 4WRKE16W8-220L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901450818

Long signal runs across a shop floor cope better with a current loop than with a voltage. This variant takes 4...20 mA and turns it into up to 220 l/min nominal flow through its pilot-operated main spool carrying symbol W8.

Advantages

• 4...20 mA command, immune to drop over long cable routes
• 220 l/min nominal flow, 460 l/min peak
• Internal pilot oil supply and internal pilot oil return
• Spool symbol W8 with a blocked centre position
• 350 bar maximum operating pressure, 11.04 kg

Applications

Sprawling plants where the valve sits far from its controller are the natural application. Rolling mill hydraulics and long press lines are typical. HL fluid runs against NBR seals.

Manufacturer
