Proportional Directional Valve 4WRKE27E500L-3X/6EG24K31/F1D3V - Bosch Rexroth R901414322

Where long signal runs cause trouble, a current command value is the more robust choice. The 4WRKE27E500L-3X accepts 4...20 mA, controls 500 l/min nominal flow and corrects spool position through internal feedback instead of merely commanding it.

Benefits

• Internal spool position feedback delivers high accuracy of the flow setpoint
• 500 l/min nominal flow and up to 1000 l/min peak flow in size 27
• The 4...20 mA current command value stays immune to interference over long cables
• Linear characteristic curve gives predictable behaviour inside the higher-level control loop
• FKM seals for applications with raised temperature or special fluid requirements
• Subplate mounting ISO 4401-08-08-0-05, operating pressure up to 270 bar

Technical data

Applications

Intended for position-controlled large cylinders in presses, testing machines and rolling mill drives. External pilot oil supply and external pilot oil return keep the pilot stage stable even when system pressure fluctuates. The current command value suits control cabinets mounted far from the valve.
