Proportional Directional Valve 4WRDE25W6-350L-6X/MXY/24A5 - Bosch Rexroth R901579894

Moving large cylinders quickly and still under control takes flow capacity plus spool position feedback. The 4WRDE25W6-350L-6X/MXY/24A5 supplies 350 l/min rated flow, passes 870 l/min at peak and holds the main spool on the ±10 V command through internal position feedback.

Benefits

• 350 l/min rated flow and up to 870 l/min maximum flow in size 25
• Internal main spool position feedback for repeatable positioning
• On-board electronics, ±10 V command value, 24 VDC supply
• Operating pressure up to 350 bar, port pattern ISO 4401-08-08-0-05
• External pilot oil supply and external pilot oil return, independent of main pressure
• NBR seals, spool symbol W6, weight 25.24 kg

Applications

Valves of this class sit on press cylinders, roll adjustment drives and large test axes where several hundred litres per minute must be metered. External pilot supply keeps the pilot stage fed even when main pressure drops during the cycle. At 25.24 kg the valve needs a correspondingly solid subplate.
