Proportional Directional Valve 4WRDE16V1-220P-6X/MXY/24A1 - Bosch Rexroth R901507911

In a materials testing bay the pilot circuit usually runs on its own, so that control stays free of load peaks. The 4WRDE16V1-220P-6X/MXY/24A1 is laid out for this, taking pilot oil from outside and returning it outside, at 220 l/min nominal flow and 350 bar.

Benefits

• External pilot oil supply and external return, marked MXY in the type code.
• The fine control range of spool V1 allows small force steps during test sequences.
• Nominal flow 220 l/min, maximum 460 l/min, operating pressure up to 350 bar.
• Connection diagram ISO 4401-07-07-0-05 in size 16 with 4 ports and 3 switching positions.
• Command value ±10 V, on-board electronics, NBR seals, weight 10.5 kg.

Applications

The valve serves testing machines, fatigue rigs and control axes with high repeatability demands. A dedicated pilot circuit keeps the pilot stage free of feedback from working pressure. A size 16 subplate is enough for mounting.
