Proportional Directional Valve 4WRDE16V1-220L-6X/MXY/24A1 - Bosch Rexroth R901577896

Under fast load changes the spool position feedback decides how cleanly the axis follows its command value. This pilot-operated size 16 build converts 220 l/min nominal flow and works up to a maximum operating pressure of 350 bar.

Benefits

• 220 l/min nominal flow with a maximum flow of 460 l/min.
• Maximum operating pressure 350 bar at a valve weight of 14.04 kg.
• Spool symbol V1 with 3 switching positions and 4 ports, mounting pattern ISO 4401-07-07-0-05.
• External pilot oil supply and external pilot oil return keep the pilot oil independent of the working pressure.
• On-board electronics with an analog command value of ±10 V on 24 VDC, NBR seals for hydraulic fluid HL.

Applications

Typical applications are materials testing machines, presses and forging lines with position-controlled axes. A nominal flow of 220 l/min moves large cylinders, while the maximum flow of 460 l/min leaves headroom for rapid strokes. The external pilot circuit lets the pilot oil be filtered separately and held at constant pressure. Mounting uses the ISO 4401-07-07-0-05 pattern.
