Proportional Directional Valve 4WRLE16V1-250P-4X/MPY/24A1 - Bosch Rexroth R901499107

A spool with a fine control range separates slow starting from fast travel. The 4WRLE16V1-250P-4X uses spool symbol V1 for that and beyond it meters 250 l/min nominal flow at up to 350 bar.

Benefits

• Spool symbol V1 with a linear fine control range around centre position.
• Nominal flow of 250 l/min, maximum flow 800 l/min.
• Internal pilot supply with an external drain through the Y port.
• Internal position feedback for repeatable spool position.
• Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
• Mass of 13.88 kg, NBR seals, maximum operating pressure 350 bar, CE conformity.

Application

The valve suits positioning axes with a creep speed, tool infeeds and test cylinders building force slowly. The external pilot drain protects the pilot stage from back pressure in the tank line. The connection diagram is ISO 4401-07-07-0-05.
