Proportional Directional Valve 4WRLE16E180SJ-4X/MXY/24A1 - Bosch Rexroth R901401779

Where an approach is slow and the following travel is brisk, an unevenly graded characteristic helps. The 4WRLE16E180SJ-4X/MXY/24A1 therefore works progressively, controls 180 l/min nominal flow at up to 350 bar and takes its pilot oil through X.

Benefits

• Progressive characteristic curve, fine resolution in the small signal range and large flow at the end of the stroke.
• 180 l/min nominal flow in size 16 against a series maximum flow of 800 l/min.
• External pilot oil supply and external return, independent of the pressure in the working circuit.
• Plus or minus 10 V command at the on-board electronics, spool symbol E, 3 switching positions.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.59 kg, CE conformity.

Applications

Such valves sit on joining axes, on bending machines and on test cylinders where a gentle touch precedes a fast return stroke. The progressive curve shifts resolution to where the process is slow. 180 l/min nominal flow covers the rapid stroke that follows.
