Proportional Directional Valve 4WRLE10V100P-4X/MXT/24F1 - Bosch Rexroth R901475914

A position controller is easier to tune when the valve curve keeps the same slope over the whole stroke. Spool symbol V delivers exactly that, and this size 10 valve puts it to work with 100 l/min nominal flow and a 4...20 mA current command value.

Benefits

• The linear V characteristic keeps loop gain constant across the full signal range.
• 100 l/min nominal flow at 350 bar, peak flow up to 300 l/min.
• 4...20 mA command value for plants with a remote controller and electrically noisy surroundings.
• External pilot oil supply with internal return needs only the additional X line.
• On-board electronics, CE conformity, weight 9.1 kg.

Applications

This version is used in closed position and force loops where the controller expects a known curve rather than having to linearise one itself. Examples are testing machines, infeed axes and calender gaps. The return through T assumes a tank line with low back pressure.
