Proportional Directional Valve 4WRLE16E250LJ-4X/MXY/24F1 - Bosch Rexroth R901504517

If pilot control is to be influenced neither by working pressure nor by return pressure, full separation is the way there. The 4WRLE16E250LJ-4X/MXY/24F1 is fed through X, relieved through Y and turns a 4...20 mA command into 250 l/min nominal flow.

Benefits

• External pilot oil supply and external return, so the pilot stage works with a constant control pressure.
• 250 l/min nominal flow in size 16 at operating pressures up to 350 bar.
• 4...20 mA current command, resistant to interference over longer cable runs across a plant.
• Spool symbol E, linear characteristic curve, 3 switching positions and 4 ports.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.84 kg, CE conformity.

Applications

Such versions sit on test rigs, on forging presses and on plants with strongly varying system pressure. Constant control pressure keeps step response equal across the cycle. The on-board electronics feed the spool position back and correct deviations on their own.
