Proportional Directional Valve 4WRLE16W6-200LJ-4X/MXY/24F1 - Bosch Rexroth R901474413

On plants whose system pressure swings widely, the pilot stage should not notice it. The 4WRLE16W6-200LJ-4X/MXY/24F1 receives control oil through X, drains through Y and turns a 4...20 mA command into 200 l/min nominal flow at up to 350 bar.

Benefits

• External pilot oil supply through X and external return through Y for a constant control pressure over the cycle.
• 4...20 mA current command, insensitive to voltage drop on long cables.
• 200 l/min nominal flow in size 16 against a series maximum of 800 l/min.
• Spool symbol W6, 3 switching positions, on-board electronics with position feedback.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.84 kg, CE conformity.

Applications

Valves like this sit on test rigs, on rolling mill adjustment and on presses with accumulator operation where system pressure falls over the cycle. Separate pilot routing keeps the step response even. Sealing is NBR for mineral oil of class HL.
