Proportional Directional Valve 4WRLE16E1-250LJ-4X/MXY/24A1 - Bosch Rexroth R901404333

The larger the controlled flow, the more a fluctuating pilot pressure affects stroke time. This 4WRLE16E1-250LJ therefore separates both circuits, with pilot oil entering at X and returning through Y. It meters 250 l/min nominal, allows up to 800 l/min at peak and is driven by a plus/minus 10 V voltage.

Benefits

• 250 l/min nominal flow and an 800 l/min limit from a size 16 body.
• Fully separated pilot circuit through X and Y for consistent stroke times.
• Internal main spool position feedback, linear characteristic, spool symbol E1.
• Command value plus/minus 10 V, on-board electronics mounted on the valve.
• Operating pressure 350 bar with NBR seals for HL fluid.
• Valve weight 11.94 kg, 3 switching positions, 4 ports.

Applications

Typical installations have long cylinders and high travel speeds, for example press ejectors and lifting tables. Because the pilot stage does not depend on working pressure, response time stays constant across the cycle. The Y return must run to tank without any restriction.
