Proportional Directional Valve 4WRLE16E250LJ-4X/MPY/24A1 - Bosch Rexroth R901514566

Control loops with a voltage command are common in machine tools. The 4WRLE16E250LJ-4X/MPY/24A1 fits into them, accepts plus or minus 10 V, feeds the pilot stage internally and relieves it to the outside through Y, at 250 l/min nominal flow.

Benefits

• Plus or minus 10 V command, directly compatible with common axis controllers and analogue cards.
• 250 l/min nominal flow at operating pressures up to 350 bar in size 16.
• Internal pilot oil supply, external return through Y keeps the pilot stage clear of back pressure.
• Spool symbol E, 3 switching positions, on-board electronics with position feedback.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.6 kg.

Applications

The valve is used on infeed axes of presses, on mould clamping units and on hydraulic feeds. Nominal flow of 250 l/min gives enough headroom for rapid strokes at medium piston areas. Through the ISO 4401-07-07-0-05 subplate pattern, exchange against an equally built valve is straightforward.
