Proportional Directional Valve 4WRLE16W6-200LJ-4X/MPY/24A1 - Bosch Rexroth R901531641

Back pressure in the return falsifies pilot control. The 4WRLE16W6-200LJ-4X/MPY/24A1 therefore drains pilot oil to the outside through its own Y port, draws it internally from the P port and controls 200 l/min nominal flow at up to 350 bar.

Benefits

• External pilot oil return through Y, so no back pressure from the T port acts on the pilot stage.
• Internal pilot oil supply from the P port, which removes one feed line.
• 200 l/min nominal flow in size 16, operating pressure up to 350 bar.
• Plus or minus 10 V command at the on-board electronics with spool position feedback.
• Spool symbol W6, mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.76 kg.

Applications

The typical place is a power unit with return filter, cooler or a long path to tank, for example on presses and injection moulding machines. At 200 l/min nominal flow, medium cylinders can be moved with a calm start. The Y port is routed to tank without pressure.
