Proportional Directional Valve 4WRLE16W8-200LJ-4X/MPY/24A1 - Bosch Rexroth R901507716

When several consumers discharge into a shared return manifold, back pressure builds up there. This version therefore routes pilot oil through its own Y line straight to tank while taking it internally from the P channel, so no external pilot pump is required. The valve meters 200 l/min nominal and controls the main spool through internal position feedback.

Benefits

• External pilot drain keeps the pilot stage clear of back pressure in the shared return line.
• Internal pilot supply from the P channel, no dedicated pilot pump needed.
• 200 l/min nominal flow, limit 800 l/min, operating pressure 350 bar.
• Internal position feedback with linear characteristic and spool symbol W8.
• Command value plus/minus 10 V, 24 VDC supply, on-board electronics.
• Valve weight 11.64 kg, port pattern ISO 4401-07-07-0-05.

Applications

This combination is the usual choice in multi-axis systems where several valves discharge into one return line. The Y line should run directly to tank without a check valve and without a filter. If system pressure falls below the minimum pilot pressure, the main spool returns to its rest position.
