Proportional Directional Valve 4WRLE27V600L-4X/MXY/24F1 - Bosch Rexroth R901520723

A separate pilot circuit keeps a large valve working even when main pressure sags. The 4WRLE27V600L-4X/MXY/24F1 relies on exactly that, with external pilot supply through X, external return through Y and a 4 to 20 mA command for 600 l/min rated flow.

Benefits

• External pilot oil supply and external pilot oil return for a standalone pilot circuit
• 600 l/min rated flow, up to 1850 l/min maximum flow in size 27
• 4 to 20 mA current command through on-board electronics, 24 VDC supply
• Spool symbol V, three switching positions, internal spool position feedback
• Operating pressure up to 270 bar, port pattern ISO 4401-08-08-0-05
• CE conformity, NBR seals, 20.74 kg

Applications

Typical for press lines and test plants with a dedicated pilot pump where working pressure swings heavily inside the cycle. With supply and return separated, the pilot stage runs regardless of the main circuit. Carry the MXY code over on a replacement, otherwise the manifold will not match.
