Proportional Directional Valve 4WRTE10E1-50L-4X/6EG24K31/A1M - Bosch Rexroth R901029040

A dedicated pilot oil unit supplies constant pilot pressure whatever the main circuit is doing. The 4WRTE10E1-50L-4X/6EG24K31/A1M is designed for this arrangement and meters a 50 l/min nominal flow on a plus/minus 10 V command.

Advantages

• External pilot oil supply and external return, matching a dedicated pilot power unit.
• Plus/minus 10 V command on the on-board electronics, no signal conversion needed.
• Nominal flow of 50 l/min, up to 170 l/min total, operating pressure up to 350 bar.
• Spool symbol E1 with three switching positions on four ports.
• Connection diagram ISO 4401-05-05-0-05, size 10 subplate mounting.
• Weight of 8.41 kg, NBR seals, HL hydraulic fluid.

Applications

The valve is used on machine tools and test rigs with a separate pilot circuit. Because supply and return run outside, the pilot stage keeps its operating point even when the main circuit cycles hard. Ports X and Y have to be provided on the manifold.
