Proportional Directional Valve 4WRTE10W6-50P-4X/6EG24K31/A1M - Bosch Rexroth R901301166

The choice of spool symbol decides how a small axis behaves in mid position. The 4WRTE10W6-50P-4X/6EG24K31/A1M uses symbol W6 at 50 l/min nominal flow and works with a pilot circuit routed entirely externally.

Key benefits

• Spool symbol W6 with 3 switching positions and 4 ports, connection pattern ISO 4401-05-05-0-05.
• 50 l/min nominal flow in size 10, maximum flow 170 l/min.
• External pilot oil supply and external return, pilot pressure independent of working pressure.
• Plus minus 10 V command, 24 VDC supply, on-board electronics without an amplifier card.
• Linear characteristic curve with fine control range, internal spool position feedback, up to 350 bar.
• 8.46 kg weight, NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

The valve works on test rigs and machine tools whose power unit runs a pilot circuit of its own. At 50 l/min nominal flow it controls small cylinders and rotary actuators. An external pilot circuit keeps control behaviour identical under changing load pressure.
