Proportional Directional Valve 4WRTE10W8-100L-4X/6EG24TK31/F1M - Bosch Rexroth R901561635

A control loop is easier to tune when gain stays constant over the entire stroke. The 4WRTE10W8-100L-4X/6EG24TK31/F1M carries a continuously linear characteristic curve for that and provides 100 l/min nominal flow with spool symbol W8.

Key benefits

• Continuously linear characteristic curve, control gain stays the same across the signal range.
• Spool symbol W8 at 100 l/min nominal flow, maximum flow 170 l/min.
• A 4...20 mA setpoint into the on-board electronics, 24 VDC supply.
• External pilot oil supply with internal return, only one additional line required.
• 3 switching positions, 4 ports, connection pattern ISO 4401-05-05-0-05, operating pressure up to 350 bar.
• 8.7 kg weight, NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

The valve suits closed control loops on test rigs and positioning axes where a controller is tuned for constant plant gain. The current setpoint stays unambiguous even on long cables. At 100 l/min nominal flow it covers medium cylinders.
