Proportional Directional Valve 4WRPEH6C1B24L-3X/M/24C6-967 - Bosch Rexroth R901556777

Without feedback the spool of a proportional valve drifts out of position under load. The 4WRPEH6C1B24L-3X/M/24C6-967 measures spool position inside the valve and corrects it, at 24 l/min nominal flow in size 6 and up to 350 bar operating pressure.

Benefits

• Internal spool position feedback, the measured position is controlled against the command value.
• Command value ±10 mA, processed by the on-board electronics without an external amplifier.
• 24 l/min nominal flow at 350 bar maximum operating pressure in size 6.
• Directly actuated, no pilot oil and no pilot stage, ISO 4401-03-02-0-05 pattern.
• Spool symbol C1, four switching positions, four ports, 3.1 kg weight, NBR seals, CE conformity.

Applications

The valve is used on positioning axes, test rigs and machine tools that have to reach short travels accurately. The signed current command sets direction and opening in a single signal. Supply runs at 24 VDC through the electrical connection on the valve.
