Proportional Directional Valve 4WRPDH6C3B24L-2X/V/24ND6T - Bosch Rexroth R901566319

Small axes and pilot circuits are not controlled with a size 16 body but with a direct operated valve. The size 6 4WRPDH6C3B24L meters 24 l/min nominal at 350 bar operating pressure and weighs just 3.7 kg. It works with four switching positions and controls its spool through internal position feedback, so the set flow is held even when load pressure changes.

Benefits

• Direct operated, no pilot stage and therefore no minimum pilot pressure.
• 4 switching positions instead of the usual 3, with spool symbol C3 defining the assignment.
• 24 l/min nominal flow at 350 bar, port pattern ISO 4401-03-02-0-05.
• Command value either plus/minus 10 VDC or 4...20 mA, no converter needed.
• Internal spool position feedback keeps the characteristic independent of load.
• Only 3.7 kg valve weight, FKM seals for a wider fluid range.

Applications

The valve controls small cylinders, tool adjustment drives and the pilot stage of larger valves. Because it is direct operated, it still works at low system pressure where a pilot operated size would stall. The 12-pole connector carries the feedback signals alongside command and supply.
