Proportional Directional Valve 4WRPDH10C4B100L-2X/M/24TD6T - Bosch Rexroth R901395440

A steady characteristic curve is what lets an axis accelerate without a jolt. The 4WRPDH10C4B100L-2X/M/24TD6T follows the analog command value through internal spool position feedback, carries 100 l/min nominal flow and works up to 315 bar.

Benefits

• Internal spool position feedback for steady following behaviour on ramps and slow travel.
• Nominal flow 100 l/min at operating pressures up to 315 bar.
• Spool symbol C4, four switching positions, mounting pattern ISO 4401-05-04-0-05.
• Direct actuated, so no dead time from an upstream pilot stage.
• Command value ±10 VDC or 4 ... 20 mA at the on-board electronics, 24 VDC supply.
• 12-pole connector (11 + PE), mass 7.46 kg.

Applications

The valve is used on materials testing machines, endurance rigs and presses with a prescribed force profile. Ramps can be resolved finely because the valve follows the command without stepping. Closed-loop force or position control still needs a higher level controller.
