Proportional Directional Valve 4WRPDH6C1B24L-2X/M/24ND6T - Bosch Rexroth R901468199

Swivel and indexing modules in assembly cells slam when the oil flow is switched on hard. The 4WRPDH6C1B24L-2X/M/24ND6T instead opens in proportion to the command signal, up to 24 l/min at 350 bar, and keeps the spool steady through its internal position transducer.

Benefits

• Spool symbol C1, four switching positions for drives that need a defined rest position.
• Stepless build-up of flow to 24 l/min, operating pressure of 350 bar at most.
• Internal position feedback, so load changes do not shift the opening that was set.
• Size 6 with subplate mounting to ISO 4401-03-02-0-05, four ports, 3.33 kg.
• 24 VDC supply, command value 10 VDC bipolar or 4 ... 20 mA, NBR seals for HL fluid.

Application

The valve is used on swivel drives, indexing tables and handling axes where acceleration and braking set the cycle time. Ramping the command signal shapes the motion profile without mechanical dampers. Four switching positions also cover the de-energised rest position.
