Proportional Directional Valve 4WRPDH6C4B40P-2X/M/24SD6S - Bosch Rexroth R901487395

On short strokes the acceleration phase decides the cycle time. The 4WRPDH6C4B40P-2X/M/24SD6S supplies 40 l/min rated flow for that, keeps the spool on track through internal feedback, manages without a pilot circuit.

Benefits

• 40 l/min rated flow with up to 50 l/min maximum for short acceleration distances.
• Spool symbol C4 across 4 switching positions with 4 ports, linear characteristic with fine control range.
• Directly actuated spool valve, no pilot oil, hence one line fewer inside the block.
• Command input for plus minus 10 V DC or 4 to 20 mA, 24 V DC through the 12-pole connector (11 + PE).
• Operating pressure up to 350 bar, ISO 4401-03-02-0-05, NBR seals, HL fluid, 3.58 kg.

Applications

The combination goes into cycling axes in assembly lines, follow-up cylinders, test rigs with changing motion profiles. Position feedback makes the axis reach its target repeatably despite the speed. For slow precision motion the 15 l/min spool stage remains the finer alternative.
