Proportional Directional Valve 4WRPDH6C5B40P-2X/M/24ND6U - Bosch Rexroth R901405782

Web tension plus winding force change quickly, so the valve has to follow the command without delay. The 4WRPDH6C5B40P-2X/M/24ND6U releases 40 l/min rated flow for that, correcting spool position continuously through internal feedback.

Benefits

• 40 l/min rated flow with 50 l/min maximum for rapid command changes.
• Spool symbol C5 with 4 switching positions across 4 ports, linear fine control range.
• Internal spool position feedback corrects deviations before they show up at the axis.
• Directly actuated, independent of a pilot circuit, operating pressure up to 350 bar.
• Command value plus minus 10 V DC or 4 to 20 mA, 24 V DC, 12-pole connector (11 + PE), 3.58 kg.

Applications

The rating makes sense on winders, web tension controllers, follow-up axes whose command value keeps changing. Size 6 keeps the valve block compact although 50 l/min are on hand. For steady holding duties a smaller spool stage of the same series is enough.
