Proportional Directional Valve 4WRPDH6C3B12L-2X/M/24SD6U - Bosch Rexroth R901379366

On winding and tensioning axes the demand keeps changing during operation, so the valve has to convert small command changes cleanly. With 12 l/min nominal flow, 22 l/min as the maximum and internal spool position feedback the control stays stable even at small deflections, at a valve weight of 3.28 kg.

Benefits

• Nominal flow 12 l/min for axes with changing demand
• Maximum flow 22 l/min as the design limit
• Variant 24SD6U with on-board electronics and 24 VDC supply
• Spool symbol C3, four ports, four switching positions
• Operating pressure 350 bar, NBR seals, hydraulic fluid HL

Application

Typical cases are winders, web tensioners and draw controls in converting lines. Tracking axes on machine tools also manage with this nominal flow. Connection is made through a 7-pole connector (6 + PE) to EN 175201-804.
