Proportional Directional Valve 4WRPDH6C3B15P-2X/M/24SD6S - Bosch Rexroth R901329736

An adjustment axis stands still most of the time, moving only a few millimetres. The 4WRPDH6C3B15P-2X/M/24SD6S is built for that, works at 15 l/min rated flow, tracks spool position through internal feedback.

Benefits

• 15 l/min rated flow, 30 l/min maximum, rated for short, infrequent setting movements.
• Internal spool position feedback corrects a drifting opening without the control system having to intervene.
• Spool symbol C3 with 4 switching positions across 4 ports, linear characteristic with fine control range.
• Directly actuated, hence no pilot circuit, operating pressure up to 350 bar, HL fluid.
• Command value plus minus 10 V DC or 4 to 20 mA, 24 V DC, 12-pole connector (11 + PE), 3.57 kg.

Applications

Axes like this appear on extruder tooling, calibration units, roll gap adjustment drives. Low flow matches setting distances in the millimetre range that have to be reached repeatably. Through the 12-pole connector the spool position signal can be tied into plant diagnostics.
