Proportional Directional Valve 4WRPDH6C3B15P-2X/M/24ND6T - Bosch Rexroth R901434519

Fine feed motion on a small axis calls for a valve that resolves tiny command changes cleanly. The direct actuated 4WRPDH6C3B15P-2X/M/24ND6T at size 6 meters 15 l/min nominal flow for that purpose and passes 30 l/min at peak.

Benefits

• 15 l/min nominal flow - flow limited to 30 l/min at size 6, weight 3.26 kg.
• Spool symbol C3 with 4 switching positions - linear fine control range across 4 ports, internal spool position feedback.
• Direct actuation - no pilot oil and no extra channel in the subplate are needed.
• Command value ±10 VDC or 4 to 20 mA - on-board electronics, 24 VDC supply, 12-pole connector (11 + PE).
• Maximum operating pressure 350 bar - connection diagram ISO 4401-03-02-0-05, NBR seals for HL hydraulic fluid.

Applications

The valve rides on travelling blocks at gantries, on swivel axes and on small test cylinders running flat ramps. With flow limited to 30 l/min, a wrongly set command value has limited consequences. Conformity is documented as UKCA for electromagnetic compatibility (EMC) SI2016/1091.
