Proportional Directional Valve 4WRPDH6C4B40L-2X/V/24ED6T - Bosch Rexroth R901436807

Direct actuated valves respond without a pilot stage and need no pilot oil. The 4WRPDH6C4B40L-2X works that way in size 6, meters 40 l/min nominal flow and holds spool position through internal feedback.

Benefits

• Direct actuated, neither pilot oil nor a minimum pilot pressure is needed.
• Nominal flow of 40 l/min, maximum flow 50 l/min.
• Internal spool position feedback with a linear characteristic, spool symbol C4.
• Command value selectable as ±10 VDC or 4...20 mA, supplied at 24 VDC.
• Four switching positions across four ports, connection diagram ISO 4401-03-02-0-05.
• FKM seals, mass 3.54 kg, maximum operating pressure 350 bar.

Application

The valve sits on small controlled axes, clamping cylinders and test set-ups that demand fast command changes. Without a pilot stage there is no dependence on pilot pressure, so work continues at low system pressure. Wiring uses a 12-pole (11 + PE) connector.
