Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9EK31/A1M - Bosch Rexroth R901033632

An ordinary analogue output card with ±10 V is enough to run this axis, no converter is needed in between. The valve turns the voltage command into 325 l/min nominal flow at 350 bar, drawing pilot oil internally and returning it externally.

Benefits

• ±10 V command matches the analogue outputs of common controllers and axis cards.
• 325 l/min nominal flow, up to 870 l/min maximum, at 350 bar operating pressure.
• Internal pilot supply with external return means only one extra line on the manifold.
• On-board electronics replace the amplifier and shorten the signal path to a few centimetres.
• Connection through a 7-pole connector (6 + PE) to EN 175201-804, 24 VDC supply.

Applications

The valve is used on axes driven by a PLC or a motion controller with a voltage command, for example in presses, bending machines and test benches. The sign of the command sets the direction of travel. The valve weighs 20.12 kg.
