Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9EK31/F1M - Bosch Rexroth R900746202

When cycle time is the bottleneck, a larger nominal flow is often the simplest remedy, because the mounting pattern stays the same. With 325 l/min instead of 220 l/min this 4WRZE25 speeds up the rapid stroke on the same ISO 4401-08-08-0-05 interface.

Benefits

• 325 l/min nominal flow on an unchanged size 25 mounting pattern.
• Up to 870 l/min maximum flow at 350 bar operating pressure.
• 4...20 mA current command, insensitive to voltage drop in the cable.
• Internal pilot supply with external return, only one extra line on the manifold.
• On-board electronics with a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The change pays off on presses, injection moulding machines and test benches whose cylinder fills too slowly in rapid traverse. Before the swap it is worth checking that pump and line cross sections can deliver the higher flow. The valve weighs 20.2 kg and runs on HL hydraulic fluid.
