Proportional Directional Valve 4WRZE25W8-220-7X/6EG24K31/A1M - Bosch Rexroth R900747368

If the working pressure varies widely, internal piloting makes the pilot pressure vary with it. The 4WRZE25W8-220-7X/6EG24K31/A1M avoids that coupling through external pilot oil supply and external return, controlling 220 l/min nominal flow with spool symbol W8.

Benefits

• External pilot oil supply and external pilot oil return, pilot pressure stays constant
• 220 l/min nominal flow, maximum flow 870 l/min
• Spool symbol W8 with three switching positions and four ports
• Analogue command value ±10 V, on-board electronics, supply voltage 24 VDC
• Operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05, 20.18 kg

Application

A sensible choice on axes with strongly changing load, for example presses with a drawing and holding step or test benches with load reversal. The separate piloting also allows several valves to share one supply. The operating medium is hydraulic fluid HL.
