Proportional Directional Valve 4WRZE10W6-50-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954649

The clamping unit of a plastics machine needs an axis that meters 50 l/min cleanly without extra pipework. The 4WRZE10W6-50-7X/6EG24ETK31/A1D3M places pilot oil supply and pilot oil return inside the valve, uses spool symbol W6 and holds up to 315 bar operating pressure.

Benefits

• Nominal flow 50 l/min in size 10, maximum flow 170 l/min.
• Internal pilot oil supply and internal return, no extra pilot drillings in the manifold.
• Spool symbol W6 with three switching positions, connection diagram ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot circuit, operating pressure up to 315 bar.
• Analog ±10 V command value on on-board electronics, 24 VDC, weight 8.54 kg.

Applications

Clamping units, ejector axes and core pulls on injection moulding machines sit in this flow range. The size 10 subplate pattern keeps the valve interchangeable with other frames of the same series. The output stage lives in the valve, the machine controller only supplies the voltage command.
