Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R900977488

In a compact power unit every centimetre next to the valve counts, because fittings and control lines take more room than the valve itself. This version needs neither an X nor a Y line and delivers 220 l/min with spool symbol W6.

Benefits

• Pilot stage fed and drained internally, so the space needed is limited to the mounting face.
• Pressure reducing valve in the pilot line means no external reducing stage even at 350 bar system pressure.
• Flow rating 220 l/min with spool symbol W6, maximum flow 870 l/min.
• Voltage command of plus/minus 10 V, on-board electronics, 24 VDC supply.
• Mass 20.76 kg, interface pattern ISO 4401-08-08-0-05, hydraulic fluid HL.

Technical data

Applications

It is meant for compact power units and machines with tight cabinet and manifold space, such as clamping systems and mobile test equipment. Because the electronics sit on the valve, the card slot disappears as well. The mounting face has to be flat and clean.
