Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9TK31/F1M - Bosch Rexroth R901067674

A separate pilot oil circuit feeds this valve independently of what the main pump is currently delivering. The 4WRZE25W8-325-7X/6EG24N9TK31/F1M takes pilot oil in externally through port X, drains it internally to tank and releases 325 l/min nominal flow.

Benefits

• Pilot oil supply comes in externally through port X, independent of the main pump.
• Pilot oil return runs internally, with no extra external return line.
• 325 l/min nominal flow, up to 870 l/min possible through the valve.
• Operating pressure up to 350 bar, command signal 4 to 20 mA, 24 VDC supply.
• Spool symbol W8, three switching positions, weight 20.22 kg.

Applications

Layouts like this suit plants with their own pilot oil circuit, for example rolling mills, test rigs and large presses, where pilot pressure is supplied independently of the main pump. Keep the X line within the pilot pressure range given in the datasheet.
