Proportional Directional Valve 4WRZE25E3-220-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901036568

The spool symbol determines what happens at the actuator ports in the centre position. The 4WRZE25E3-220-7X/6EG24N9ETK31/A1D3M uses symbol E3 and controls 220 l/min nominal flow in size 25 at operating pressure up to 350 bar.

Benefits

• Symbol E3 in three switching positions, differing from the widely used W9 versions of the range.
• 220 l/min nominal flow, 870 l/min maximum, operating pressure up to 350 bar.
• Internal pilot oil supply and internal return without additional control lines.
• Pressure reducing valve in the pilot circuit plus concealed auxiliary actuation for service work.
• Command value ±10 V DC, 24 V DC supply, weight 20.58 kg, NBR seals.

Applications

The valve is used on axes whose rest state requires defined behaviour at ports A and B, for example with suspended loads or accumulator circuits. Size 25 and mounting pattern ISO 4401-08-08-0-05 allow replacement of other valves in the same range as long as the symbol matches the circuit. Internal piloting keeps installation effort small.
