Proportional Directional Valve 4WRZ25W6-220-7X/6EG24N9EK4/D3M - Bosch Rexroth R900248412

A tank located far away makes the return path long and back pressure hard to estimate. The 4WRZ25W6-220-7X/6EG24N9EK4/D3M therefore drains its pilot oil through a short dedicated Y line, taps it internally through a pressure reducing valve and controls 220 l/min nominal flow.

Benefits

• Short dedicated Y line to the nearest tank port, independent of the long return path of the working circuit.
• Internal tapping with pressure reducing valve, an X line is not needed.
• 220 l/min nominal flow, flow up to 870 l/min, spool symbol W6 in size 25.
• 20.46 kg weight, 350 bar maximum operating pressure, ISO 4401-08-08-0-05 pattern.
• Concealed auxiliary actuation, supplied at 24 VDC through a 7-pole (6 + PE) plug.

Applications

This is found on extensive plants whose power unit stands in a room of its own. The working return covers long distances there, while pilot oil drains over a short path without pressure. Supply and control stay untouched by it.
