Proportional Directional Valve 4WRZ25W6-325-7X/6EG24N9EK4/D3M - Bosch Rexroth R900248411

Existing manifolds often offer only one of the two pilot ports to the outside. The 4WRZ25W6-325-7X/6EG24N9EK4/D3M fits that case because it taps internally, limits pressure itself and drains through Y, at 325 l/min nominal flow.

Benefits

• Internal tapping with its own pressure reducing valve, an X port on the manifold is not required.
• External return through the existing Y port, the tank channel stays unloaded.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol W6 in size 25.
• 20.34 kg weight, 350 bar maximum operating pressure, ISO 4401-08-08-0-05 pattern.
• Concealed auxiliary actuation, commanded at 24 VDC through an external amplifier.

Applications

Such boundary conditions arise when older valves are replaced and the successor expects a different pilot arrangement. The manifold stays as it is and only the existing Y port is reused. Before fitting, check that the main circuit delivers enough pilot oil.
