Proportional Directional Valve 4WRZ25E325-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900979510

A main circuit at 350 bar sits above what pilot control tolerates. The 4WRZ25E325-7X/6EG24N9ETK4/D3M solves that with a built-in pressure reducing valve, draws its pilot oil internally and controls 325 l/min nominal flow.

Benefits

• Pressure reducing valve in the pilot stage, the valve limits its own control pressure and works at high system pressure too.
• Internal supply and internal return, neither an X nor a Y line has to be routed.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol E in size 25.
• 20.48 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

The valve is intended for presses and forging plants that run permanently close to maximum operating pressure. Because pilot control limits its own pressure, a separate pilot supply is dropped. Supply and return run through the channels of the connection pattern.
