Proportional Directional Valve 4WRZ25W8-325-7X/6EG24N9K4/M - Bosch Rexroth R900713034

When the return line is pressurised at times and working pressure falls far, neither channel is fit for pilot control. The 4WRZ25W8-325-7X/6EG24N9K4/M solves that with external supply and external return and controls 325 l/min nominal flow.

Benefits

• External supply through X, pilot pressure is kept even at low working pressure.
• External return through Y, pressure in the working return does not reach pilot control.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol W8 in size 25.
• 20.2 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

Regenerative circuits occur on presses and cylinder drives where return oil is fed back to the piston side. The pilot circuit stays completely separate and is supplied on its own. The axis itself is controlled through external electronics.
