Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901064186

Whether 360 or 520 l/min is the right size follows from the cylinder feed rate, and this version covers the middle of size 32 with 360 l/min nominal flow on a 4 to 20 mA current command.

Key benefits

• 360 l/min nominal flow instead of 520 l/min, which gives finer command resolution over the stroke.
• 4 to 20 mA current command on a 24 VDC supply, insensitive to voltage drop along long cables.
• Internal pilot oil supply, external pilot oil return, suited to counter pressure in the tank line.
• Spool symbol W8 in 3 switching positions across 4 ports to ISO 4401-10-09-0-05.
• 44.25 kg, integrated pressure reducing valve to 350 bar operating pressure, 1600 l/min maximum flow.

Applications

A nominal flow of 360 l/min matches medium press cylinders, hoisting gear and baling presses. Where return filters build pressure in the tank line, the external pilot return protects the function of the pilot valve. HL is the specified hydraulic fluid.
