Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R900760949

Filters, coolers and long lines create back pressure in the tank return that detunes the pilot stage of a valve. This 4WRZE32W8-360-7X therefore routes the pilot oil return separately and keeps switching time reproducible at 360 l/min nominal flow.

Key benefits

• External pilot oil return decouples the control circuit from back pressure in the working return line.
• Internal pilot oil supply means no second pump and one port fewer.
• 360 l/min nominal flow, with a permitted flow of 1600 l/min.
• A pressure reducing valve in the pilot circuit holds control pressure constant at up to 350 bar working pressure.
• A 4 to 20 mA command and 24 VDC supply at the 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve is installed in presses, hoists and test systems whose return line runs through a cooler and filter. With several valves on one shared return line, the separate pilot return prevents mutual interference. Subplate mounting to ISO 4401-10-09-0-05 matches the standard for size 32.
