Proportional Directional Valve 4WRZE25E325-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901503452

Where system pressure and return pressure swing at the same time, the pilot stage of a large directional valve should not notice. The 4WRZE25E325-7X/6EG24N9ETK31/F1M therefore feeds and drains pilot oil externally while metering 325 l/min nominal flow at 350 bar operating pressure.

Benefits

• 325 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• External pilot oil supply and external pilot oil drain keep the pilot stage clear of the working circuit.
• A 4...20 mA current command for long signal runs, and a value below 4 mA reveals a line fault.
• On-board electronics inside the valve, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol E, ISO 4401-08-08-0-05 mounting pattern, NBR seals, 20 kg valve mass.

Application

Intended for large presses and test rigs where several valves share the same pump and tank galleries. Two additional pilot oil lines have to be planned. The 350 bar operating pressure calls for a subplate rated accordingly.
