Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/F1V - Bosch Rexroth R900949808

In electrically noisy surroundings the current command is the safe choice. The 4WRZE25W8-325-7X accepts 4...20 mA, meters 325 l/min nominal flow with it and works up to 350 bar operating pressure without any external pilot line being laid.

Benefits

• Current command 4...20 mA, cable length and voltage drop stay uncritical.
• Nominal flow of 325 l/min in size 25, up to 870 l/min maximum.
• Internal pilot supply and internal return keep the piping to P, A, B and T.
• Build without a pressure reducing valve in the pilot stage.
• FKM seals and a mass of 21.16 kg, maximum operating pressure 350 bar.
• UKCA declaration for electromagnetic compatibility to SI2016/1091.

Application

The valve suits welding, forming and testing plants where inverters and power sources load the signal cables. A current command stays steadier there than a voltage signal. Spool symbol W8 with three switching positions covers ordinary four-way operation.
