Proportional Directional Valve 4WRZE25E325-7X/6EG24EK31/A1D3M - Bosch Rexroth R901094959

High flow and fine resolution do not exclude each other when the spool brings a pronounced fine control range. The 4WRZE25E325-7X/6EG24EK31/A1D3M uses spool symbol E for that and carries 325 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Spool symbol E combines 325 l/min nominal flow with fine resolution in the lower command range.
• Internal pilot oil supply with external return means only one extra line.
• A built-in pressure reducing valve holds pilot pressure constant although it comes out of working pressure.
• A plus or minus 10 V command matches existing analogue outputs without a converter, supply 24 VDC.
• UKCA conformity to SI2016/1091, mounting pattern ISO 4401-08-08-0-05, weight 20.68 kg.

Technical data

Applications

The valve controls press axes and hoists that have to travel fast and then stop to the millimetre. An external pilot return keeps the pilot circuit clear of back pressure in the tank line. Range maximum flow amounts to 870 l/min.
