Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900940842

Anyone keeping the manifold lean picks the build with internal pilot supply and internal return. The 4WRZE25W6-325-7X does without additional X and Y lines while metering 325 l/min nominal flow at up to 350 bar operating pressure.

Benefits

• Internal pilot supply and internal return, the external X and Y ports are not needed.
• Nominal flow of 325 l/min, 870 l/min at peak.
• Voltage command ±10 V, taken straight from ordinary analogue controller outputs.
• Build without a pressure reducing valve in the pilot stage, matched to circuits with steady system pressure.
• FKM seals for higher oil temperatures, spool symbol W6.
• Mass of 20.2 kg, connection diagram ISO 4401-08-08-0-05, UKCA declaration.

Application

Applications are lift and slew axes on test rigs, press feeders and power units with little room for piping. Since no pressure reducing valve is fitted in the pilot stage, system pressure should not drop below the required pilot pressure during operation. FKM seals allow service on plants running hot.
