Proportional Directional Valve 4WRZE25W8-325-7X/6EG24ETK31/A1V - Bosch Rexroth R901272413

Where system pressure in the circuit is steady anyway, the pressure reducing valve in the pilot stage can be dropped. The 4WRZE25W8-325-7X in the A1V build uses that simpler layout and meters 325 l/min nominal flow at up to 350 bar operating pressure.

Benefits

• Layout without a pressure reducing valve in the pilot stage, fewer parts in the pilot path.
• Internal pilot supply and internal return, four main lines are enough.
• Nominal flow of 325 l/min, maximum flow 870 l/min.
• Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
• FKM seals and spool symbol W8, mass 20.22 kg.
• Connection diagram ISO 4401-08-08-0-05, UKCA declaration to SI2016/1091.

Application

The build fits power units with a pressure controlled pump or an accumulator, where system pressure hardly collapses. FKM seals allow continuous duty at raised oil temperature. Spool symbol W8 covers ordinary four-way operation with three switching positions.
