Proportional Directional Valve 4WRZE25E325-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954672

Spool symbol E and internal piloting belong together here: the 4WRZE25E325-7X/6EG24ETK31/A1D3M draws pilot oil from the main circuit, returns it internally and meters 325 l/min nominal flow at an operating pressure of up to 350 bar.

Benefits

• Spool symbol E, centre position closed as defined by the associated switching symbol.
• Internal pilot oil supply and internal return, so piping stays limited to four lines.
• Nominal flow 325 l/min, up to 870 l/min possible through the valve.
• Operating pressure up to 350 bar, mounting pattern ISO 4401-08-08-0-05, size 25.
• Analog ±10 V command value at the on-board electronics, 24 VDC through a 7-pole connector (6 + PE).
• NBR seals for HL hydraulic fluid, mass 20.42 kg.

Applications

The variant is used on lifting and pressing axes that must stand safely between cycles. Because the pilot stage is fed internally, the installation needs no extra pilot line. In exchange the main circuit has to stay pressurised during operation.
