Proportional Directional Valve 4WRZE25E325-7X/6EG24K31/A1D3M - Bosch Rexroth R900954673

External pilot oil supply and external pilot oil return keep control quality independent of what the main circuit pressure does. The 4WRZE25E325-7X/6EG24K31/A1D3M meters 325 l/min nominal flow at 350 bar and switches through symbol E in three positions.

Benefits

• External pilot oil supply and external return, steady piloting even when the main circuit is unloaded.
• Nominal flow 325 l/min, with up to 870 l/min possible through the valve.
• Spool symbol E with the centre position closed as defined by the associated switching symbol.
• Operating pressure up to 350 bar on the size 25 mounting pattern ISO 4401-08-08-0-05.
• On-board electronics for the analog ±10 V command value, 24 VDC supply.
• 7-pole connector (6 + PE) to EN 175201-804, mass 20.62 kg.

Applications

The version fits plants whose main circuit is unloaded from time to time, for example presses with relief phases. A separate pilot circuit still holds the spool in position. Pilot supply and return must be provided on site.
