Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900956734
Internal pilot supply with an external drain: the 4WRZE25E1-325 in the A1D3V build routes pilot oil to tank through its own Y line without back pressure. Nominal flow 325 l/min, 870 l/min at peak, maximum 350 bar and FKM seals.

Description
If the return line carries back pressure, pilot oil must not join it. The 4WRZE25E1-325-7X in the A1D3V build takes pilot oil internally and drains it to tank through the separate Y port, at 325 l/min nominal flow and up to 350 bar.
Benefits
- External pilot drain keeps the pilot circuit clear of back pressure in the tank line.
- Internal pilot supply, an additional X port is not needed.
- Nominal flow of 325 l/min, maximum flow 870 l/min at 350 bar.
- Pressure reducing valve in the pilot stage for steady pilot pressure.
- FKM seals, spool symbol E1, concealed manual override.
- Mass of 20.58 kg, connection diagram ISO 4401-08-08-0-05, command value ±10 V.
Application
This variant belongs in circuits with a return filter or cooler, where the tank line is pressurised. It is also the right pick when replacing older valves in manifolds that already have a Y port. The FKM seals cope with permanently hot oil.
