Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900956734

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.

Technical data

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.
