Proportional Directional Valve 4WRZE25E325-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901366139

The pilot stage is the most sensitive part of such a valve, because its nozzles react to dirt and to pressure swings. This version therefore takes pilot oil externally from a filtered circuit, reduces it inside the valve and moves 325 l/min with spool symbol E.

Benefits

• External supply X from a dedicated, filtered control circuit.
• A pressure reducing valve in the pilot line keeps pilot pressure independent of the level in that circuit.
• Internal pilot drain, which keeps it at one line to the outside.
• Nominal flow 325 l/min, operating pressure up to 350 bar, spool symbol E.
• Plus/minus 10 V command, on-board electronics on 24 VDC, mass 20.58 kg.

Applications

Plants with their own pilot oil conditioning are found in rolling mills, hydro power stations and large test rigs where filtration grade and oil temperature are monitored. The valve fits in there without an extra reducing stage in the manifold. The drain runs internally into the tank channel.
