Proportional Directional Valve 4WRTE25W6-350L-4X/6EG24ETK31/F1V - Bosch Rexroth R901207007

In circuits where both pump pressure and return pressure swing widely, the pilot stage should be independent of both. The 4WRTE25W6-350L-4X/6EG24ETK31/F1V therefore routes pilot oil supply and drain externally while metering 350 l/min nominal flow at 350 bar operating pressure.

Benefits

• External pilot oil supply and external pilot oil drain separate the pilot stage from the working circuit.
• 350 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• A 4...20 mA current command for plants with long signal runs.
• Spool symbol W6 with three switching positions across four ports, ISO 4401-08-08-0-05 mounting pattern.
• 350 bar operating pressure, FKM seals, 17.9 kg valve mass, 24 VDC supply.

Application

Intended for complex manifolds where several large valves share pump and tank. Both pilot oil lines have to be laid separately. That effort pays off where control quality would otherwise suffer from pressure fluctuations.

Manufacturer

Bosch Rexroth lists this valve under material number R901207007. Seals are FKM and matched to HL hydraulic fluid.
