Proportional Directional Valve 4WRDE27W6-500L-6X/VXY/24A5 - Bosch Rexroth R901545431

Once the oil runs hot or another medium is used, the seal material decides service life. This 4WRDE27W6-500L-6X/VXY/24A5 works with FKM seals, carries spool symbol W6, plus controls 500 l/min nominal flow at 270 bar operating pressure.

Key benefits

• FKM seals instead of NBR are rated for higher oil temperatures in continuous duty.
• Spool symbol W6, a special stage within the 4WRDE series, on 3 switching positions.
• Nominal flow of 500 l/min, peak flow of 1000 l/min, operating pressure of 270 bar.
• External pilot oil supply with external return plus on-board electronics on a plus or minus 10 V command.
• Interface ISO 4401-08-08-0-05, mass of 19.5 kg, 7-pole connector.

Applications

Foundries, hot forming plants plus systems running at raised oil temperature ask for this build. Spool symbol W6 defines a different centre position that has to match the safety concept of the axis. HL hydraulic fluid is recorded in the data set.

Manufacturer

Bosch Rexroth lists the build as 4WRDE27W6-500L-6X/VXY/24A5 under material number R901545431. Spool symbol plus seal material are fixed at build time, a change to NBR happens only through a different material number.
