Proportional Directional Valve 4WRZE25W6-220-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901106936

Four main ports and one cable are enough for this version. The 4WRZE25W6-220-7X/6EG24ETK31/F1D3M routes pilot feed and return internally, accepts a 4...20 mA command and provides 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Fully internal pilot routing means no additional lines have to be laid.
• A 4...20 mA command saves a screened voltage cable running to the valve.
• Spool symbol W6 with 3 switching positions and 220 l/min nominal flow in size 25.
• A built-in pressure reducing valve keeps the pilot stage at constant pressure despite internal supply.
• UKCA conformity to SI2016/1091, NBR seals, weight 20.56 kg.

Technical data

Applications

The version suits compact control blocks on motor drives and through-rod cylinders that offer neither room nor ports for a pilot circuit. Since pilot pressure comes out of working pressure, that pressure has to stay applied. The tank line should carry as little back pressure as possible.
