Proportional Directional Valve 4WRTE27W8-500L-4X/6EG24ETK31/F1M - Bosch Rexroth R901475343

In sprawling plants the type of signal decides how stable control remains. The 4WRTE27W8-500L-4X/6EG24ETK31/F1M accepts the command value as a current of 4 to 20 mA and uses it to control 500 l/min nominal flow in size 27.

Benefits

• Current command value 4 to 20 mA, insensitive to voltage drop and interference.
• 500 l/min nominal flow, 1000 l/min maximum, operating pressure up to 270 bar.
• Internal pilot oil supply and internal return without additional ports.
• Symbol W8 in three switching positions with internal spool position feedback.
• Weight 19.5 kg, NBR seals, HL hydraulic fluid, supply 24 V DC.

Applications

The valve suits large axes in rolling mills, press lines and special plants whose control cabinet stands far from the hydraulic manifold. A current interface prevents cable length from falsifying the command value. Hydraulically the version is identical to the voltage variant of the same range.
