Proportional Directional Valve 4WRTE27V500P-4X/6EG24EK31/F1M - Bosch Rexroth R901185058

In cabinets crowded with frequency converters, interference couples easily into voltage signals. This version of the 4WRTE27V500P therefore takes the command value as a 4 to 20 mA current and controls 500 l/min nominal flow with external pilot return.

Benefits

• Command value 4 to 20 mA, more robust than a voltage signal in an electrically noisy environment.
• Internal pilot supply, external pilot return, independent of back pressure in the return line.
• 500 l/min nominal flow, up to 1000 l/min in size 27.
• Spool symbol V with a fine control range and internal piston position feedback.
• 270 bar operating pressure, NBR seals, hydraulic fluid HL.
• 19.32 kg weight, connection diagram ISO 4401-08-07-0-05.

Applications

The version makes sense on machines with many drives in a tight space, such as forming lines and test benches. The on-board electronics accept the current signal directly. Pilot oil returns to tank through a separate line.
