Proportional Directional Valve 4WRTE27W8-500L-4X/6EG24K31/F1M - Bosch Rexroth R901097371

Existing plants usually dictate the pilot circuit and the signal type, so a replacement valve has to fit in. The 4WRTE27W8-500L-4X/6EG24K31/F1M does that with external pilot oil supply, external return, symbol W8 and 500 l/min nominal flow.

Benefits

• External pilot oil supply and external return, as commonly found in grown installations.
• Symbol W8 with three switching positions and internal spool position feedback.
• 500 l/min nominal flow, 1000 l/min maximum, operating pressure up to 270 bar.
• Current command value 4 to 20 mA, supply 24 V DC, 7-pole connector (6 + PE).
• Weight 19.46 kg, HL hydraulic fluid, mounting pattern ISO 4401-08-07-0-05.

Applications

The valve replaces equivalent valves on presses, stretching lines and large lifting axes without changes to piping or wiring. A pilot circuit with its own supply and drain is required. Symbol and nominal flow should be checked against the hydraulic schematic before the swap.
