In a foundry plant the return line builds up pressure across coolers and filters. The 4WRTE10E50L-4X/6EG24EK31/F1M therefore returns pilot oil externally, draws it internally and controls 50 l/min nominal flow through spool symbol E from a 4...20 mA command.

Back pressure in the tank return shifts the characteristic of a valve with internal pilot oil return. The 4WRTE10E50L-4X/6EG24EK31/F1M avoids that through a dedicated Y port while metering 50 l/min nominal flow from the 4...20 mA current command.
Benefits
- Nominal flow 50 l/min in size 10, throughput up to 170 l/min.
- Spool symbol E with three switching positions across four ports.
- Command value 4...20 mA at the on-board electronics, 24 V DC supply.
- Internal pilot oil supply, external pilot oil return, fixed in the type code.
- Operating pressure to 350 bar on connection diagram ISO 4401-05-05-0-05.
- NBR seals, 8.48 kg, 7-pole connector (6 + PE) to EN 175201-804.
