Long signal runs between cabinet and valve distort a voltage, but not a current. This valve takes its command as 4...20 mA and converts it into 350 l/min nominal flow at up to 350 bar. Spool symbol E1, external pilot oil routing, weight 17.94 kg.

Where many metres of cable separate cabinet and valve, a current signal is the safer choice. The 4WRTE25E1-350P-4X/6EG24K31/F1M accepts its command as 4...20 mA and turns it into up to 350 l/min nominal flow at 350 bar operating pressure.
Benefits
- A 4...20 mA command stays insensitive to voltage drop over long cable runs.
- 350 l/min nominal flow with spool symbol E1 and 3 switching positions.
- Internal spool position feedback holds the characteristic curve across the full range up to 350 bar.
- External pilot oil supply and external return decouple the pilot stage from the working circuit.
- A 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC, mounting pattern ISO 4401-08-08-0-05, 17.94 kg.

Applications
The valve fits sprawling plants such as rolling mills, lock gate drives and large presses where the control cabinet sits far from the valve block. A broken wire shows up in the signal itself, because the range starts only at 4 mA. Pilot supply stays separate from working pressure.
Manufacturer
