Where a plant already runs on current loops throughout, the hydraulic valve should be driven the same way. The 4WRZE25E1-220-7X/6EG24N9EK31/F1D3M accepts 4 to 20 mA, releasing 220 l/min rated flow at up to 350 bar.
Benefits
- Command value 4 to 20 mA lets the valve join existing current loop wiring without a converter.
- 220 l/min rated flow at 350 bar, size 25 permits up to 870 l/min maximum flow.
- Spool symbol E1 with 3 switching positions across 4 ports, pilot stage with pressure reducing valve.
- Internal pilot oil intake, external pilot return, 24 V DC through the 7-pole connector (6 + PE) to EN 175201-804.
- Concealed auxiliary actuation, NBR seals, HL fluid, ISO 4401-08-08-0-05, 20.95 kg.

Applications
Valves like this stand in steel plants, paper machines, large test rigs where sensors as well as actuators run on 4 to 20 mA. The 4 mA starting point separates the idle state from a cut cable. A dedicated return channel keeps the pilot stage independent of pressure in the tank line.
