Paper machines as well as dryer sections are often wired over long distances. The 4...20 mA current command of this 4WRZE 25 helps there. It meters 220 l/min at 350 bar, takes pilot oil internally, returning it externally to tank.

The command value is handed over as a 4...20 mA current, which renders voltage drop plus pickup on long cables harmless. From it the valve produces 220 l/min nominal flow, at 350 bar operating pressure with an 870 l/min flow limit.
Benefits
- Current interface 4...20 mA, noise resistant across wide cable routes
- 220 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
- Internal pilot oil supply, external pilot oil return
- Spool symbol W6, 3 switching positions, 4 ports, concealed manual override
- FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.28 kg
