When the control system of an installation moves from a voltage to a current command, the hydraulics should stay untouched. The 4WRTE16W8-220L-4X/6EG24ETK31/F1M takes over the axis on 4...20 mA, keeps hole pattern and piping and meters 220 l/min nominal flow at up to 350 bar.
Benefits
- 4...20 mA command value on an otherwise unchanged subplate mounting to ISO 4401-07-07-0-05.
- Internal pilot oil supply and internal pilot oil return, no change to the manifold.
- 220 l/min nominal flow, maximum flow 460 l/min in size 16.
- Spool symbol W8 with a linear characteristic curve, operating pressure up to 350 bar.
- 24 VDC supply on a 7-pole (6 + PE) connector to EN 175201-804, 11.22 kg weight.

Applications
The valve is chosen during modernisation of presses, sawmills and forming lines whose control system is being replaced. Because hole pattern, connector and pilot routing stay the same, the conversion is limited to wiring. At 220 l/min axis performance matches the previous design.
