Where the valve block already has a ±10 V command signal, the axis can be driven straight from a standard analogue card. This pilot-operated proportional directional valve in size 25 turns that signal into 325 l/min nominal flow, at an operating pressure of up to 350 bar with spool symbol W8.

An analogue card with a ±10 V output is already fitted in many controls. The 4WRZE25W8-325-7X/6EG24N9EK31/A1D3M accepts exactly that signal, metering 325 l/min nominal flow at an operating pressure of up to 350 bar.
Benefits
- Command value ±10 V on the on-board electronics, no extra converter card needed
- 325 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
- Spool symbol W8 with three switching positions across four ports, concealed manual override
- Integrated pressure reducing valve in the pilot stage, internal pilot oil supply with external return
- 20.64 kg weight, UKCA conformity for electromagnetic compatibility SI2016/1091, NBR seals for HL hydraulic fluid
