A stage lift has to start slowly and without a jolt, even at full load. The 4WRZE25W8-325-7X/6EG24N9TK31/A1D3M meters 325 l/min nominal flow for that, with spool symbol W8, a ±10 V command value and a weight of 20.7 kg.

In stage engineering every roughness at start-up becomes visible on the platform above. The 4WRZE25W8-325-7X/6EG24N9TK31/A1D3M therefore meters 325 l/min nominal flow under position control, fed from an external pilot circuit with internal return.
Benefits
- A ±10 V command value allows soft ramps straight from the stage control.
- Nominal flow of 325 l/min moves large lifting cylinders in steady travel.
- External pilot oil supply keeps pilot pressure independent of the load on the platform.
- Spool symbol W8 with 3 switching positions secures behaviour at standstill.
- Operating pressure up to 350 bar, ISO 4401-08-08-0-05, 4 ports, weight 20.7 kg.
- UKCA to SI2016/1091, NBR seals, supply 24 V DC.
