A smaller nominal flow in the same size buys resolution per command step. The 4WRZE32 with symbol W8 is rated at 360 l/min at 350 bar and still passes up to 1600 l/min. Command value ±10 V, weight 43.1 kg.

Positioning a large axis accurately often works better with a smaller nominal flow. The 4WRZE32W8-360-7X is rated at only 360 l/min in size 32 and gains resolution that way, at 350 bar operating pressure.
Benefits
- 360 l/min nominal flow in size 32, for a finer relation between command value and movement.
- Up to 1600 l/min maximum flow, so the frame still carries rapid traverse phases.
- Symbol W8 with three switching positions and four ports.
- External pilot oil supply and external return, command value as a ±10 V voltage.
- 43.1 kg weight, 350 bar operating pressure, NBR seals, connection diagram ISO 4401-10-09-0-05.
