For very large cylinders what counts is the flow a valve will pass at all. This size 25 valve of the 4WRLE range takes up to 1250 l/min and meters at 400 l/min nominal flow with internal spool position feedback. Command value ±10 mA, operating pressure up to 350 bar.

Once a cylinder in rapid traverse demands more oil than a normal directional valve will pass, the flow figure becomes the selection criterion. This size 25 valve passes up to 1250 l/min, meters at 400 l/min nominal flow and holds spool position through internal position feedback.
Benefits
- Flow up to 1250 l/min through the valve, nominal flow 400 l/min.
- Internal spool position feedback keeps spool travel tied to the command value.
- External pilot oil supply and external return, independent of the working circuit up to 350 bar.
- ±10 mA command value at the on-board electronics, 24 VDC supply.
- Spool symbol V, 4 ports, 3 switching positions, ISO 4401-08-08-0-05, weight 19.36 kg.
- NBR seals for HL hydraulic fluid, CE conformity.
