Size 16 instead of size 25 saves space and weight as long as 220 l/min nominal flow is enough. This 4WRDE weighs 9.2 kg, works at 350 bar and controls the main spool through internal position measurement. The command value arrives as ±10 V.

Not every controlled axis needs size 25, and often 220 l/min from a much smaller valve is sufficient. The size 16 4WRDE offers exactly that at 9.2 kg, 350 bar operating pressure and internal position feedback of the main spool.
Benefits
- 220 l/min nominal flow at only 9.2 kg on the ISO 4401-07-07-0-05 interface.
- Up to 460 l/min maximum flow for short rapid traverse phases.
- Linear characteristic and internal position feedback for repeatable positioning.
- ±10 V command straight from the analogue card of the controller.
- External pilot supply and external return decouple the pilot stage from the working circuit.
- 350 bar operating pressure with on-board electronics and 24 VDC supply.

Applications
The valve is used on feed and positioning axes in machine tools, on test equipment and in special machines with limited space. Because of the smaller interface, replacing a size 25 valve with it requires a new subplate. HL hydraulic fluid with NBR seals is used.
