This version pairs a high 350 l/min nominal flow with spool symbol E1 and the widely used ±10 V command value. A large axis can therefore be controlled from a standard analogue output. Size 25, FKM seals, weight 17.92 kg.

Total price
Large axes often run off the same controller as the small ones and therefore receive ±10 V as their command value. This size 25 valve accepts exactly that signal and turns it into up to 350 l/min nominal flow, with spool symbol E1 and a linear characteristic.
Benefits
- 350 l/min nominal flow controlled straight from an ordinary ±10 V analogue output.
- Spool symbol E1 with linear characteristic, peak flow up to 870 l/min.
- Internal pilot oil supply with external return through Y saves one line of pipework.
- Internal spool position feedback holds the spool even against large flow forces.
- FKM seals, interface ISO 4401-08-08-0-05, weight 17.92 kg.

Applications
The combination is used in plants where axes of different sizes hang off one controller, for example forming lines and test fields. A uniform signal type simplifies spare part stocking and commissioning. System pressure in port P is enough to feed the pilot stage.
