Description
High back pressure in the tank return can disturb pilot operation. This size 25 version therefore feeds pilot oil in externally and returns it externally, switching up to 700 l/min in spool symbol E.
Benefits
- External pilot oil supply and external pilot oil return, independent of the main tank return
- 700 l/min maximum volume flow at 350 bar maximum operating pressure
- Spool symbol E with three switching positions across four ports
- 24 V DC supply, 3-pole (2 + PE) connector to EN 175301-803
- 19 kg weight, NBR seals, mounting pattern ISO 4401-08-08-0-05
Application
The variant is used in plants with long return lines or filters in the tank run, where back pressure builds up. A dedicated pilot circuit keeps switching times stable. It mounts on a size 25 subplate.
