In systems with a dedicated pilot circuit, pilot oil supply and return are consistently taken outside. The H-4WEH25C6X/6EG24NK4 is built that way, carries spool symbol C and switches up to 700 l/min at a maximum of 350 bar.

Application
Valves of this kind sit in manifolds of presses and lifting gear whose pilot pressure comes from a small auxiliary pump. Pilot pressure is therefore kept even when the working pressure collapses. Wiring runs through a 3-pole connector (2 + PE) to EN 175301-803.
