English to German Tech/Engineering Mechanics / Mech Engineering Hydraulik

Es geht um ein Wegeventil:
"The solenoid operated directional control valves are of wet-armature design and are rated at 3000 psi."
"Most of the solenoid coils used for operating the hydraulic valves are of electric type and wet armature design. Comparing with air gap solenoid, wet armature solenoid design has increased reliability as a result of better heat transfer characteristics and the elimination of pushpin seals, which have a tendency to leak".

Ich habe ein paar Erläuterungen gefunden, aber wie nennt man das auf Deutsch?

Vielen Dank im voraus.
