GEA Westfalia 0018-6654-000 Solenoid Valve Assembly: Genuine OSD Separator Component
This GEA Westfalia Separator 0018-6654-000 solenoid valve assembly is a control valve for Westfalia OSD-series mineral oil separators. This solenoid valve unit controls the operating water pathways used to trigger precise bowl opening and shutting mechanisms during automatic sludge ejection cycles. It is a genuine OEM unit manufactured to precise marine and industrial fluid-handling specifications that prevents the pressure drops, improper de-sludging cycles and coil burnout sometimes experienced with aftermarket replacements.

Key Features of the 0018-6654-000 Assembly
- Optimised Hydrodynamic Response: Designed to deliver the exact millisecond response time required to commence a clean, crisp bowl desludging action without wasting water or losing valuable product oil.
- Marine-Grade Environmental Resistance: The electrical solenoid coil blocks are constructed using advanced insulation materials to survive engine room ambient temperature over 55°C, high humidity and oily atmospheres.
- Zero Leakage Internal Sealing: High class elastomeric seals preventing the constant leaking of raw or fresh water into the purifier closing-water chamber and hence unwanted intermediate ejections.
- Zero Field Modifications: Direct manifold mounting design is a perfect match for OSD operating water blocks. No pipe rethreading or bracket fabrication required.
- Extended Mechanical Service Life Internal armatures, springs and guide tubes are made of hard-wearing stainless steel resistant to scaling, pitting and mineralisation from untreated fresh water supplies.
Marine Applications
- Operating Water Control Networks : Controls the precise distribution of water for opening and closing of the bowl sliding operation.
- Marine Diesel Fuel Conditioning Applied to HFO (Heavy Fuel Oil) and MDO (Marine Diesel Oil) separator modules on commercial vessels, bulk carriers, and supply ships.
- Lube Oil Reclamation Systems Supplies lube oil cleaning loops for the main propulsion engine and auxiliary generator.
