7 DISMANTLING AND REASSEMBLY OF
VALVES
7.1 GENERAL
Keep a spare oiled and maintained set of valves in store for quick compressor servicing.
Valves should have a thin carbon layer and be slightly moist with oil.
Valve removal is a simple procedure but the following guidelines should be observed.
7.2 CLEANING AND INSPECTION
– ALL STAGES
The valve components should be degreased using a suitable solvent and stiff brush. Carbon deposits
may be removed scraping with a soft, blunt instrument, e.g. a piece of wood.
WARNING!
GREAT CARE SHOULD BE TAKEN WHEN REMOVING CARBON DEPOSITS TO
ENSURE THAT THE SEATING FACES OF THE VALVE COMPONENTS ARE NOT
DAMAGED.
These faces should be clean and bright over their whole area, with no evidence of uneven contact.
Renew any plates which are indented, cracked, warped, or have wear grooves.
If the seats show severe wear or indentations the complete valve assembly must be renewed. The
remaining components should be checked for cracks, distortion or other damage liable to impair valve
operation.
