What is valve lapping compound used for?
Lapping pastes are used for controlled removal and are used for the close mating of surfaces and for removing rust and the brightening of a metal surface. They are used for lapping of the exhaust and the inlet valves of engines, seat repairs of globe valves, the overhaul of reciprocating compressor valves, etc.
What does it mean to lap a valve?
To lap a valve you put carborundum paste between the valve and its seat. By turning the valve back and for the paste erodes any high points so that there is a smooth connection and excellent seal between the valve and its seat.
