As they are constantly in motion - and this under difficult tribological conditions and under the effect of aggressive gases or exhaust gases - they are subject to natural wear. This can be accelerated due to extreme conditions such as mechanical or thermal overloads. Valves must therefore generally be replaced when any sign of damage is noticeable.
