3.4. Valve stem seals

When it comes to fugitive emission considerations, valve stem seals are known as the most important leakage points for two reasons. First, valve stem seals are categorized as dynamic seals due to the movement of the stem. Second, unlike the valve seat or seat insert, leakage from the valve stem seals is released to the environment and is a main source of fugitive emission. Thus, it is worth focusing in more detail on valve stem seals, including their materials and arrangements, as well as their effects on valve operation.
