Beschreibung
Zusammenfassung:	A poppet element of a valve is provided. The poppet element is movable relative to a valve seat of the valve and includes a balance chamber wall defining a balance chamber with a center body partially fixed relative to the valve seat, an upper head, a balance chamber holder having a coefficient of thermal expansion (CTE) that is matched with that of the upper head and a fastening element disposed to fasten the balance chamber holder to the upper head. The balance chamber holder is disposed between the center body and the balance chamber wall and configured to prevent thermal loading transfer from the balance chamber wall to the fastening element.
