Beschreibung
Zusammenfassung:	The invention relates to a lifting valve having a closing body (5), a valve rod (20) which is connected to the closing body (5), and a lifting drive (8), by means of which a lift of the closing body (5) can be brought about, a drive rod (16) which is operatively connected to the valve rod (20), and a rotational decoupling device (27) which is provided between the valve rod (20) and the drive rod (16). In order to provide a rotational decoupling device (27) of simple construction which is suitable for absorbing great axial loads, it is proposed that the rotational decoupling device (27) comprises at least two shell segments (31, 32), the drive rod (16) has a coupling element (28), and the shell segments (31, 32) form a positively locking connection in the direction of the lifting movement with the valve rod (20) and a positively locking connection in the direction of the lifting movement with the coupling element (28).
