Abstract

1. A device for holding a driving stem of a valve fitting at a preselected stroke setting, the driving stem being operated by way of a rotatable non-rising drive bush (7), comprising a threaded ring (13), which surrounds the bush and which, after the engagement of a sliding element (15) in axially extending recesses (16) provided within the actuating mechanism, may be moved upwards and downwards by turning the driving bush (7) within a locking housing (3) attached to the bonnet of the valve fitting and is able to be axially locked by way of a latch (11) to be operated by means of a key (10), characterized by the combination of the following features : a) the threaded ring (13) is provided with a male thread and may be turned within a female thread (14) in the locking housing (3) and is arranged so as to be able to move upwards and downwards, b) the sliding element has the form of a key (15), is detachably mounted in the threaded ring (13) and fits into one of a plurality of circumferential spaced axial recesses (16) in the driving bush (7), c) the key (15) and the means of attaching it are accessible by way of an opening which is provided in the locking housing (3) and may be closed, and d) the threaded ring (13) is provided with an aperture (12) into which there may be fitted a locking bolt (11), which is adapted to have an interlocking shape, for providing a locking action in the axial and circumferential directions.
