Abstract
An adjustable lock for rotating drives, more particularly pipework fittings such as screwdown valves, gate valves or the like wherein the drive is required to make a number of revolutions. In the adjustable lock, a planetary transmission is provided as a reducing transmission in order to reduce drive rotation to at most one revolution and, therefore, to define a definite locking position.
