Abstract
A gas shut-off valve for installation in gas meters, has a valve disk that can be moved in the longitudinal direction with respect to its valve seat. The movement is realized by a linear unit held in the longitudinal direction in a valve casing, which is actuated by an electric motor via reduction gearing. The valve seat has a lip seal. The electric motor is a small DC motor. The reduction gearing and the linear unit, are installed in a panel of the valve casing. The linear unit is a rack-and-pinion gearing or a sliding-screw gearing, having an adjusting-nut element and an adjusting rod.
