Abstract
A pneumatic control valve comprises a position controller and a valve which is influenced by the controller. A valve member can be lifted by means of a servomotor which is securely connected to the valve housing by means of a yoke, the servomotor being connected to the valve member by means of a valve rod. The lift position of the valve rod is sensed by means of a rotatable lever of the position controller, which rotatable lever is in a working connection with the valve rod by means of an articulated device. A housing encloses the valve rod, the lever and the articulated device.
