Abstract
A lift valve having a valve housing and a stroke drive is described. The stroke drive includes a drive rod that can be moved along a stroke axis into a first and a second end position. A measuring apparatus is coupled to the stroke drive on a side of the stroke drive facing away from the valve housing and includes a first sensor, a second sensor, and a first transducer. The first transducer is arranged to follow the movement of the drive rod and is arranged on a sensor rod arranged in an end region of the drive rod. To achieve a compact and safe design, a second transducer is arranged to follow the movement of the drive rod, the first sensor is arranged between the second sensor and the stroke drive. The first sensor is excited by the second transducer, which is arranged on a side of the first transducer facing the drive rod, when the drive rod is in the second end position.
