METHOD FOR RECOGNIZING A VALVE MODEL OF A VALVE AND VALVE ARRANGEMENT PROVIDED FOR CARRYING OUT THE METHOD

The present inventions pertains to a method for recognizing a valve model of a valve (7) connected to an actuator (1) with a valve controller (11), the valve comprising a valve element (2) for closing and opening a valve passage (3), wherein the valve element is in permanent contact with a non-translated spindle (4) via threaded portions (21, 41), wherein the spindle is provided for transmitting only rotational movement between the actuator and the valve element for generating a relative movement between the valve element and the spindle during the opening and closing of the valve, wherein the method recognizes the model of valve by the maximum allowable valve element stroke. The invention also pertains to a valve arrangement comprising a valve and an actuator with a valve controller, the valve comprising a valve element for closing and opening a valve passage. The valve arrangement is provided for carrying out the previously described method.
