A method for partially stroking an emergency valve apparatus is provided. The emergency valve apparatus comprises an actuator (103) and a valve member (101). The apparatus is movable between a first position and a second position. The method comprises the step of initiating a partial stroke movement of the apparatus from the first position towards the second position. A parameter of the fluid acting on the apparatus is measured. Once the measured parameter reaches a threshold value, the partial stroke movement is reversed. L'invention concerne un procédé pour déplacer partiellement un appareil de soupape d'urgence. L'appareil de soupape d'urgence comprend un actionneur (103) et un élément de soupape (101). L'appareil peut se déplacer entre une première position et une seconde position. Le procédé comprend l'étape de lancement d'un mouvement de déplacement partiel de l'appareil de la première position à la seconde position. Un paramètre du fluide agissant sur l'appareil est mesuré. Une fois que le paramètre mesuré atteint une valeur de seuil, le mouvement de déplacement partiel est inversé.
