Summary: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.
