In a method for controlling a valve having a mechanically journalled (14, 16) movable means (8) for regulating the valve's degree of opening, the movable means and bearings are made to move in relation to each other in order to reduce friction in the bearing of the movable means. The movable means is then in a position governed by the valve's prevailing degree of opening. In an electromagnetic valve, whose degree of opening is adjustable by a movable means in a mechanical bearing (14, 16), a movement device (24) in arranged to impart a relative movement to the movable means in an opening position determining the valve's prevailing degree of opening. <IMAGE> |
