ABSTRACT:
In a valve having a mechanically journalled movable element for regulating the valve's degree of opening, and in a method for controlling such a valve, the movable element and journals are made to move in relation to each other in order to reduce friction in the journals of the movable element. The movable element is then in a position governed by the valve's prevailing degree of opening.
