Abstract
The present invention relates to a valve having a control function and a method for controlling a valve in a fluid conduit in order to adapt flow rates and/or differential pressure rates. The valve comprises a fluid inlet and a fluid outlet and a valve closing member located inside a valve body. The valve closing member is operationally connected to a variable volume chamber, which is adapted to extract energy from the fluid in order to provide either an opening or a closing displacement of the valve closing member such that the degree of opening of the valve can be changed. The supply of fluid to and from the variable volume chambers may be regulated by electronically controlled valves.
