Abstract
The present invention pertains to a stepper motor actuated active balancing valve for a refrigeration and/or air-conditioning application. The valve comprises a valve housing with an inlet orifice, an outlet orifice and a mounting portion, a main valve element with a main pressure balance orifice and a control element at least partially defining a pressure balance passage. Each element is slidable inside the valve housing and comprises a control surface for controlling a fluid flow between the inlet orifice and the outlet orifice and/or pressure propagation between the outlet orifice and the inside of the main valve element. The control element closes the main pressure balance orifice of the main valve element in a closed state of the valve.
