A pressure independent control valve contains a valve body with an inlet, an outlet and a flow channel coupling the inlet to the outlet. A hollow piston is arranged in a seat in the valve body, such that the hollow piston is configured to move. The hollow piston has an enclosure, such that the pressure independent control valve maintains different fluid pressures in the flow channel and inside the hollow piston. The pressure independent control valve contains a chamber and a biasing member to urge the hollow piston towards the chamber. The chamber is in fluid communication with the inlet and with the inside of the hollow piston, such that the valve applies substantially the same pressure inside the annular channel, at the inlet and inside the hollow piston.
