    Abstract: A first secondary valve activated by a float controls through a differential pressure acting on a membrane a main valve in the tank filling duct. The first valve is automatically neutralized to ensure draining of the pipes placed upstream the main valve unless a second secondary valve prevents this neutralization if the level of the receiving tank is beyond a predeterminated level.
