<p>A fully automatically operable pneumatic stop valve is provided which rests on the principle of pressure differences in its various membrane spaces in controlling the fluid flow through the valve, wherein the rising fluid closes a fluid level control pipe and thereby upsets the pressure conditions in an auxiliary valve membrane space which in turn controls the pressure in the main membrane space controlling the closing of the main valve.</p>
