The invention relates to an air release valve and more particularly to an atmospheric compensating automatic air release valve. The invention features a valve including a second orifice which is exposed to atmosphere but always shut whereby a valve mechanism in the valve is exposed to forces which are equal and opposite to a suction force which tends to hold the valve mechanism in sealing relation to the first, air release orifice. By providing first and second orifices in accordance with the present invention, then, movement of the valve float downwardly as the liquid level goes down will cause the air vent orifice to open irrespective of the pressure within the valve. Thus, the automatic air release. valve provided in accordance with the present invention is capable of operating under virtually unlimited pressures.
