Beschreibung
Zusammenfassung:	A gas valve (11) for ventilation which comprises a main body (12) having a first gas chamber (13), a second gas chamber (15) and at least an inlet duct (14) for supplying a gas to the first gas chamber (13). The gas valve (11) further comprises a proportional valve (24) for temporally sealing the first gas chamber (13) from the second gas chamber (15). The second gas chamber (15) comprises at least a second passage opening (22) for releasing the gas from the second gas chamber (15) and the second gas chamber (15) comprises a port (30) for connecting a pressure measurement apparatus for measuring the gas pressure in the second gas chamber (15). A circuit with a ventilation limb which comprises a gas valve (11) and a method for determining a releasing gas flow of a gas valve are also disclosed.
