A respirator directional valve () includes a valve housing (), a plurality of valve flaps (-), which can be moved by a gas stream or by a flowing medium and are arranged at the edge, and a number of support surfaces (-) as a valve seat. A number of support surfaces (-) corresponds to a number of valve flaps (-). Each valve flap (-) is adapted to a surface of a respective support surface (-). The support surfaces (-) are sloped in relation to a cross-sectional surface through the valve housing (). The support surfaces (-) together form a tip pointing in the flow direction of the respirator directional valve (). A method for manufacturing such a respirator directional valve () is provided including method features relating to the use of such a respirator directional valve ().
