A drain valve (10) is described comprising a housing (11), a fluid inlet (12), a gas outlet (13) and at least one liquid outlet orifice (19) arranged in a liquid outlet member (20) of the housing (11). The drain valve (10) furthermore comprises a float (16) connected to a lever (17) on a first end (18). The float (16) is arranged in a float chamber (15) of the housing (11). The float chamber (15) is connected to the fluid inlet (12), the gas outlet (13) and the at least one liquid outlet orifice (19). The liquid outlet orifice (19) may be opened or closed by a closing member (21) that is connected to a second end (22) of the lever (17) and is rotatably connected to the liquid outlet member (20). If a liquid is arranged in the float chamber (15) a rise in the liquid level will result in a lift of the float (16) whereby the closing member (21) is rotated to a more open position of the at least one liquid outlet orifice (19) and vice versa. Such a drain valve should be operated at higher fluid pressures without increasing the size of the valve. To this end the liquid outlet member (20) comprises a cylinder-like section and the closing member (21) is arranged concentrically around the cylinder-like section, wherein the closing member (21) comprises a closing element (24), wherein in the open valve position of the closing member (21) the closing element (24) converges towards the closest liquid outlet orifice (19) that the closing element (24) is matched to such that the surface of the closing element (24) perpendicular to the liquid flow direction through the liquid outlet orifice (19) is minimized, and the end of the liquid outlet orifice (19) that is first exposed when the liquid outlet orifice (19) is opened has the smallest width perpendicular to the opening direction of the closing element (24).
