Abstract
The valve includes a rubber gasket which is clamped and sealed to the sheet metal vessel of a fuel/water separator by a rivet nut and which serves as a seat for the valve head of a valve member that is screwed into the rivet nut. When the valve member is opened, the valve head moves upwardly away from the gasket to allow air to enter the vessel through one passage in the valve member and to enable liquid to drain from the vessel through a separate passage in the valve member. The valve member may be formed as two die cast parts which interfit with one another to define the passages and which eliminate the need of machining the passages. Alternatively, the valve member may be a single die cast part with internal passages, there being a die cast operating knob attached to the valve member.
