ABSTRACT:
A rivet-type flapper valve assembly for a fluid device has a main body part defining a valve orifice communicating with the fluid device. The main body part includes a pin or shaft of a rivet spaced adjacent to the valve orifice. The main body part is permanently attached to the fluid device, such as by brazing. A flapper valve is then mounted on the rivet shaft to cover the valve orifice, and the rivet shaft is deformed to retain the flapper valve in place.
