ABSTRACT:
A flapper valve assembly has a valve plate for attachment to a fluid device, such as a heat exchanger. The valve plate has a fluid port for permitting intermittent flow to or from a flow chamber in the fluid device. A resilient flapper covers the fluid port and has at least one transverse tab with resilient, laterally disposed tangs, so that the tabs snap into slots in the valve plate to prevent rotation of the flapper.
