Abstract
A flapper valve assembly attaches to a fluid device, such as a heat exchanger and has a fluid port in communication with the fluid device to provide by-pass flow in cold flow or pressure spike conditions. The flapper valve assembly includes a shim plate and a face plate that together define a slot therebetween. A spring flapper slides into the slot and is retained therein and intermittently blocks flow through the fluid port to provide the by-pass flow when required.
