ABSTRACT:
The valve assembly comprises a body formed of substantially identical, or identical plates, in which one is the mirror-image or reverse of the other. The plates are held apart, in parallel planes, by an enveloping seal. Each plate is ported for the conduct of fluid therethrough in cooperation with a fluid-conducting void formed in the confronting plate. Flapper-type valving elements are confined within the body, between the plates. A single, centrally-disposed fastener secures the plates and the assembly together, and constitutes the means for the simple disassembly of the unit.
