According to this 1970s catalog, asbestos was a common material for valve packing and gaskets. Here are specific references:
The page on valve packing has a paragraph about "Endless Molded Ring Packing" which says: "Basic ingredients are asbestos impregnated with 30 to 35% TFE (tetrafluoro-ethylene) for use up to 366 F or an asbestos-graphite mixture for use up to 550 F."
Injection Type Packing is also described as containing asbestos. It says: "The center core and injection pellets consist of an homogenous mixture of asbestos fibre, TFE, and other ingredients..."
The section on "Diagonally Cut Die-Formed Ring Packing" has further description of asbestos contained packing materials.
The page on valve gaskets has an illustration of a flat asbestos gasket.
The valve gaskets page mentions asbestos as one of the fillers for spiral-wound gaskets.
