Abstract
A reinforced plastic valve includes a generally cylindrical major body portion which is at least partially formed of a plastic material. The major body portion has an axially extending interior chamber. A pair of flow lines intersect the major body portion and the interior chamber thereof. A plug is mounted in the chamber and is selectively rotatable to control flow of fluid through the flow lines. The major body portion includes a reinforcing sleeve formed of metal which is encased within the plastic major body portion to surround the interior chamber.
