Reinforced plastic valve and method of forming it.

摘要

A reinforced plastic valve includes a generally cylindrical major body portion (14) which is at least partially formed of a plastic material. The major body portion (14) has an axially extending interior chamber (16). A pair of flow lines (18) intersect the major body portion (14) and the interior chamber (16) thereof. A plug (22) is mounted in the chamber (16) and is selectively rotatable to control flow of fluid through the flow lines (18). The major body portion (14) includes a reinforcing sleeve (48) formed of metal which is encased within the plastic major body portion (14) to surround the interior chamber (16).
