Abstract
A movable valve member is disposed within a first stage regulator within a regulator body for receipt of pressurized gas. The movable valve member is formed of a metal having an enlarged head and an attached stem with a shoulder integral with the stem adjacent the enlarged head. Surrounding the head and extending peripherally is an elastomeric or plastic material. A support washer is pressed over the shoulder against the plastic molded surface and is frictionally engaged to support the elastomeric or plastic material. A process for making the movable valve member is also provided.
