Abstract:
A valve for conducting fluid under pressure, said valve comprising:an actuation stem for controlling fluid flow through the valve; a valve member having a positioning formation and an opening for permitting fluid flow through the valve member; a one-piece, unitary valve body which encloses the valve member having a first open end with a first diameter; a second open end with a second diameter, which at least during initial assembly of the valve member and body is sufficiently large to permit insertion of the valve member; a stem opening for receiving the actuation stem; and an internal member-receiving portion for receiving the valve member in proximity with the stem opening; and a pair of inserts, each insert including an opening for permitting fluid flow, wherein the valve member is positioned between the inserts, at least one insert having a load applied against it during assembly of the valve, and wherein the valve body is formed about the inserts to provide a seal between the inserts and the valve member and the inserts and the valve body wherein the valve body permanently retains the valve member in the valve body; and whereby the actuation stem is in communication with the positioning formation of the valve member and the flow of fluid through the valve is controlled by the orientation of the valve member within the internal member-receiving portion.
