Abstract
A valve for controlling fluid flow is provided. The valve includes an actuating stem for controlling the flow of fluid through the valve, a valve member with a positioning formation and an opening for permitting fluid flow, a valve body portion, and at least one insert or compressor for retaining the valve member within the valve body portion. The valve body portion is comprised of a formable material—such as a metal—that is formed about the valve member in connection with an applied load. The valve body portion further includes a first open end with a first diameter; a second open end with a second diameter that is sufficiently large enough 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. 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. A method for forming a valve is also disclosed.
