ABSTRACT:
A valve assembly includes a valve body with an inlet, an outlet, and a chamber extending between the inlet and the outlet and an actuation sub-assembly. Positioned in the chamber is a flow restrictor, which is positionable between a valve open position wherein the fluid communication between the inlet and outlet is open and a valve closed position wherein the fluid communication between the inlet and the outlet is closed. The actuation sub-assembly includes a stem for engaging the flow restrictor. When the actuation sub-assembly is mounted to the valve body, the stem extends through the valve body wall for engagement with an engagement surface of the flow restrictor but is removable from engagement with the engagement surface of the flow restrictor without requiring disassembly of the valve body.
