Abstract
A gas valve for a cooking appliance is provided and includes a valve housing defining a valve chamber therein. A plug is disposed within the valve chamber. A valve stem interacts with the plug such that rotation of the valve stem correspondingly rotates the plug to selectively permit a flow of gas through the gas valve. The valve stem is axially translatable between a locked position wherein rotation thereof is inhibited and an unlocked position wherein rotation thereof is permitted. A first spring exerts a compressive force against the valve stem, toward the plug, to bias the valve stem into the locked position. A second spring exerts a compressive force against the plug in order to seat the plug within the valve chamber regardless whether the valve stem is in the locked or the unlocked position.
