A gas valve includes a valve seat, a valve stem, a valve body, and a valve diaphragm. The valve body acts together with the valve seat in such a way that the gas valve is in a closed state when the valve body is pressed against the valve seat and the gas valve is in an opened state when the valve body is lifted up from the valve seat. In a partially opened state, a connection between the valve stem and the valve body allows the valve body to tilt relative to the valve stem. The tilt may help provide more stable contact between the valve body and the valve seat when the gas valve is in the partially opened state. This can reduce wear on the gas valve by reducing, for example, valve body bounce.

Gas valve and gas control device

A method for determining an change in an operating condition of a gas burner appliance. In some instances, a calibration of a gas/air mixture may be performed when the combustion quality of the gas burner appliance diminishes. This may be accomplished by adjusting a throttle position of a throttle valve that throttles the gas to the gas burner appliance. After calibration has been performed, a throttle position of the throttle valve is determined, and based on the throttle position determined after calibration, a change of an operating condition of the gas burner appliance is detectable.
