Patent abstract
A gas valve may include a valve body and a valve member disposed within the valve body. A resilient sealing ring may be disposed within the valve body such that the valve member achieves a closed position when the valve member contacts the resilient sealing ring. In some instances, a gas valve may include both an upper resilient sealing ring and a lower resilient sealing ring. The upper resilient sealing ring and the lower resilient sealing ring may both permit overtravel.
