Abstract
A gas valve has a valve seating surface and flexible valve member to insure that the gas flow is terminated when the valve closes. The valve seating surface has a flat portion around an opening and a raised portion around the peripheral opening. A cooperating flexible valve member has a flat portion and a raised portion around its periphery. When the flexible valve member moves against the seating surface, the raised portion of the flexible valve member engages the flat portion of the seating surface and the raised portion of the seating surface engages the flat portion of the valve member to form two concentric series connected seals to insure that gas flow through the valve is terminated.
