Abstract
A gas valve, in particular a metering valve for a gaseous medium, having a valve washer () which is arranged in the gas valve so as to be able to move with respect to a longitudinal axis (), and having a valve plate () with a valve seat () formed thereon, wherein the valve washer () interacts with the valve seat () for opening and closing the gas valve, and having a first circumferential sealing edge () between the valve seat () and the valve washer (). The valve washer () has a central opening () through which the gaseous medium passes, wherein the first circumferential sealing edge () surrounds the central opening () and wherein, in the central opening (), there is formed a first pressure face () upon which the gaseous medium acts in the closing direction. Furthermore, there is arranged on the valve washer () a second pressure face () which is formed radially outside the first circumferential sealing edge () and on which the gaseous medium also acts. The first pressure face () and the second pressure face () are connected via a connection passage () formed in the valve plate ().
