Gas valve , comprising a valve seat , a valve stem , a valve body , wherein the valve stem is attached with a first end of the same to a first side of valve body , wherein the valve body acts together with the valve seat in such a way that the gas valve is closed when the valve body is pressed against the valve seat and that the gas valve is opened when the valve body is lifted up from the valve seat , a valve diaphragm plate mounted to a second end of the valve stem , a valve diaphragm mounted to the valve diaphragm plate , wherein a first pressure is present on a first side of the valve diaphragm and a second pressure is present on a second side of the valve diaphragm , wherein the pressure difference between said first pressure and said second pressure provides a pressure dependent force acting on the valve stem , a valve spring element providing a spring dependent force acting on the valve stem , wherein the gas valve opens and closes as a function of the pressure dependent force and spring dependent force both acting on the valve stem , wherein the valve spring element is acting directly on a second side of the valve body , wherein an end of the valve spring element is supported against the second side of the valve body , a longitudinal axis of the valve spring element runs coaxial to a longitudinal valve stem axis , characterized in that the first end of the valve stem and/or the first side of the valve body provides a tilt element allowing the valve body to tilt around a defined tilt axis relative to the valve stem , wherein the tilt axis for the valve body runs perpendicular and offset to a longitudinal axis of the valve seat , the second end of the valve stem and/or the valve diaphragm plate provides an anti-rotation element preventing the valve stem to rotate around the longitudinal valve stem axis . wherein the valve stem is attached with a first end of the same to a first side of valve body , wherein the valve body acts together with the valve seat in such a way that the gas valve is closed when the valve body is pressed against the valve seat and that the gas valve is opened when the valve body is lifted up from the valve seat , wherein a first pressure is present on a first side of the valve diaphragm and a second pressure is present on a second side of the valve diaphragm , wherein the pressure difference between said first pressure and said second pressure provides a pressure dependent force acting on the valve stem , wherein the gas valve opens and closes as a function of the pressure dependent force and spring dependent force both acting on the valve stem , wherein the valve spring element is acting directly on a second side of the valve body , wherein an end of the valve spring element is supported against the second side of the valve body , a longitudinal axis of the valve spring element runs coaxial to a longitudinal valve stem axis , characterized in that the first end of the valve stem and/or the first side of the valve body provides a tilt element allowing the valve body to tilt around a defined tilt axis relative to the valve stem , wherein the tilt axis for the valve body runs perpendicular and offset to a longitudinal axis of the valve seat , the second end of the valve stem and/or the valve diaphragm plate provides an anti-rotation element preventing the valve stem to rotate around the longitudinal valve stem axis . <EOS>
