The gas mixing valve (electromagnetic fuel gas supply valve) is a high-speed gas inlet valve with an electric drive for supplying fuel to the fuel collector. The valve consists of electrical and mechanical parts. The mechanical part of the valve requires regular maintenance for maximum performance. The mechanical part of AGV gas mixing valves is designed as a replacement and ready-made solution for gas mixers used in most GPA (Cat, Waukesha, Wartsila, etc.), easily fits into the existing engine design without any mechanical modifications.
