The HEINZMANN gas valves for controlling the mixture in gas engines can handle various different gas qualities. We supply gas valves for both mechanical and digital control. The electronically controlled version can regulate the required gas volume particularly precisely and is CAN-compatible for all common protocols. This makes it the ideal choice for integration into an existing AFR control system. By contrast, the mechanical variant is a good solution for all engine sizes between 25 kW and 3 MW where there is no need for precise emissions control.
