Weil McLain 383-700-196 Venturi Valve Assembly ECO/WM97+155

The Weil McLain 383-700-196 Venturi Valve Assembly is used in the ECO and WM97+155 models of boilers where it controls the necessary air to gas mixture to be used in the combustion of HVAC systems. It is installed as part of the burner assembly, and its design is based on a venturi-based design to establish the correct pressure difference to draw and mix fuel with the incoming air prior to ignition. This is a controlled mixing process that assists in the coordinated operation of the burners and stable flame properties.
