Description
The Triangle Tube PARKIT20 Venturi Valve Kit PA110 controls the air-gas mixture supplied to the burner in compatible high-efficiency boiler assemblies. As intake air moves through the Venturis narrow throat, its velocity creates a localized pressure drop that draws fuel gas into the airstream. Installed within the air intake and fuel manifold assembly of heating units in HVAC systems, the valve maintains the relationship between incoming air and fuel as firing conditions change. This metering action adjusts the gas entering the combustion airstream according to airflow, maintaining the air-to-fuel ratio across different firing rates and supporting consistent combustion throughout the heating cycle.
