Description
The McCann Carbonator Single Check Valve is a critical safety component for commercial soda fountain systems. Featuring a 1/4″ Male Flare (MFL) connection, this valve is designed to prevent the reverse flow of carbonated water into the water supply line, protecting against contamination and copper leaching. Precision-engineered to OEM specifications, it ensures a 100% one-way path for high-pressure carbonated liquids. A essential replacement part for maintaining the safety and compliance of industrial carbonator units.
Technician’s Note: Install this valve on the water inlet of the carbonator. The 1/4″ MFL connection allows for a tool-free, gas-tight seal using a standard swivel nut and nylon flare washer. Periodically test the valve for proper shut-off; a failing check valve is the leading cause of “carbonator hunting” and water supply contamination. This is a genuine Multiplex/McCann replacement part.
