The Multiplex Double Check Valve is a critical safety component for commercial soda fountain systems. Featuring 3/8" Male Flare (MFL) connections, this valve is designed to prevent the reverse flow of carbonated water into the potable water supply, protecting against contamination and "copper leaching" in plumbing lines. The "double" check design provides a redundant level of protection for industrial carbonator pumps, ensuring your facility remains compliant with local health and safety codes.
Technician's Note: Install this valve inline between the water source and the carbonator pump inlet. Ensure the flow arrow on the valve body points toward the carbonator. The 3/8" MFL connections allow for a tool-free, gas-tight seal using standard swivel nuts and nylon flare washers. Periodically test the valve to ensures the internal seals are functioning correctly.
