These check valves are designed to hold five times their maximum working pressure, providing a tremendous safety margin for any check valve used in CO₂ systems.
01
The NDL C194 copper check valves range from ¼” to 1-5/8” and are compatible with main pipe types manufactured from copper-iron alloys. Each valve is helium tested at the factory to guarantee leak-free performance and the NDL CO2 check valve features a stainless-steel body with copper-iron alloy connections. Their check valves feature a compact, streamlined design that minimized flow resistance, ensuring optimal performance, energy efficiency, and easy installation.
NDL offers an unparalleled two-year warranty, which proves their confidence in the product. Every valve is tested, and the serial number is stamped while being cleanly packaged in a poly bag and boxed to prevent contamination in transit to job sites.
