NDL is the only manufacturer of the CRN approved ball valves and check valves for pressures up to 140 bar. Our valves can hold five times their maximum working pressure, netting a tremendous safety margin for any ball valve used in CO2 systems.
The CO2 lineup includes Stainless Steel Ball Valves, with thicker walls than the industry standard and have an all-around stronger stainless steel design to hold higher pressures.

Our C194 Copper Check Valves hold the same attributes as the stainless steel check valves and are a must-have for refrigeration systems.
Sizes and Connections
A wide range of sizes and connection types makes our valves compatible with main pipe types manufactured from copper iron alloys and stainless steel.
Stainless Steel Body
The NDL CO2 valves feature a stainless steel body for stainless steel and copper-alloy connections.
Tested for High Quality
Each valve is helium tested at the factory to guarantee leak-free performance.
Teflon Seals and Seats
Reduce service calls, refrigerant loss, and environmental contamination with our cone-shaped 100% virgin Teflon seals and seats that will not shrink or leak, eliminating seal replacement during changeovers.
Our stem placement is engineered from the bottom up. If there is an accidental over-pressurization in the valve, it will not blow the stem out with resulting loss of the charge.
Our two-year warranty proves confidence. Every valve is tested and serial number stamped. Valves are cleanly packaged in a poly-bag and boxed to prevent contamination in transit to the job sites.
