NDL CO2 Valves

CO₂ Valves

NDL is the manufacturer of the first CRN-approved* ball valves and check valves for pressures up to 140 bar. The ball 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, stainless steel service valves, stainless steel check valves, C194 copper ball valves, and C194 copper check valves. Their robust design meets and exceeds industry standards for holding maximum working pressure, garnering reliability for transcritical CO₂ refrigeration applications.

NDL offers a wide range of sizes and connection types which makes their valves compatible with main pipe types manufactured from copper iron alloys and stainless steel. Each valve is helium tested at the factory to guarantee leak-free performance and the NDL CO₂ valve features a stainless-steel body for stainless steel and copper-alloy connections. There is a reduction in service calls, refrigerant loss, and environmental contamination with its cone-shaped 100% virgin Teflon seals and seats that will not shrink or leak, eliminating seal replacement during changeovers. The stem placement is engineered from the bottom up, so if there is an accidental over-pressurization in the valve, it will not blow the stem out and lose the charge. Plus, using the virgin Teflon seals ensures no need for seal replacement.

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.
