Refrigeration Ball Valves
Engineered for refrigeration, commercial HVAC, VRV, VRF, multi-mini split, and sub-critical applications, NDL full port refrigeration and A/C ball valves are the best in their class.
Design and Features
- Heavy-duty Full Port Valves
Our valves are built to last with a 900 PSIG working pressure on sizes up to and including 7/8”. Therefore, you can trust their durability and performance in demanding conditions. - Teflon Seals and Seats
Reduce service calls, refrigerant loss, and environmental contamination with our cone-shaped 100% virgin Teflon seals and seats. As a result, these seals will not shrink or leak, eliminating the need for seal replacement during changeovers. Furthermore, their reliable design ensures long-term efficiency in your system. - Bottom-Up Stem Installation
Our 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. - Two-Piece Cap Nut
There is no need to remove the cap during installation or service. Instead, loosen the nut, turn the stem cap 1/4, and open the valve fully. Similarly, close the valve by turning 1/4 again, tighten the nut, and the job is complete. As a result, the process is quick and straightforward, saving you time and effort. - Oven-brazed construction
The components are joined together with a smooth and equal brazing process. Therefore, this method prevents pin-hole leaks, ensuring reliable operation for the long term. - Quality tested
Our refrigeration ball valves are tested with 95% nitrogen and 5% hydrogen solution at 450 PSIG to detect and correct any leaks before leaving the factory. - Backed by an unparalleled two-year warranty
Our warranty proves our product confidence, along with proudly stamping every valve with a serial number and cleanly packaged in a poly-bag to prevent contamination and malfunctions.
