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.
- Heavy-duty Full Port Valves
Built to last with 900 PSIG working pressure on sizes up to 7/8”.
- 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.
- Bottom-Up Stem Installation
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 and lose the charge. Plus, using the virgin Teflon seals ensures no need for seal replacement.
- Two-Piece Cap Nut
No need to remove the cap during installation or service. Loosen the nut, turn 1/4 of the stem cap, and open the valve fully; close by turning 1/4 again. Tighten the nut, and the job is complete.
- Oven-brazed construction
Joined together with a smooth and equal brazing process to prevent pin-hole leaks.
- Quality tested
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 packaging in a poly-bag to prevent contamination and malfunctions.
