Hi,
Could you please suggest which 2" NPTF check valve is suitable for compressed air system? Swing check valve or ball valve? Please advice.

Thanks,
BN

How is the air line running? Vertical, horizontal, angled down to drain water?
Instrument air or service air?
What is expected max flow, normal flow (often zero in some runs used mainly during outages!), and service life?
DO you have a dryer in the line upstream?
What is the penalty if it fails open? If it fails shut?
Life critical application? Mission critical?
