FAQ

Q: Why 316L instead of 304 stainless steel?
A: 316L contains 2-3% molybdenum which provides significantly better resistance to chloride-induced pitting corrosion, critical for chiller applications where water quality varies and chemical treatment is used.

Q: Is this suitable for seawater-cooled chiller applications?
A: While 316L offers good corrosion resistance, for direct seawater exposure we recommend consulting our engineering team for titanium or super duplex options.

Q: What is your quality inspection process?
A: Each valve plate undergoes dimensional inspection, surface roughness testing, dye penetrant crack detection, and material certification verification before shipment.
