Question 4

What is DNV GL type approval and is it mandatory for all ship valves?

Accepted Answer

DNV GL (now DNV) type approval is a certification process where a classification society tests and approves a product design for use on vessels under their class rules. Not all ship valves require type approval — it is mandatory for safety-critical systems: sea valves, sea chests, and valves in essential services (fire, bilge, ballast, fuel oil) per IACS Unified Requirement L5. Internal service valves (fresh water piping, sanitary) may use standard industrial valves. Lloyd's Register, ABS, Bureau Veritas, and ClassNK have equivalent type approval processes.

Question 5

Why is gunmetal (CC480K) specified for sea chest valves instead of bronze or brass?

Accepted Answer

Standard naval brass (60Cu-40Zn) dezincifies in seawater — the zinc leaches out, leaving a porous copper sponge with no structural strength. Gunmetal (CC480K: 85Cu-5Sn-5Zn-5Pb) has only 5% zinc and high tin content, making it highly resistant to dezincification. Ni-Al-Bronze (CA104: 9%Al, 4%Ni, 4%Fe, balance Cu) is even more corrosion-resistant and is the preferred material for sea chest boxes and kingstones. SS316 is not suitable for submerged seawater service due to crevice corrosion risk; Super Duplex 2507 is the stainless option if required.
