a. Valves, having both of the following:
1. A nominal size greater than DN 10 or NPS 3/8, and
2. All surfaces that come in direct contact with the chemical(s) are made from the materials of construction in Technical Note 1 of this entry;
b. Valves, not already identified in paragraph 6.a., having all of the following:
1. A nominal size equal to or greater than DN 25 or NPS 1 and equal to or less than DN 100 or NPS 4
2. Casings (valve bodies) or preformed casing liners,
3. A closure element designed to be interchangeable, and
4. All surfaces of the casing (valve body) or preformed case liner that come in direct contact with the chemical(s) are made from the materials of construction in Technical Note 1 of this entry;
c. Components, as follows:
1. Casings (valve bodies) designed for valves in paragraphs 6.a.or 6.b., in which all surfaces that come in direct contact with the chemical(s) are made from the materials of construction in Technical Note 1 of this entry;
2. Preformed casing liners designed for valves in paragraphs 6.a.or 6.b., in which all surfaces that come in direct contact with the chemical(s) are made from the materials of construction in Technical Note 1 of this entry.
Technical Note 1. Materials of construction for valves include any of the following:
a. nickel or alloys with more than 40% nickel by weight;
b. alloys with more than 25% nickel and 20% chromium by weight;
c. fluoropolymers (polymeric or elastomeric materials with more than 35% fluorine by weight);
d. glass or glass-lined (including vitrified or enamelled coating);
e. tantalum or tantalum alloys;
f. titanium or titanium alloys;
g. zirconium or zirconium alloys;
h. niobium (columbium) or niobium alloys; or (i) ceramic materials as follows:
1. silicon carbide with a purity of 80% or more by weight;
2. aluminum oxide (alumina) with a purity of 99.9% or more by weight;
3. zirconium oxide (zirconia).
Technical Note 2. The 'nominal size' is defined as the smaller of the inlet and outlet port diameters.
Technical Note 3: Nominal sizes (DN) of valves are in accordance with ISO6708:1995. Nominal Pipe Sizes (NPS) are in accordance with ASME B36.10 or B36.19, or national equivalents.
