NOTES:
(a) For Cryogenic Valves, -20°F ratings extend to -325°F
(b) P-T Ratings - ASME B16.24
(c) Solder Joint Valve Ratings may be limite by the solder composition. See MSS SP-80 Paragraph 2.4 and Annex A for more information
(d) Some codes (i.e., -ASME BPVC, Section 1) limit the rating temperatures of the indicated material to 406°F
(e) Alternate Ratings for valve sizes 1/8-2 having threaded ends and metal to metal union body-bonnet joints
