Overview
When moving the flanged rupture/relief valve
assembly, keep it in a horizontal position and utilize flat
work surfaces capable of supporting the weight of the
completed valve assembly (approximately 28 lb [12.7
kg] for the 3 in. [76.2 mm] valve assembly, 67 lb [30.4
kg] for the 4 in. [101.6 mm] valve with spool piece, and
40 lb [18.1 kg] for the 4 in. [101.6 mm] valve assembly
[
without
spool piece]).
