2. Tack weld valve into position and check for appropriate
alignment.
3. Finish weld following proper weld procedure for material
grade and condition, and the above caution.
4. If weld procedure being used requires post weld heat
treament, the folowing is applicable.
A.) Localized post weld heat treatment limited to the weld and the
heat affected zone does not require disassembly of the valve,
and use of this method does not void the valves pressure test
certifications. However, it is imperative that the body temper-
ature be monitored and controlled as described in note 1.
B.) Post weld heat treatment of the entire body does require dis-
assembly of the valve in order to pervent damage to the valve
internals. Disassembly of the valve voids testing certifications.

service only. Throttling may cause excessive and non-uniform
