Installation
The type of materials carried in the pipeline and the location of the valve determine the correct
installation procedure.
Liquids without Suspended Solids and Clean Gases
1. Before installation, remove foreign material such as weld spatter, oil, grease, and dirt from the
pipeline.
2. Prepare pipe ends and install valves in accordance with the pipe manufacture’s instructions for
the joint used.
Note:
See Figure 1 for proper valve orientation.
Do not deflect the pipe-valve joint. Minimize bending stresses in the valve end
connection with pipe loading.
3. Ensure the valve and flanges are concentric to ensure proper flange sealing.
4. Tighten the flange bolts or studs in a crisscross pattern.
