Always follow standard safety procedures when working on a valve.
Prior to installation, inspect the valve thoroughly. Look for any
loose air fitting connections, loose fasteners, bent air supply line,
or any other visual signs of obvious damage. Remove the protective
covers from the valve end connections. Using a suitable solvent, wipe
the valve end connections to insure that they are free from any debris
or visible foreign matter. Recommended solvents are clean or re-distilled
acetone, or alcohol. do not use chloride or fluoride bearing solvents.
Flush the pipeline and clean before installing the valve. Debris allowed
to remain in the pipeline (such as weld spatters, welding rods, bricks,
tools, etc.) can damage the valve.
Ensure that the pipe openings are well suited to the size and shape
of the valve. Do not attempt to pull any piping to the valve by over-tightening
the valve end connection/piping studs during installation.
Power ball valves will only seal against pressure in one direction.
Verify that the valve is installed in the correct sealing orientation.
