5.1.1. A plant JSA is acceptable in lieu of the Team JSA as long as all points are covered.

5.2. Verify the valve is aligned to the I.D. of the fitting and the gate clears the bore of the valve.

5.3. Inspect the valve and fitting for foreign materials, proper operation and bore size. Verify the fitting is not back welded.

5.3.1. If the fitting is back welded, contact Technical Support.

5.4. Confirm the Customer has pressure tested the valve and fitting.
