Inspecting the state of the valve and possible repair

Check the state of the ball (Item 4): it has to be clean and unscratched. If the cleaning or polishing is not
possible, replace it (see the § on spare parts).

Check the state of the seats (3.1 and 3.2): they must not be deformed, nor scratched, nor worn, or dirty.
Otherwise, replace them with parts from the gasket kit.

Check the state of the packing gland (7.8 and 9): no leak should be found at the stem and the rings
should not be excessively worn. If need be, replace the gaskets.

Check the state of the body gaskets (6.1 and 6.2). Replace them if necessary.

Reassemble the different parts of the valve, following the tightening torques shown in the table below.

Check that the stem manoeuvring is smooth. Perform about ten manoeuvres.
