Î If the initial breakaway torque required
to open the valve is too high, the wash-
ers (23) in positionB (between the metal
tubular seal and retainer) press with too
much force against the segmented ball.
In this case, change the position of the
washers (23) from positionB to A (at the
seat in the valve body).
Î If the seat leakage is too high, the wash-
ers (23) on the seat in the valve body
(positionA) are not pressing with suf-
cient force against the segmented ball. In
this case, change the position of the
washers (23) from positionA (at the seat
in the valve body) to positionB (between
the metal tubular seal and retainer).
