1.
In valves ≤DN 50, unscrew the lock nut
(6.2) and stem connector nut (6.1) from
the plug stem.
2.
Unscrew the coupling nut (5.1) from the
bellows housing. Remove nuts (1.1) and
lift off the flange (5.4).
3. Pull out the bellows housing (5.2) and
bellows seal as far as they will go. Place
an open-end wrench SW 10 (≤DN 50)
or SW 13 (≥DN 65) at the side on the
hexagon (X) or at the flattened area of
the plug stem to hold the stem stationary.
Loosen the nut (12) and remove the
wrench.
