3.5.2.2 Assembling the stem unit
− When assembling the stem, bellows, plug and all other parts
of the stem sealing in contact with media, only use water-free
grease (e.g. halocarbon grease).
Ö
The single-piece stem (16) is greased at the lower thread.
Ö
Screw the bellows (15) with a preassembled washer and
bushing onto the greased thread of the stem (16).
Due to the sliding property of the PTFE, we recommend using an
emery cloth to prevent the bellows from sliding when screwing it
onto the stem.
To make it easy to push on the plug stem, a small notch is made
in the bellows to let air escape.
Ö
Push the plug (13) onto the bellows (15).
Ö
Secure the connection between the plug and bellows with a
PTFE cord (14) inserted as far as possible.
3.5.2.3 Assembling the bonnet fl ange
− When assembling the bonnet fl ange and all other parts in
contact with media, only use water-free grease (e.g. halocar-
bon grease).
Ö
Place the bonnet fl ange (2) on a clean surface at working
height so that the stem guide is easy to reach.
Ö
Insert the distance bushing and V-rings and lock ring of the
V-ring packing (33). For the arrangement of the packing
rings, see Figure 3-3.
Ö
Insert the set of spring washers (34) into the provided hole.
