3.5 Valve assembly
The current version of the BR 01b valve manufactured after 2006
has design differences in the area of the stem sealing in compari-
son to the version manufactured before 2006 so that they cannot
be documented in one construction manual.
− Chapter 3.5.1 describes the assembly of the current valve
manufactured after 2006.
− Chapter 3.5.2 describes the assembly of the valve from
DN 80 / NPS3 manufactured before 2006.
Preparation of the assembly
To assemble the valve, all parts must be prepared, e. g. the parts
are carefully cleaned and placed on a soft mat (rubber mat or
other). Keep in mind that plastic parts are almost always very
soft and very delicate, and in particular the sealing surfaces may
not be damaged.
Damage to the valve due to cold welding of the screws in the
body!
PFEIFFER recommends a heavy-duty grease paste (e.g. Gleitmo
805, manufacturer Fuchs) to prevent the cold-welding of the
screws in the bodies.
Ö
Do not use this product for valves with use of oxygen. A suit-
able lubricant must be selected for grease-free valves, espe-
cially for use with oxygen.
Info
NOTE
The positions and arrangements of the individual parts shown in
the drawings must be observed during assembly.
3.5.1 Valve assembly manufactured after
2006
3.5.1.1 Valve body assembly
Ö
Clamp the valve body (1) with the fl ange in a vice so that the
bearing area of the seat is easily reached.
Ö
Screw in the PTFE seat (3) using a suitable special tool into
the thread of the body (1). For the tightening values of the
seat, see Table 15-2 in Chapter “15.1.1 Tightening torques”.
Damage to the valve due to improper assembly
The thread on the seat and in the valve are delicate and can be
damaged
Ö
Do not twist the seat when screwing in and do not damage
the thread.
Ö
Rework the seat inner diameter to size.
3.5.1.2 Assembly of the stem
Ö
Push the retainer ring (22) from the short thread side into the
groove of the stem (12).
Damage to the parts of the stem sealing in contact with media
due to unsuitable grease.
Ö
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).
Ö
Grease the stem (12) on the bottom thread.
Ö
Screw the bellows (5) with a preassembled washer and bush-
ing onto the greased thread of the stem (12).
Due to the sliding property of the PTFE, we recommend using em-
ery cloth to prevent the bellows from sliding when screwing it on-
to the stem.
To make it easy to push on the plug stem, make a small notch in
the bellows to let air escape.
