♦ Screw on lifting cap 535 and tighten.
♦ Insert lifting lever 238 .
♦ Mount locking plate 539 .
♦ Have valve lead-sealed.
♦ The data specified in the test certificates are to be
observed.
9.5 Important notes on disman-
tling / installation
First relieve plug 204 and lift it off the seat.
♦ The seat and plug could otherwise be destroyed.
Read the precise instructions in Section 9.6 , 9.7
and 9.8 ..
♦ Then undo the screws between the body 100 and
the inlet nozzle 122 or between the bonnet 513
and body 100 .
♦ Always replace the seat and plug pairwise and
always rework them completely .
♦ Reworking of the seat and plug requires special-
ised knowledge of the material as well as special
lapping wheels.
♦ It is therefore recommended to have this work
carried out by the manufacturer.
♦ After dismantling, check all parts for wear and
damage.
♦ Observe sectional drawings in Section 10 .
9.6 Replacement of components
9.6.1 Dismantling of the plug
♦ Undo locking plate 539 , dismantle lifting lever 238
and unscrew the lifting cap 535 .
♦ Mark the position of the stem nut 534 .
♦ Unscrew the prevailing torque type hexagon nut
929/1 and stem nut 534 off the stem 802 .
♦ When undoing or tightening the prevailing torque
type hexagon nut 929/1 , carefully hold the spindle
tight with pliers to prevent it from turning.
Do not turn the entire stem 802! There
is a risk that the insert sleeve 308 will be
screwed out of the bellows 206 and the
folds or the spring-type pin 939/1 will be
damaged!
♦ Mount a suitable distance sleeve (not included in
the scope of delivery) over the stem 802 .
♦ Screw the stem nut 534 against the distance
sleeve. The plug 204 is lifted off the seat 205 and
the closing force becomes ineffective.
♦ Loosen the bolts 901/1 , 936/1 , 936/2 and 920/2 (in
the case of KSE/F and KSE-C/F 100/150 902/2 ,
934/1 , 936/1 and 920/2 ) from body 100 and spring
bonnet 513 and lift the bonnet with internals com-
pletely off.
♦ Grip the bellows 206 in the reinforced section just
above the lifting aid 237 . Unscrew the lifting aid off
the bellows and remove the plug 204 .
9.6.2 Dismantling of the seat
♦ Remove spring bonnet 513 from the body 100 .
♦ See Section 9.6.1 .
♦ Dismantle inlet nozzle 122 from the body 100 and
remove the seat 205 .
9.6.3 Installation of the seat
♦ Insert the new or reworked seat 205 at the bottom
into the corresponding centring of the body 100 .
♦ Then insert the inlet nozzle 122 into the centring of
the body 100 .
The components must be smooth running, i.e. can
be centred without any constraining forces.
If necessary, the inlet nozzle is to be turned
through 90°.
♦ First tighten the attachment nuts 920/1 hand-tight
and then with a torque wrench evenly and in
diametrically opposite sequence.
It is imperative to observe the prescribed
torques for the connection body / inlet
nozzle! See
Section 9.3 .
9.6.4 Installation of the plug
♦ All parts are to be thoroughly cleaned before
assembly.
♦ Centre the new or reworked plug 204 in the lifting
aid 237 and screw completely onto the thread of
the bellows hand-tight. Hold the bellows 206 at
the reinforced section.
♦ Undo the hex. socket screws 914/1 . Centre the
spring bonnet 513 with internals on the body 100 .
Ensure that there is metallic contact between the
body and the spring bonnet. Then tighten the
screws
901/1 , 936/1 , 936/2 and 920/2 (on KSE/F
and KSE-C/F 100/150 902/2 , 934/1 , 936/1 and
920/2 ).
