♦ This must be raised further until the distance
between the upper edge of the insert sleeve and
the edge of the stem guide is approx. 5 mm.
♦ In order to raise the spindle 802 into this position,
the adjusting screw 538 is now pre-tensioned
approx. 25 mm (turned into the bonnet). Then
mount a distance sleeve approx. 35 mm long (or
hex. nuts with U-washer, see
Fig. 18 ) onto the now
free spindle end.
♦ Grease the end surfaces of the spacer sleeve well
so that these surfaces cannot "seize".
♦ A hex. nut is screwed onto the spindle end and
countered with another hex. nut. See Fig. 18.
♦ Undo adjusting screw 538 (turn out of the spring
bonnet 513 ) until the distance between the upper
edge of the insert sleeve and the edge of the stem
guide is approx. 5 mm. See
Fig. 24.
♦ When undoing the adjusting screw 538 , hold the
spindle 802 with a wrench on the counter nut to
prevent it from turning so that the bellows 206 or
the spring-type pin 939/1 are not damaged.

♦ Undo the hex. nuts 920/1 (on the flange of the
spring bonnet 513 ) and lift off the entire upper
section.
♦ Install pressure ring 124 in the thrust flange 117
(observe Section 8.6.5 ) and screw bellows 206
with plug 204 and lifting aid 237 onto the spindle
802 . See Fig. 25.

♦ Assemble the entire upper section with the body
100 . Tighten the hex. nuts 920/2 and hex. socket
screws 914/1 for the pressure ring 124 .
Lowering the bellows onto the seat
♦ For this purpose screw the adjusting screw 538
into the spring bonnet 513 until the spacer can be
freely moved.
When tightening the adjusting screw 538 ,
hold the spindle 802 with a wrench on the
counter nut to prevent it from turning so
that the bellows
206 or the spring-type pin
939/1 are not damaged. See Fig. 26.

♦ Undo the counter nut and remove the spacer.
♦ Now the valve can be set to the specified set
pressure.
♦ Secure the spindle nut 534 and prevailing torque
type hexagon nut 929/1 on the end of the spindle
and counter against each other. Set the adjusting
screw
538 accordingly.
When screwing the prevailing torque type
hexagon nut
929/1 on or off the spindle 802
or when setting the adjusting screw 538 , hold
the spindle with a wrench on the counter nut
to prevent it from turning so that the bellows
206 or the spring-type pin 939/1 are not
damaged. See Fig. 26.
