6.7 Installation
♦
The plant components to be protected are to be
cleaned thoroughly prior to installation of the valve.
♦
Solids jeopardise the soft-sealing, high-precision
surfaces of the seat and plug and permanent leaks
could arise. The valve will leak.
♦
The safety valve must be installed so that no
inadmissible mechanical or thermal stresses are
transmitted from the attached pipes to the body.
♦
Changes in length of the pipes due to temperature
are to be allowed for, e.g. through the installation
of expansion joints.
♦
Remove the flange covers.
♦
For KSE/F:
Before installation (vales with set pressures
≤ 0.5
bar), remove metallic transport securing strip and
cap nut for securing the valve during transport.
Screw on attached lead-sealed cap nut
927/1
. See
Section 5.1
.
♦
For KSE-C/F:
Before commissioning, remove transport securing
device. See
Section 5.2
.
♦
Remove the securing wire between the bonnet
513
and the lifting lever
238
.
♦
Position and align the safety valve and any
additional gaskets. Then tighten the pipe screws
with a torque wrench in diametrically opposite
sequence.
For tightening torques, see
Section 1.3
.
6.8 Blocking screw (option)
During the pressure test of the plant the
safety valve cannot discharge through the
blocking screw.
♦
This blocking screw may only be used for this
purpose.
Always remove again immediately
.
♦
Damage to the valve could occur and pressure
protection is then no longer provided.
♦
The lead-sealed cap nut
927/1
is replaced during
the pressure test of the plant by a cap nut
927/1B
with an additional tapped bore
for the blocking
screw
901/4
.
♦
In the
KSE/F 100/150
the lead-sealed hex. screw
901/3
is replaced by a threaded rod
918/1
with a
prevailing torque type hex. nut
929/2
.
The cap nut/blocking screw or the threaded
rod/hex. nut are supplied separately. See also
Fig.
6
.
♦
After the pressure test
remove
the
cap nut
927/1B
with the blocking
screw
901/4
or threaded rod
918/1
with the hex. nut
929/2
again.
♦
Screw in the cap nut
927/1
or the hex. screw
901/3
with the bore for the lead seal again and have
them lead-sealed again. See also
Fig. 6
.

6.9 Gas-tight design
(Option)
An O-ring
400/4
seals the lifting lever
238
.

Section 10.1
6.10 Signal transmitter (Option)
On request, an signal transmitter is available for
remote monitoring.
♦
Glue in stem extension
805
(e.g. Loctite 638) and
secure with a hex. nut
920/4
.
♦
The support, lower part,
542
is screwed on instead
of the cap nut
927/1
.
♦
Insert the O-ring
400/3
.
♦
Mount support, upper part,
541
.
♦
Screw in signal transmitter
859
; after adjustment,
counter with hex. nut.
♦
Secure support, upper part, with setscrew
904/1
.
♦
Design with blocking screw:
Insert the O-ring
400/2
, screw in hex. screw
901/4
and lead-seal. See
Fig. 10.
