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 .

Legend see 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.
