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 the details in Fig. 5.
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, in the case of the
KSE/F 100/150, the hex. screw 901/4 with the bore
for the lead seal again and have them lead-sealed
again. See also Fig. 6.
