5.3.3 Mounting the valve with
threaded connection
Fig. 5-4 Mounting the valve with threaded con-
nection in the pipeline
1.
Before applying additional sealing mate-
rials, test whether the pipeline can easily
be screwed into the valve body.
2.
Apply suitable sealing material to the
pipeline ends. By using PTFE-ribbon or
hemp sealings observe the screw direc-
tion. Do not use sealing material that is
not suitable for your intended purpose.
3.
Screw the pipelines into the threaded
ends of the ball valve. Do not use the
complete valve as a lever!
4.
Attention! Before you pressurize the
pipeline, the sealing material must be
hardened. Information on the harden-
ing time is available from the respective
manufacturer.
5.
Check all connections for leaks.
5.4 Mounting the rotary actuator
For information on
mounting
the actuator,
refer to the manufacturer documentation
supplied with the actuator (from bar
GmbH for PKI and from Valpes for EKI).
5.5 Pressure test of the pipe
section
The following must be observed when mak-
ing the pressure test of a pipe section with
installed valves:
Carefully rinse newly installed piping sys-
tems to flush out any foreign objects.
Valve opened:
•
The test pressure must not exceed the
value of 1.5 x PN as marked on the
housing.
Valve closed:
•
The test pressure must not exceed the
value of 1.1 x PN as marked on the
housing.
