Installation and connection
5 Installation and connection
5.1 Preparing for installation
5.1.1 Check operating conditions
1. Ensure the design of the fi tting is consistent with the pur-
pose intended:
–
Materials used ( → nameplate).
– Medium ( → order and design data).
2. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(
→ resistance lists).
– Media temperature ( → data sheet).
– Operating pressure ( → data sheet).
3. Consult with the manufacturer regarding any other use of
the device.
5.2 Planning pipelines
5.2.1 Designing pipelines
WARNING
Risk of poisoning and environmental damage from
medium.
Leaks due to impermissible pipework forces.
Ensure that the fi tting is not subject to any pulling or thrust-
ing forces or bending moments.
1. Plan pipes safely:
– No pulling or thrusting forces
– No bending moments
– Adjust for changes in length due to temperature
changes (compensators, expansion shanks)
– Optional fl ow direction
– Optional installation position
2. Dimensions ( → data sheet).
5.3 Installing fi tting in pipe
WARNING
Risk of poisoning and environmental damage from
medium.
Leak due to faulty installation.
Installation work on the pipes should only be performed
by technicians who have been specially trained for the
pipework in question.
NOTE
Material damage due to contamination of the fi tting!
Make sure no contamination reaches the fi tting.
Flush the pipe with a neutral medium.
The fi tting is installed according to the connection type of
the pipes.
5.3.1 Connection with solvent welding/butt-weld
spigot ends
Do not connect the ASV valve body in the version “ fi xed
connector” by means of butt-welding.
This applies to the heating element as well as infrared butt-
welding procedures.
1. Prepare pipe ends according to connection type.
2. Adhesively apply or weld
fi tting with solvent welding/butt-
weld socket ends ( → manufacturer speci fi cations).
5.3.2 Connection with fl ange
1. Prepare pipe ends according to connection type.
2. Radially push the
fi tting and fl at seal between the fl ange
ends.
3. Bolt fi tting and fl ange with fl ange screws, nuts and wash-
ers.
While
doing so, observe tightening torques:
( → 9.2 Tightening torques, Page 13).
5.3.3 Connection with union nut and insert
1. Prepare pipe ends according to connection type.
2. Unscrew union nuts and slide over free pipe ends.
– Check mounting direction.
3. Connect inserts with pipe ends.
4. Position
fi tting between the pipe ends.
5. Hand-tighten the union nut.
