Risk of property damage due to excessive heat!
In case of short welding ends, excessive heat may cause damage to soft seal.
If possible, put a wet towel over the Argus Ball Valve.
Monitor the temperature of the valve body in the seat area by using the temperature-
sensing strips during welding.
The maximum permitted temperature is: 100 °C
(position of the temperature-sensing strips)
Continuously monitor the measuring strip during welding.
In case of a reaction (color change), interrupt the welding.
Let the valve body cool down.
6.
Weld the Argus Ball Valve to the second welding end.
Ensure correct placement and correct alignment of the Argus Ball Valve with the piping
connection.
Installation of the Argus Ball Valve is now complete.

Installing/Aligning the Actuator
Actuators are usually installed above the Argus Ball Valve if the stem of the ball valve is in a
vertical position. Other types of installation are possible depending on assessment of the
specific application conditions.
In case of heavy and/or asymmetrical actuators or with units which are not installed
vertically, critical bending or torsional forces can occur, especially on extended
stems, for example, those equipped with a stuffing box. Have on-site support
provided for installing the actuator.
In case of critical vibrations or impacts during operation, it is also useful to
additionally support the actuator or provide shock absorption.
