General installation
Step 1
-
Always read the technical data thoroughly (see 7.1 Technical data).
-
Always release compressed air after use.
-
Never touch the clip assembly or the actuator piston rod if the actuator is supplied with compressed air
(see the warning label)
CAUTION!
-
Fit the supplied warning label on the valve so that it is clearly visible.
-
Alfa Laval cannot be held responsible for incorrect installation
NOTE!
-
The leakage outlet must be turned downwards!
Step 2
Avoid stresses to the valve as this can result in deformation of
the sealing area and misfunction of the valve (leakage or faulty
indication).
Pay special attention to:
-
Vibrations
-
Thermal expansion of the tubes (especially at long tube lengths)
-
Excessive welding
-
Overloading of the pipelines
NOTE!
Please follow Alfa Laval installation guidelines (literature code
ESE00040).
