Study the instructions carefully. The items refer to the parts list and service kits section. Handle scrap correctly.
5.4 Valve assembly
Reverse order of 5.2 Dismantling the valve.
Lubricate O-ring (21) and lip seal (25) with Klüber Paraliq GTE 703.
Remember to tighten spindle and plug to a torque of 30Nm. (to use two 17mm spanners)
If there are vibrations in the pipeline Alfa Laval recommended using loctite no. 243.
The clamps thread must be lubricated before tightening - max. torque for the clamps is 10-12 Nm.
Note! Do not forget to screw in lower set screw (7) when assembling the valve.
It acts as a stroke stop. Without this screw the valve can be opened so far that the crank comes off.
In some valve sizes the flats on the plug stem may enter into the lip seal, which will then leak.
