Maintenance, cleaning
Install actuator (with control unit) on the valve body
→
Replace the seal if necessary.
WARNING!
Danger due to incorrect lubricants.
Unsuitable lubricant may contaminate the medium. There is a
risk of explosion in oxygen applications.
▶
For specific applications, e.g. oxygen or analysis applica
-
tions, use approved lubricants only.
→
Before re-installation, grease nipple thread of the actuator
(e.g. using Klüberpaste UH1 96-402 from Klüber).
NOTE!
Damage to the valve seat seal or seat contour.
▶
When installing the actuator, the valve must be in the open
