INSTALLING THE ACTUATOR

WARNING!
Danger if incorrect lubricants used!
Unsuitable lubricant may contaminate the medium. In oxygen appli-
cations there is a risk of an explosion!
▶ In specific applications, e.g. oxygen or analysis applications, use
appropriately authorised lubricants only.
→
Check the graphite seal and if required, replace it.
→
Grease nipple thread before re-installing the actuator (e.g. with
Klüber paste UH1 96-402 from Klüber).
NOTE!
Damage to the seat seal or the seat contour!
▶ When installing the actuator, ensure that the valve is in open
position.
Type 2300:
→
Control function A (CFA) and I (CFI)
Without unit control: pressurize the pilot air port
1 with compressed air (5 bar): valve opens.
(For CFB the valve is already open).
With unit control: open the valve according to
the operating instructions for the control unit.
