WARNING!
Danger if incorrect lubricants used!
Unsuitable lubricant may contaminate the medium. In oxygen applications there is a risk
of an explosion.
•
In specific applications, e.g. oxygen or analysis applications, use appropriately
authorized lubricants only.
Risk of injury from unintentional activation of the system and an uncontrolled
restart!
•
Secure system from unintentional activation.
•
Following assembly, ensure a controlled restart.
WARNING!
Risk of damage from improper installation!
Assembly with unsuitable tools or non-observance of the tightening torque is dangerous
as the device may be damaged.
•
For installation use an open-end wrench, never a pipe wrench.
•
Observe the tightening torque (see below).
Tightening torque: 40 ±3 Nm
Grease pipe thread before re-installing the actuator (e.g. with Klüber paste UH1 96-402 from Klüber)
For control function A: Pressurize control air connection with compressed air (5.5 bar) so that the
disk is lifted off the valve seat and is not damaged when screwed in.
Screw actuator into the valve housing. Observe tightening torque (see above)!
NOTE!
If the position of the control air connection is unfavorable for installation of the
hose, the control air connection can be rotated steplessly through 360° .
