DANGER!
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 a nalysis applica-
tions, use approved lubricants only.
NOTE!
Damage to valve body or valve seat seal.
To avoid damage, the valve must be in an open position when
the actuator is disassembled.
→
Before re-installation, grease the external thread of the body
connection (e.g. with Klüberpaste UH1 96-402 from Klüber).
→
Position the external thread of the valve body on the internal
thread of the body connection."Figure 6" on page 18.
→
Place on the body connection with a suitable open-end wrench.
D o not use any tools for unscrewing, which could damage
the body connection.
WARNING!
Risk of injury when failing to observe tightening torque value.
Failure to observe the tightening torque value is dangerous due
to the risk of damage to the device.
▶ Observe the tightening torque value.

Holding device
To protect the valve actuator from damage resulting from
forces and vibrations, a holding device is recommended.
This is available as an accessory. See operating instruc-
tions on the website https://country.burkert.com.
Next steps:
• Electrical connection.
The position of the ports can be changed by turning the
actuator through 360°. For a description see chapter
"Rotating the actuator".
