4 CHANGE SWIVEL PLATE SET
DANGER!
Risk of injury from discharge of pressure and escaping medium.
Working on a device, which is under pressure, is hazardous due to
a sudden discharge of pressure or escaping medium.
▶Before working on the device or system, switch o the pressure.
Vent or empty the lines.
WARNING!
Risk of injury due to using wrong tool.
Performing installation work, using unsuitable tools, is hazardous
due to possible damage to the device.
▶To remove the actuator from the valve body, use an open-end
wrench, never a pipe wrench.
Before replacing the replacement parts, remove the actuator
from the valve body.
4.1 Removing actuator from the valve body
→Clamp valve body in a holding device (only for valves which
have not yet been installed).

4.3 Installing actuator on valve body
WARNING!
Danger from using wrong lubricant.
Unsuitable lubricant may contaminate the medium. There is a risk
of explosion in oxygen applications!
▶For specic applications, e.g. oxygen or analysis applications,
use approved lubricants only.
→Check seal and replace if required.
→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 removing the actuator, the valve must be in the open
position.
▶For control functions A (SFA) and I (SFI) pressurise the pilot air
port 1with compressed air (5 bar): Valve opens.
→Screw actuator onto valve body. Observe tightening torque (see
“Tab. 2”).
