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).

english

4.2 Replace swivel plate set

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”).

WARNING!

Risk of injury due to parts being ejected.

When the spindle opening is exposed, the individual parts of the

packing gland will be pressed out at an undened speed when

the pilot air port is pressurised.

▶Before pressurising with pilot air, safeguard the area around

the outlet, (e.g. place spindle on a rm surface).

english

→Using compressed air, press packing gland out of the packing

gland tube.

For control function A and I:

Pressurise pilot air port 1 with compressed air (6...8 bar)

For control function B:

Pressurise pilot air port 2 with compressed air (6...8bar)

→Grease the individual parts of the new packing gland with the

supplied lubricant.

→Place individual parts on the spindle in the specied direction

and sequence.

→Push the packing gland into the packing gland tube.

→Screw in the spindle guide using the socket wrench. Observe

tightening torque (see “Tab. 4”)!
