Replace the control cone set:
→
Knock out dowel pin with a suitable pin punch.
Pin punch ø 4 mm, for spindle diameter 10 mm (see “Tab. 1”).
Pin punch ø 5 mm, for spindle diameter 14 mm (see “Tab. 1”).
Pin punch ø 6 mm, for spindle diameter 22 mm (see “Tab. 1”).

Attach new control cone to the spindle.
→
Align bores of the control cone and spindle.
→
Support control cone on the cylindrical part with the aid of a prism
or something similar.
→
Put on dowel pin and carefully knock in with a hammer.

Install the actuator (with control unit) on the valve body:
→
Check the graphite seal and if required, replace it.
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.
→
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.
→
Control function A:
Without unit control: pressurize the pilot air port 1 with com-
pressed air (5 bar): valve opens.
With unit control: open the valve according to the operating
instructions for the control unit.
→
Screw actuator into the valve body. Observe tightening torque
(see “Tab. 2”).

Risk of injury if the wrong tools are used!
It is dangerous to use unsuitable tools for installation work as the
device may be damaged.
• To remove the actuator from the valve body, use an open-end
wrench, never a pipe wrench.
DAnGer!
Risk of injury from discharge of medium and pressure!
It is dangerous to remove a device which is under pressure due to
the sudden release of pressure or discharge of medium.
• Before removing a device, switch off the pressure and vent the lines.
Before the packing gland can be replaced, the actuator
must be removed from the valve body and the control cone
removed.
The seal set for the packing gland contains:
