Removing the bonnet of equipment with
pneumatic actuator
If the equipment is fitted with a pneumatic
actuator, the bonnet (here called yoke) is
an elemental part of the actuator.
In this type of equipment the bonnet is
called "yoke".
In order to distinguish the yoke more
clearly from the standard bonnet, the
following drawing shows the actuator. The
actuator must be removed before the
bonnet can be dismounted.
 Do not dismount the yoke before all
actuator parts including the coupling
have been removed.

For this purpose proceed as described
in section „Removing actuator parts" on
page 27 beschrieben.

Unscrew the screw-in adapter (38) from the
stem (1.).

Unscrew the groove nut (36) (2.).

Lift off the yoke (2) together with the actuator
(3.).

Take off the distance ring (37).
