8.3. Installation

If used in an aggressive environment, we recommend con-
veying all free pneumatic connections into a neutral atmo-
sphere with the aid of a pneumatic hose.
WARNING!
Risk of injury from improper installation!
Non-observance of the tightening torque is dangerous as the
device may be damaged.
• Observe tightening torque during installation (see „Tab. 7: Tight-
ening torques for diaphragms").
8.3.1. D evices with welded housing
NOTE!
To prevent damage!
Before welding the housing (only device with welded housing),
the actuator and the diaphragm must be removed.
Remove actuator and diaphragm from the housing:
Procedure for control function A
→
Pressurize lower control air connection with compressed air
(value as indicated on the rating plate) (see Fig. 17).
This is required to detach the diaphragm without damage from
the housing.
→
Loosen fastening screws crosswise and remove actuator
together with diaphragm from the housing.
→
Weld housing into the pipeline.

Installation
Procedure for control functions B and I
→
Loosen fastening screws crosswise and remove actuator
together with diaphragm from the housing.
→
Weld housing into the pipeline.
Mount actuator and diaphragm on the housing:
→
After welding in the housing, smooth the housing surface by
grinding if required.
→
Carefully clean the housing.
Procedure for control function A
→
Pressurize lower control air connection with compressed air
(value as indicated on the rating plate) (see Fig. 17).
→
Place actuator on the housing.
→
Lightly cross-tighten the housing screws until the diaphragm is
between the housing and actuator.
Do not tighten the screws yet.
→
Actuate the diaphragm valve twice to position the diaphragm
correctly.
→
Without applying pressure, tighten the housing screws to the
permitted tightening torque (see Tab. 7).
→
Pressurize lower control air connection with compressed air (value
as indicated on the rating plate).
→
Check the tightening torque of the screws again.
Procedure for actuator with control functions B and I:
→
Place actuator on the housing.
