7.3 installation
If used in a corrosive environment, we recommend running
a pneumatic hose from all free pneumatic connections to a
neutral atmosphere.
Warning!
risk of injury from incorrect installation.
Non-observance of the specified tightening torque is hazardous
as the device may be damaged.
▶ Observe tightening torque during installation (see "Tab. 2: Tight-
ening torques for diaphragms").
7.3.1 devices with welded or bonded body
note!
to avoid damage!
Before welding or bonding the body, the actuator and dia-
phragm must be removed.
remove actuator and diaphragm from the body:
procedure for control function a
→
Pressurize the lower control air connection with compressed air
(value on type label) (see "Fig. 7: Control air connection"). This
is required so that the diaphragm detaches from the body and is
not damaged.
→
Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→
Weld or glue body into the pipeline.
procedure for control functions b and i
→
Loosen fastening screws in diagonal pairs and remove actuator
together with diaphragm from the body.
→
Weld or glue body into the pipeline.

Assembly
mount actuator and diaphragm on the body:
→
After welding or bonding the body, smooth the body surface by
grinding if required.
→
Carefully clean the body.
procedure for control function a
→
Pressurize the lower control air connection with compressed air
(value on type label) (see "Fig. 7: Control air connection").
→
Place actuator on the body.
→
Gently tighten the body screws in diagonal pairs until the dia-
phragm lies between the body and actuator.
do not fully tighten screws yet.
→
Actuate the diaphragm valve twice to position the diaphragm
correctly.
→
Without applying pressure, tighten the body screws to the permitted
tightening torque (see "Tab. 2: Tightening torques for diaphragms").
→
Pressurize the lower control air connection with compressed air
(value on type label).
→
Check the tightening torque of the screws again.
procedure for actuator with control functions b and i:
→
Place actuator on the body.
→
Gently tighten the body screws in diagonal pairs without pres-
surization until the diaphragm is between the body and actuator.
do not fully tighten screws yet.
→
Pressurize the lower control air connection with compressed air
(value on type label) (see following "Fig. 7: Control air connection").
→
Actuate the diaphragm valve twice.
→
Tighten the body screws to the permitted tightening torque
(see "Tab. 2: Tightening torques for diaphragms").
