Installation
Type 2380
→
Assemble O-ring 1 again.
→
Before assembling actuator with controller to the valve body
again, the valve must be open!
→
Check correct position of bellow and O-rings.
→
Fix the actuator again by tightening the 4 valve body screws with
a tightening torque of 3.5 Nm.
Valve body screws (4x)
Actuator with bellow
Ports for control air
(port 3 and port 1)
Controller (e.g. Type 8696)
Leakage detection bore (2x)

WARNING!
Danger – high pressure in the system!
▶
Before dismounting the lines and valves, turn off the pressure
and vent the lines.
WARNING!
Risk of injury from unsuitable connections!
Hoses or pipes which cannot withstand the pressure and tempe-
rature range may result in hazardous situations.
▶
Only use connections which are authorized for the indicated
pressure and temperature range.
▶
Observe the data sheet specifications from the manufacturers.
Observe for a proper functioning of the device:
▶
The installation must not cause back pressure to build up.
▶
Connection tubes with a sufficient cross section must be
selected.
▶
The exhaust air line must be designed in such a way that
no water or other liquid can get into the device through the
exhaust air port (3).
▶
During operation, keep the fluctuations of the control
pressure as low as possible (max. ±10 %). If fluctuations are
greater, the control parameters measured with the
X.TUNE
function are not optimal.
Connection of the control air
(see „Fig. 7“)
→
Connect the control air to the control air port (1) of the controller
Type 869x.
→
Mount an exhaust air line or a silencer to the exhaust air port (3).
If used in an aggressive environment, we recommend con-
veying all free pneumatic connections into a neutral atmos-
phere with the aid of a pneumatic hose.
