8.4 Pneumatic connection
Danger!
danger – high pressure in the equipment!
▶ Before loosening the lines and valves, turn off the pressure and
vent the lines.
Warning!
for control function i – danger if pilot pressure fails!
For control function I control and resetting occur pneumatically.
If the pressure fails, no defined position is reached.
▶ To ensure a controlled restart, first pressurize the device with pilot
pressure, then switch on the medium.

Open-end wrench
risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶ Use only hoses which are authorized for the indicated pressure
and temperature range.
▶ Observe the data sheet specifications from the hose
manufacturers.
The pneumatic connection of the angle-seat control valve
can be carried out only in connection with the appropriate
control unit.
Possible control units are:
Positioner Type 8692, 8694, 8696 and 8792;
Process controller Type 8693 and 8793.
8.4.1 connection of the control medium
→
Connect the control medium to the pilot air port ("Fig. 8": 1)
(3 – 7 bar; instrument air, free of oil, water and dust).
→
Fit the exhaust line or a silencer to the exhaust air port ("Fig. 8":
3) and, if available, to the additional exhaust air port ("Fig. 8": 3.1).
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.
