Operation
7 Operation
As soon as the commissioning/recommissioning work is
complete without any defects, see Chapter “6 Start-up”, the valve
is ready for operation.
Danger due to jerky operation of the valve!
The failure to observe these warnings can cause extreme danger
for persons or damage to the pipe system.
Ö
Do not open and close the butter fl y valve suddenly to prevent
pressure surges and/or a temperature shock in the pipe
system.
Danger of burning due to hot or cold components and pipe!
Butter fl y valves and pipes can become very hot or very cold
during operation and cause burns upon contact.
Ö
Let the components and pipes cool down or warm up.
Ö
Wear protective garments and protective gloves.
Danger of injury due to pressurised components and escaping
medium!
Ö
Pressurised components may not be loosened.
Hearing damage and deafness due to a high sound level!
During operation, medium-related noise emissions may be
generated depending on the plant conditions. In addition, there
may be a short-term high sound pressure level when a pneumatic
actuator or pneumatic attachment is suddenly ventilated without
noise-reducing elements. Both can damage hearing.
Ö
Wear hearing protection when working in the vicinity of the
actuator.
Danger of crushing due to moving parts
The valve contains moving parts (e.g. shaft and wedge-lock-
washer) that can lead to crushing if reaching into it.
Ö
During operation, do not reach into the bracket between the
butter
fl y valve and the actuator.
Ö
Before working on the valve, interrupt and lock the pneumatic
energy and the control signal.
Ö
Do not allow the jamming of objects in the bracket to hinder
the rotation of the shaft.
Ö
In the case of a blocked shaft, contact PFEIFFER.
Danger of injury due to escaping exhaust air!
During operation, when regulating or when opening and closing
the butter
fl y valve, exhaust air can escape, for example from the
actuator.
Ö
Wear eye protection when working in the vicinity of the
actuator.
DANGER
WARNING
After commissioning and reaching the operating temperature, it
may be necessary to retighten the screw connections on the body
parts with the corresponding tightening torques, see Chapter
“15.1.1 Tightening torques”.
If an valve leaks, see chapter “8 Malfunction”.
7.1 Working in automatic mode
For actuators with additional manual adjustment, bring them into
a neutral position recommended by the manufacturer. Further
information can be found in the respective component
instructions.
Butter fl y valves that were delivered from the factory with an
actuator are precisely adjusted. The user is responsible for any
changes they make.
7.2 Working in manual mode
For actuators with manual adjustment, the butter fl y valve can be
opened and closed manually if the pneumatic energy fails.
Further information can be found in the respective component
instructions.
7.3 Working with the manual gear
For butter fl y valves with manual adjustment, they can be opened
and closed manually. Further information can be found in the
respective component instructions.
