Safety instructions and safety measures
Danger due to falling of suspended loads!
Ö
Do not stand under suspended loads.
Ö
Secure the transport paths.
Danger due to escaping medium as a result of unsuitable
fl ange seals
Leaks caused by unsuitable fl ange seals can cause operating
medium to escape. Flange leaks can cause fatal injury to
personnel and damage the environment.
Ö
Use suitable fl ange seals.
Ö
Request special dimensions from PFEIFFER.
1.2 Notes regarding possible personnel injury
The following list indicates only generally-applicable warning in-
formation. The respective chapters can contain warning informa-
tion that, due to context, is provided in addition or is formulated
slightly differently.
Danger of burning due to hot or cold components and pipes!
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.
Hearing damage and deafness due to a high sound level!
Noise emissions depend on the version of the valve, the plant
equipment as well as the utilised medium. 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
valve.
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
Install the valve such that the actuator does not ventilate at
eye level.
Ö
Use suitable silencers and plugs.
Ö
Wear eye protection when working in the vicinity of the
actuator.
Danger of injury due to incorrect lifting without lifting
equipment!
When lifting the valve without lifting equipment, injuries may oc-
cur, especially in the torso area, depending on the weight of the
valve.
Ö
Observe the occupational health and safety regulations ap-
plicable at the installation site.
DANGER
WARNING
Overturning of the lifting equipment and damage to the load
lifting equipment by exceeding the lifting capacity!
Ö
Only use approved lifting equipment and load lifting equip-
ment whose lifting capacity corresponds at least to the weight
of the valve and the packaging if applicable.
Danger of crushing due to moving parts!
The butter fl y 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 preloaded springs!
Valves that are equipped with preloaded actuator springs are un-
der mechanical tension. The marking on the actuator type plate
indicates whether a spring return is available and the fail-safe
position. The marking on the type plates is described in the in-
struction manuals for the actuators.
Ö
Release the compression from the preloaded springs before
working on the actuator, see the corresponding actuator
documentation.
Danger of injury due to moving parts with spring-loaded
actuators
Spring-loaded actuators may only be pressurised when installed
in the pipe and not to perform work on the valve outside of the
pipe. There is risk of fatal injury if the pneumatic energy
suddenly fails and the valve disc moves automatically to the fail-
safe position by means of spring force.
For devices that have a spring-loaded actuator with a “fail open”
fail-safe position, the control and shut-off valve must be installed
in the open position, for example by removing the pipe.
The sealing surfaces may not be damaged during this operation.
Danger of injury due to residual medium in the butter fl y valve!
When working on the butter fl y valve, residual medium can
escape and, depending on the medium properties, cause injuries
(e.g. scalding, chemical burns).
Ö
If possible, empty the medium from the concerned plant parts
and control and shut-off valve.
Ö
Wear protective garments, protective gloves and eye protec-
tion.
Danger of injury due to pressurised components and escaping
medium!
Ö
Do not loosen pressurised components.
Danger of injury due to static charge
Ö
If there is a risk of static charge of the butter fl y valve, the op-
erator must ensure, to avoid it, that a suitable ground con-
nection is installed in the provided position.
