Leakage butterfly valve with handle HB04
Rev.1/ 28.09.2009 Seite 8 von 12 BA59540HB04GB.doc
• On assembly it is absolutely necessary to pay attention to the in-
stallation of the floating bearings (16)!!
• On assembly of flap (17+21) and seal (18), pay attention not to
spoil the axis boring of the seal.
• The set screws (11) of the leakage seat valves have to be
screwed tightly.
• Pay attention to the position of the leakage seat valve. Observe
the turning direction of the handle.
• Damages on the seal are to be avoided.
• Counter flanges have to be aligning to each other and are to be
adjusted accordant to definite position.
• Assemble the butterfly valve in a way assuring to avoid damages
(for example by means of material-handling vehicles).
• Take care of the respective national subscriptions and assigna-
tions.
• Protect butterfly valves and connections from damage and de-
struction.
• The butterfly valve is to be implied in the potential equalization by
means of appropriate assembly.
6.3 Installation / Starting up
• Leakage butterfly valve are to be installed only by qualified per-
sonnel, with adequate functional training, experience and knowl-
edge regarding the tasks conferred to them.
• Pay attention that:
- the leakage butterfly valve is installed zero-potential
- no objects (screws, tools, etc.) are included in the tube system.
- the thermal expansion of a medium “cooped in” and pressure
hammers cannot affect the flap. Accordant non-return valves and
relief valves should be provided.
6.4 Valve with welding sockets
• In the welding process, shape distortion can result which may af-
fect the function of the leakage butterfly valve. For this reason,
only weld butterfly valve flanges assembled without seal and flap.
For this, pull tight all screws.
7 Maintenance / Attendance
• It is not allowed to make modifications on the leakage butterfly
valve.
