4 Safety note for valves, certified to Clean Air Act (TA-Luft)
On request, this valve can be supplied compliant with
the German Clean Air Code.
Certificate / Manufacturer Declaration Validity is de-
pendent on the operating instructions being read and
observed. In particular, servicing must be conducted at regular
intervals, and the bolted connections relevant for
tightness must be inspected and retightened if neces-
sary.
5 Transport, storage and disposal
It is imperative, for all transport work, to ob-
serve generally accepted engineering practi-
ce and the accident prevention regulations.
The valve is supplied with flange caps. Do not
remove them until just before installation.
They protect the plastic surfaces against dirt
and mechanical damage.
Handle the goods being transported with care. During
transport the valve must be protected against impacts
and collisions.
Directly after receipt of the goods, the consignment
must be checked for completeness and any in-transit
damage.
Do not damage paint protection.
5.1 Storage
If the valve is not installed immediately after delivery,
it must be put into proper storage.
It should be stored in a dry, vibration-free and well-
ventilated room at as constant a temperature as pos-
sible.
Elastomers are to be protected against UV light.
In general, a storage period of 10 years should not be
exceeded.
It is not permitted to put the valve into store with the
disc completely closed or with an opening angle grea-
ter than 15°.
5.2 Transport preparations
During transport the disc/stem unit must not project
beyond the body dimensions.
Hand lever:
When the valve is in the closed position, the lever is to
lock in the first lever catch. This results in the
disc/stem unit being slightly opened.
Worm gear
When the valve is in the closed position, the disc/stem
unit is to be 10-15° open.
Actuator
When the valve is in the closed position, the disc/stem
unit is to be 10-15° open.
Attach a locking plate on shut-off and control butterfly
valves with a single-acting actuator. See also Section
6.4.1 and the drawing in Section 5.4.
Mount flange caps.
5.3 Return consignments
Valves which have conveyed aggressive or
toxic media must be well rinsed and cleaned
before being returned to the manufacturer's
works.
It is imperative to enclose a safety information
sheet / general safety certificate on the field of ap-
plication with the return consignment.
Pre-printed forms are enclosed with the installation
and operating manual.
Safety precautions and decontamination measures
are to be mentioned.
