If the valve is heated (e.g. heating jacket), it must
be ensured that the temperature classes pre-
scribed in the Annex are observed.
To achieve safe and reliable operation, it must be
ensured in inspections at regular intervals that the
valve is properly serviced and kept in technically
perfect order.
Increased wear to the valve can be expected with
the conveyance of liquids containing abrasive
constituents. The inspection intervals are to be
reduced compared with the usual times. Actuators and electric peripherals, such as
temperature, pressure and flow sensors etc., must
comply with the valid safety requirements and
explosion protection provisions.
The valve must be grounded.
This can be achieved in the simplest way via the
pipe screws using tooth lock washers.
Otherwise grounding must be ensured by other
action, e.g. cable bridges.
Plastic-lined valves must not be operated with
carbon disulphide.
4 Safety note for valves, certified to German Clean Air Act
(TA-Luft)
On request, this valve can be supplied compliant with
the German Clean Air Code.
Certificate / Manufacturer Declaration Validity is
dependent 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
necessary.
5 Transport and storage
It is imperative, for all transport work, to
observe generally accepted engineering
practice and the accident prevention
regulations.
The cylindrical sight glass 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 sight glass 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 epoxy coating.
5.1 Storage
If the sight glass 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
possible.
Elastomers are to be protected against UV light.
In general, a storage period of 10 years should not be
exceeded.
5.2 Return consignments
Sight glasses which have conveyed aggres-
sive 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
application with the return consignment.
Pre-printed forms are enclosed with the installation
and operating manual.
Safety precautions and decontamination measures
are to be mentioned.
