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. Attachments such as actuators, position control-
lers, limit switches etc. must satisfy the relevant
safety regulations as regards explosion protection
and, if required, be designed in compliance with
ATEX.
Special attention must be paid to the appropriate
safety and explosion protection notes in the
respective operating manuals.
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, storage and disposal
It is imperative, for all transport work, to
observe generally accepted engineering
practice 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 the external epoxy coating.
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
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
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
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.
5.3 Disposal
Parts of the valve may be contaminated with medium
which is detrimental to health and the environment and
therefore cleaning is not sufficient.
Risk of personal injury or damage to the
environment due to the medium!
Wear protective clothing when work is performed
on the valve.
Prior to the disposal of the valve:
Collect any medium, etc. which has escaped
and dispose of it in accordance with the local
regulations.
Neutralise any medium residues in the valve.
Separate valve materials (plastics, metals, etc.)
and dispose of them in accordance with the local
regulations.
