1 GENERAL INFORMATION ON THE
INSTALLATION AND MAINTENANCE
INSTRUCTIONS

These instructions contain information on
how the valve should be safely installed and
operated in the prescribed manner. If any
problems are encountered during installation
or operation which cannot be resolved with
the aid of the installation and maintenance
instructions, please contact the supplier or
manufacturer for more information.
These installation and maintenance
instructions comply with the applicable
ENsafety standards.
When installing the fitting, the operator or
the person responsible for the design of
the installation must ensure that applicable
national regulations are complied with.
The manufacturer reserves all rights to
maketechnical changes and improvements
atany time.
The use of these installation and maintenance
instructions assumes that the user is qualified
to “Qualified Personnel” level. Operating staff
must be given appropriate training in the
operating and maintenance instructions.

valves that can be used for the isolation,
throttling and regulation of corrosive gases,
liquids, pastes and powder products in
pipelines, vessels, apparatus etc.
The surfaces of the of the body parts, together
with the ball or C-core that are in contact
with the medium are coated with PFA. Ball
seats and control orifice plates are available
in various material types and can be used to
suitthe medium.

2.2.5 Usage restrictions

Before the valve is installed, a check should be
made on the extent to which the coating of the
surfaces is resistant to the intended medium.
The same applies to stainless steel valves with
no additional coating. Refer to appropriate
literature or consult the manufacturer or
distributor for advice on this.

2.2.6 Modification prohibition

Mechanical modifications to the valves or the
use of other manufacturer’s parts for repair
purposes are not permissible, as otherwise
safety is no longer guaranteed. Repair work
must only be carried out by the manufacturer’s
trained personnel. The manufacturer and
supplier will accept no liability in the event
ofmisuse.

2.2.7 Warning about foreseeable misuse

Valves and their accessories (e.g. operating
elements) must not be misused as
climbingaids.

2.2.8 Duty to comply with the instructions
foroperation, maintenance and servicing

These instructions form part of the delivery
package and must be easily accessible to the
user. They should be protected from soiling
andkept in a suitable place.

3 SOURCES OF DANGER

3.1 External chemical effects

The valve body is either made of stainless steel
or is coated with a 2-part polyester paint. The
coating can be attacked externally by strong
solvents, leading to corrosion of the body.
If damage of this nature occurs, the effects
on the environment should be investigated
and the damage to the coating made good
in accordance with the manufacturer’s data.
Stainless steel valve bodies are not suitable
foruse with chlorine gas.

3.2 Mechanical

When using hand levers and handwheels,
it should be ensured that there is sufficient
clearance everywhere for the operator’s
hands,so that there is no risk of trapping.

3.3 Electrical

If static charges can lead to explosions,
the valve must be earthed by means of
the appropriate earthing accessory. As an
alternative, valves with electrically conductive
linings are available. For more information,
please contact the supplier or manufacturer.

3.4 Thermal

The operating temperature of the valve can
be up to a maximum of 200°C. Suitable
precautions should be taken to protect against
burns due to high or freezing temperatures.
In particular, insulated gloves should be worn
when using the hand lever, for example. In case
of fire, the mechanical strength of the PTFE
seals is no longer guaranteed above 200°C.

3.5 Requirements for the operator

This means people who are familiar with the
erection, installation, commissioning, operation
and maintenance of the product and have
appropriate qualifications relating to their
activities and functions, such as e.g.:

- Instruction in and duty to comply with all
installation-related, regional and internal
works regulations and requirements.

- Training or instruction in accordance with the
Safety Standards for personal care and use of
appropriate safety equipment and protective
workgear, like e.g. personal protection
equipment (insulated gloves or similar),
suitable for the operating conditions.

Furthermore, these people must have read
andunderstood these instructions.

3.6 Transport/storage

The valve is delivered with protective covers
which should protect against soiling and
mechanical effects. For this reason, the
protective covers should only be removed
immediately prior to installation.
The ball valve is shipped in the closed position.

3.7 Transport and storage conditions

- Transport and storage temperature

-20°C to +65°C.

- Protect against external force(impact,
shock,vibration).

- Do not damage the coating.

- In damp storage areas, a drying agent
or heating is required to protect against
condensation.

- Store the ball valve in a slightly open position.

3.8 Handling prior to installation

- On versions with protective covers,
only remove these immediately prior
toinstallation!

- Protect against the effects of weather,
e.g.dampness (or else use a drying agent).

- Proper treatment prevents damage.

4 IDENTIFICATION

Each ball valve is fitted with a rating plate giving
information on valve type and origin. When
ordering spare parts this information should
becarefully noted down each time.
Ball valves in the size range DN 15 to DN 25
have a standard rating plate with no CE mark.
Ball valves in the size range DN 40 to DN 150
are provided with a rating plate with a CE mark.
Additional identification on the valve in
accordance with DIN19, such as: DN, PN,
manufacturer’s logos of the Neotecha AG
company . The identification of the valve
body material is cast onto the valve.

5 DIMENSIONS AND WEIGHTS

Please refer to the product documentation
for any dimensions that are not contained in
the installation and maintenance instructions
andfor ball valve weights.

6 INSTALLATION

6.1 Installation in the pipeline

Fit the ball valve in the pipeline, ensuring that
the sealing surfaces on the faces of the flanges
are not damaged. The NTB ball valve can be
installed independently of the direction of
flow. On the other hand, the NTC can only be
installed in one direction, i.e. the arrow on the
side of the valve must point in the direction of
flow. Adequate clearance should be ensured
around the ball valve, so that it can be operated
and maintained easily.
The mounting flanges of the pipeline in which
the valve is to be installed must be aligned
axially and laterally, in order to prevent the
valve body being subjected to additional
stresses. Fit suitable flange packings, provided
that they are called for: then the fixing bolts
are inserted. Tightening the bolts in stages is
essential for an equal distribution of the of the
initial stress force of the clamping bolts.
The specified tightening torques must not
beexceeded.

The flanges must meet the following
requirements: cleaned and undamaged
matingsurface.

Flange packings are not required with flanges
with flat sealing surfaces. Additional packings
may possibly be required with rubberized
flanges.
