OPERATING AND SAFETY INSTRUCTIONS

Before installation, these instructions must be fully read and understood

PRECAUTIONS

WARNING

For safety reasons, it is important to take the
following precautions before you start work on
the valve:

1. Personnel making any adjustments to the
valves should utilize suitable equipment. All
required personal protection means should
be worn.

2. Caution must be taken during installation and
full responsibility lies with those responsible
for the complete installation. In any case, the
local safety regulations must be respected.

3. The line must be depressurized before
installing the valve. In case of dangerous
pipeline fluids, the pipeline should be drained
and flushed properly with an appropriate
cleaning fluid.

4. Misuse of the valve is not allowed. For
example: the valve, handles, actuators or other
parts may not be used as “climbing tools”.

5. Pressure and temperature ratings of the valve
must be adhered to and need to be checked
with the system specifications. See the
Maintenance and installation instructions for
P/T diagrams.

6. Ensure that valve materials are compatible
with the pipeline fluid.

7. Detailed information for installation and
maintenance is available.

INSTALLATION

1. Handling and lifting should be performed
according the maintenance and installation
instructions.

2. All valves are bi-directional unless fitted
with a flow direction arrow. If a directional
arrow is fitted then the valve must be
installed with the arrow pointing in the
direction of the flow.

3. For detailed installation instructions
refer to the maintenance and installation
instructions for the specific product.

4. Do not use the valve to spread the flanges.

5. In case the valve is used as spool piece
during erection of piping, do not finish weld
the flanges to the pipes with the valve bolted
between the flanges as this will result in
serious heat-damage to the seat.

MAINTENANCE

!! Read all warning labels fitted to the valve before
operation or maintenance !!

• Check the valve’s functionality on a regular
basis.

• No additional routine maintenance is
required.

REPAIR

WARNING

The line must be depressurized before carrying
out any repairs to the valve. In case of dangerous
pipeline fluids, the pipeline should be drained and
flushed with an appropriate cleaning fluid. Failure
to do so may cause serious personal injury and/
or equipment damage. Before disassembling the
valve ensure the valve has been decontaminated
correctly from any harmful gasses or liquids
and that it is within a safe temperature range for
handling. Personnel making any adjustments
to the valves should utilize suitable equipment.
All required personal protection means should
be worn. Only qualified personnel trained in all
aspects of manual and mechanical handling
techniques must carry out lifting and handling
of valves.

Hazard potentials

• Disregarding of instructions

• Improper use of product

• Insufficiently qualified personnel

Ensure that valve materials are compatible
with the pipeline fluid.

Valve application to be within the pressure/
temperature limits indicated in the P/T diagram
of the product manual.

If in doubt, contact factory.

Check the valve’s functionality on a regular
