** seat/plug PTFE carbon
The diagram shows the max. admissible pressure /
temperature loading of the body.
When used in the minus temperature range,
the regulations applicable in the country in
question must be observed.
For applications under -10 °C (14 °F) to -60 °C (-
76 °F) a special material must be selected for the
thrust flange and spindle.
For applications in the range covered by ASME or

limited to -20 °F (-29 °C).
2 Safety
This operating manual contains fundamental
information which is to be observed during installation,
operation and maintenance. It must therefore be

Installation and operation are to be performed by
qualified staff.
The area of responsibility, authority and supervision of
the staff must be regulated by the customer.
General hazard symbol !
Peoples may be put at risk.
Safety symbol ! The valve and its function
may be put at risk if this safety symbol is not
observed..
It is imperative to observe warnings and signs

fully legible.
Non-observance of the notes on safety may result
in the loss of any and all claims for damages.
For example, non-observance may involve the
following hazards:
Failure of important functions of the valve/plant.
Risk to people from electric, mechanical and
chemical effects.
Risk to the environment through leaks of
hazardous substances.
