4. Function
BE8H series valves are designed to shut off the medium flow. The type of working
medium may make some materials unsuitable for use. Valves are designed for normal
working conditions. Working pressure is related to the maximum temperature of the
medium as shown in the table below.

7. Installation
During the installation of the Bellows Sealed Valve the following steps should be
observed:
・
Visually inspect the valve initially to ensure it is undamaged and also ensure that it
is suited to the medium and working conditions used in the plant.
・
Remove dust caps if supplied.
・
Protect the valve during installation from debris and excessive temperature
conditions.
・
Steam pipelines should be fitted in such a way as to avoid condensate collection; in
order to avoid water hammer, a steam trap should be installed.
