CAUTION
• Ensure sucient space for easy and
safe operation and maintenance of
the control valve.
• Avoid installing the valve in a
location where vibration or external
stress may impair proper valve
functions. If necessary, make
appropriate provisions against these.
• Consider providing a support for
the valve, so that the process piping
is not burdened with the excessive
weight of valve, or provide supports
on the upstream and downstream
pipe runs.
• Provide a cover or protective fence
around the valve installation, when
a valve is installed facing a path
or if physical contact with valve is
expected.
• Do not install a valve where it is
submerged under the water, or snow or freezing may take place.
• Provide a wall for protection against heat radiation.
• Provide measures to protect the valve against salt spray or corrosive atmosphere.
• To stop operation of the Flowmeter:
- Switch the control equipment connected to the owmeter to manual control.
- To turn the power to the converter o.
CAUTION
• In order to guard against accident while handling the valve, always wear safety
gloves, goggles and safety shoes.
