WARNING
Only qualied personnel should install
or service a switching valve. Switching
valves should be installed, operated,
and maintained in accordance with
international and applicable codes and
regulations, and Emerson Process

If the switching valve vents uid
or a leak develops in the system, it
indicates that service is required.
Failure to take the switching valve out
of service immediately may create a
hazardous condition.
Personal injury, equipment damage,
or leakage due to escaping uid or
bursting of pressure-containing parts
may result if this switching valve is
overpressured or is installed where
service conditions could exceed the
limits given in the Specications
section, or where conditions exceed
any ratings of the adjacent piping or
piping connections.
