Installation

!

WARNING

Only qualified 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 

Management Regulator Technologies, 

Inc. instructions.
If the switching valve vents fluid 

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 fluid 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 Specifications 

section, or where conditions exceed 

any ratings of the adjacent piping or 

piping connections.
