• The valve, actuator, and accessories (if so equipped) are assembled, tested, and
calibrated at the factory. The actuator nameplate specifies set-up parameters
used (See Information Present on Control Valves section for location of impor-
tant information on valve). Do not exceed the supply pressure listed on the
actuator nameplate or you will damage the valve and void the warranty.
• Supply air or voltage, instrument signal, and accessories should be connected
to ports or terminals as indicated on the control valve.
• Final tuning may be required under actual operating conditions.
• On critical or dangerous equipment, provide suitable safety and emergency
systems to protect personnel and property from injury due to a valve malfunc-
tion. If the valve handles flammable, toxic, corrosive or explosive fluids, pro-
vide for safety in the event of valve leakage or malfunction.
• Do not obscure flow arrow plates or nameplates with paint. If flow arrow plates
or nameplates will be covered with insulation, it is recommended the informa-
tion on the plates be transcribed on the outside of the insulation in the same
location as the plate.

ate valve using handwheel
