Valve Installation

CAUTION WARNING

This valve is intended for a specificrange of pressures, temperatures and other application specifications.Applying different pressure andtemperatures to the valve could result in parts damage, malfunction of thecontrol valve or loss of control of theprocess. Always wear protective gloves,clothing, and eyewear when performing any installation operationsto avoid personal injury.Personal injury or equipment damagecaused by sudden release of pressureor bursting of pressure retaining parts might result if service conditionsexceed those for which the productwas intended. To avoid injury or damage, provide a relief valve for overpressure protection as required bygovernment or accepted industry codes and good engineering practices.Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.If installing into an existingapplication, also refer to the WARNING at the beginning of the Maintenancesection in this instruction manual. Do not expose this product toservice conditions or variables otherthan those for which the product wasintended. If you are not sure whatthese conditions are you shouldcontact your Emerson ProcessManagement sales office for more complete specifications. Provide theproduct serial number (shown on thenameplate, figure 2) and all other pertinent information.

WARNING

If you move or work on an actuator installed on a valve with loading pressure applied, keep your hands andtools away from the stem travel path to
