Valve Installation

If you are not sure whatthese conditions are you shouldcontact your Emerson Process Management sales office for morecomplete specifications. Provide theproduct serial number (shown on the nameplate, figure 2) and all other pertinent information.

WARNING

Always wear protective gloves,clothing, and eyewear whenperforming any installation operations to avoid personal injury.Personal injury or equipment damagecaused by sudden release of pressureor bursting of pressure retaining partsmight result if service conditions exceed those for which the productwas intended. To avoid injury ordamage, provide a relief valve for over pressure protection as required bygovernment or accepted industrycodes and good engineering practices.Check with your process or safetyengineer for any additional measures that must be taken to protect againstprocess media.If installing into an existingapplication, also refer to the WARNINGat the beginning of the Maintenance section in this instruction manual.

WARNING

If you move or work on an actuatorinstalled on a valve with loadingpressure applied, keep your hands and tools away from the stem travel path toavoid personal injury. Be especiallycareful when removing the stem connector to release all loading on theactuator stem whether it be from airpressure on the diaphragm or compression in the actuator springs.Likewise take similar care whenadjusting or removing any optional travel stop. Refer to the relevantactuator Maintenance Instructions.If hoisting the valve take care toprevent people from being injured incase the hoist or rigging slips. Be sure to use adequately sized hoists andchains or slings to handle the valve.

CAUTION

This valve is intended for a specific range of pressures, temperatures and other application specifications.Applying different pressure and temperatures to the valve could resultin parts damage, malfunction of thecontrol valve or loss of control of the process.
