Installation
The valve is normally shipped as part of a valve assembly, with the actuator, handlever, or handwheel mounted on the
valve. If the valve or actuator have been purchased separately, or if the actuator has been removed for maintenance,
mount the actuator on the valve, and adjust actuator travel before inserting the valve body into the line. This is
necessary due to the measurements that must be made during the actuator calibration adjustment process. Refer to
the Actuator Mounting section of this manual and to the separate actuator or handlever instruction manual for
mounting and adjustments before proceeding.
WARNING
Always wear protective gloves, clothing and eyewear when performing any installation or maintenance operations to
avoid personal injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given in this manual, the limits on the appropriate nameplates,
or the matching pipe flange rating. Use pressure-relieving devices as required by government or accepted industry codes
and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
