Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure can result if the valve assembly is installed
where service conditions could exceed the pressure drop limits given in table 2 or the valve rating. To avoid such injury or
property damage, provide a relief valve for overpressure protection 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.
