WARNING
Avoid personal injury and property damage from ignition of process fluid caused by sparks from ceramic trim. Do not use
ceramic trim where the process fluid is unstable or if it is an explosive mixture (such as ether and air).
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 may result if the valve assembly is installed
where service conditions could exceed either the valve body rating or the mating pipe flange joint rating. To avoid such
injury or 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.

WARNING
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end‐user. To avoid possible personal injury and because
