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 may result if the valve assembly is installed
where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or
damage, provide a suitable overpressure protection device as required by local, state, and Federal 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.
CAUTION
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. Since some valve body/trim material
combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions t o the valve
without first contacting your Emerson Process Management sales office.
If hoisting the valve, the use of a nylon sling is recommended to protect the painted surfaces. Also be careful to position the
sling so there will be no damage to the tubing or any accessories.
1. Before installing the valve, inspect the valve body and associated equipment for any damage and any foreign
material. Make certain that the valve body interior is clean, pipelines are free of foreign material, and the valve is
orientedsothatpipelineflowisinthesamedirectionasthearrowonthesideofthevalvebody.
