Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.
To avoid personal injury or property damage caused by bursting of pressure-retaining parts or by uncontrolled process fluid, be certain the service conditions do not exceed the limits shown on the valve nameplate and in table 1. Use pressure-relieving devices 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.
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 body/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson Process Management sales office.
To avoid product damage, inspect the valve before installation for any damage or any foreign material that may have collected in the valve body. Also remove any pipe scale, welding slag, or other foreign material from the pipeline.
1. Before installing the control valve assembly, inspect it for any damage and for any foreign material that may have
collected in the valve body.
2. Clean out all pipelines to remove scale, welding slag, and other foreign materials.

4. Install the valve following local and national piping codes when they apply to the application. For screwed
connections, treat the external pipe threads with a good grade pipe compound. For flanged connections, use suitable gaskets between valve and pipeline flanges.
5. If continuous operation is required during inspection or maintenance, install a three-valve bypass around the
control valve assembly.
6. Connect loading pressure for the Spring-to-Close configuration to the lower casing assembly (key 21) as shown in
figure 7. The Spring-to-Open configuration loading pressure connection is in the upper casing assembly (key 32) as showninfigure8.

Maintenance
Refer to figures 7 and 8.
Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and maintenance depends on the severity of the service conditions.
WARNING
Avoid personal injury from sudden release of process pressure or bursting of parts. Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the power actuator loading pressure.
D Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
