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 sales office or Local Business Partner.
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.
3. The control valve assembly may be installed in any orientation, but normally the actuator is vertical above the valve.
Install the valve so the flow direction arrow on the side of the valve indicates the direction of the process flow.

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
shown in figure 8.

Setting the Valve FloPro Flow Adjuster
The flow setting may only be adjusted if the 0.375 and 0.75 inch port sizes are installed.
When shipped from the factory, the actuator has the FloPro flow adjuster set at the maximum flow rate position for
the given port size.
Spring‐to‐Close Actuator Action
1. Ensure the valve plug is in the seated position.
2. To change the valve flow rate, loosen the flow adjuster socket head cap screws (key 15), and reposition the flow
adjuster halves (key 13 and 14) to the desired flow rate position. See figure 2 for flow rate settings.
3. Retighten the socket head screws (key 15) to 3 NSm (26 lbfSin).
Spring‐to‐Open Actuator Action
1. Attach a pressure line to the actuator. Pressurize the actuator to a maximum of 2.41 bar (35 psi) to seat the plug in
the seat ring.
2. To change the valve flow rate, loosen the flow adjuster socket head cap screws (key 15), and reposition the flow
adjuster halves (key 13 and 14) to the desired flow rate position. See figure 2 for flow rate settings.

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.

Key numbers are referenced in figure 7.
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body (key 1), and drain
the process media from both sides of the valve.
CAUTION
The following steps are intended to prevent damage to the valve plug (key 3) and seat ring (key 2) during the removal of
the bonnet and actuator.
2. Pressurize the actuator to a maximum of 2.41 bar (35 psi) to stroke the valve to mid travel. This will raise the valve
plug (key 3) off its seat and expose all of the serrations on the valve stem (key 16).
3. Loosen the hex socket head cap screws (key 15) and lower the flow adjuster (keys 13 and 14) to its lowest position
on the valve stem.
4. Tighten the hex socket head cap screws to 3 NSm (26 lbfSin).
5. Relieve pressure to the actuator, shut off all pressure lines to the actuator, and disconnect. Use lockout procedures
to ensure the above measures stay in effect while you work on the equipment.
