WARNING

Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal

injury.

Personal injury or property damage caused by sudden release of pressure or bursting of pressure retaining parts may result

if service conditions exceed those for which the product was intended. To avoid injury or damage, provide a relief valve for

over pressure 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.

CAUTION

This actuator is intended for a specific range of pressures, temperatures and other application specifications. Applying

different pressures and temperatures to the actuator could result in parts damage, malfunction of the actuator or loss of

control of the process. Do not expose this product to service conditions or variables other than those for which the product

was intended. If you are not sure what these conditions are you should contact your Emerson sales office for more

complete specifications. Provide the product serial numbers (shown on the nameplate) and all other pertinent information.

WARNING

If you move or work on an actuator installed on a valve with loading pressure applied, keep your hands and tools away

from the stem travel path to avoid personal injury. Be especially careful when removing the stem connector to release all

loading on the actuator stem.

Likewise take similar care when adjusting or removing any optional travel stop. Refer to the relevant actuator Maintenance

Instructions.

If hoisting the valve, take care to prevent people from being injured in case the hoist or rigging slips. Be sure to use

adequate sized hoists and chains or slings to handle the valve.

WARNING

Personal injury could result from packing leakage. Valve packing is tightened before shipment; however, the packing

might require some readjustment to meet specific service conditions.

Maintenance

WARNING

Avoid personal injury and property damage 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.

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 Use lock‐out procedures to be sure 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 when removing the packing hardware or packing rings, or when loosening the

packing box pipe plug.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

Note

It is recommended that you review figure 2 before performing maintenance or installation of the CML electric actuator.

Recommended Installation Location

It is permissible to install the CML actuator upright or horizontally. Allow 12 inches of clearance for removal of the

actuator. Do not install with the actuator below the pipe.

CAUTION

To avoid equipment damage, do not install the valve with the stem in a downward position. Equipment damage may occur

from liquids leaking into the actuator cover.

Installation

See table 2 for actuator parts/key numbers referenced in this Installation section. See table 3 and also refer to the

appropriate Baumann valve instruction manual for valve parts referenced.

1. Before starting, ensure you have the correct actuator part number and locate the parts listed in table 2. Refer to the

assembly instructions for the appropriate Baumann control valve for parts identification.

2. Place the valve body (key1) in a vise. Clamp the flat end faces of the valve. DO NOT CLAMP THE SIDES OF THE

VALVE. This may distort the shape of the casting and ruin the valve.

3. Push the valve stem (key 5) to the closed position. Install the two lock nuts (key 27) onto the stem (key 25).

4. Slowly lower the actuator down on the valve body (key 1). As the yoke (key 17) passes over the end of the valve

stem (key 5), place the yoke drive nut (key 9) over the valve stem (key 5).

5. Screw the yoke drive nut (key 9) on to the bonnet (key 8) and tighten.

6. Place travel indicator disc (key 58) onto the valve stem (key 5).

7. For CML 750: Skip to step 10.

8. For CML 250: Remove the drive nut (supplied with actuator) from the base of the actuator and set the upper drive

nut over the valve stem (key 5).

9. Place the spacer (key 68) on top of the actuator yoke (key 17) over the opening.

10. Set the actuator on top of the actuator yoke (key 17) and prepare for mounting

11. Lift the valve stem (key 5) with the travel indicator (key 58) and hold it. Spin the actuator onto top of the yoke (key

17) to screw the actuator stem onto the valve stem (key 5) by 9 full turns. The actuator should be facing forward

when engagement is complete.

For the CML750 align the four bolt holes in the yoke (key 17) with the bolt holes in the actuator with the actuator

facing forward.

12. For the CML 250 tighten the upper lock nut (supplied with actuator) on the actuator thread.

For the CML750 install the 4 cap screws (key 5) and tighten to 20 ftSlbs.

13. Raise the top lock nut (key 27) and lock travel indicator (key 58) on top. Then raise the lower lock nut (key 27) and

lock in place to secure travel indicator (key 58) tight against the actuator stem.
