2. For use with soft seal only.
Installation
Key numbers in this procedure are shown in figures 13, 14, and 15 unless otherwise indicated.
WARNING
Always wear protective gloves, clothing and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the service
conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 4 or on the
nameplate. Use pressure‐relieving or pressure‐limiting devices to prevent the service conditions from exceeding these
limits.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section on page 10
in this manual.

CAUTION
The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop,
and controlled fluid conditions specified in the customer's order. Because some valve body/trim material combinations are
limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without
first contacting your Emerson sales office.
The maximum allowable inlet pressures for steel and stainless steel valve bodies are consistent with the
pressure‐temperature ratings shown in table 1, except where further limited by the trim and packing material
temperature capabilities given in table 4. Valves are also available in CW2M valve body materials. The CW2M valve
body material is not listed in ASME B16.34. Valve bodies constructed of this material mates with ASME flanges, but
must not be installed in systems requiring conformance to ASME standards if not included in ASME
pressure/temperature ratings. Maximum allowable inlet pressures for CL600 Control-Disk valve bodies made of CW2M
construction materials are shown in table 3.
1. Install a three‐valve bypass around the control valve assembly if continuous operation is necessary during
inspection and maintenance of the valve body.
2. Inspect the valve body to be certain it is free of foreign material.
3. The valve is normally shipped as part of a control valve assembly, with an actuator mounted on the valve body.
If the valve body and actuator have been purchased separately or if the actuator has been removed for maintenance,
mount the actuator, and adjust actuator travel to close the valve before inserting the valve body into the line. This is
necessary due to the measurements that must be made during the actuator adjustment process. Refer to the Actuator
Mounting section on page 22 of this manual and to the separate actuator instruction manual for mounting and
adjusting instructions before proceeding.
4. Inspect adjacent pipelines to be certain they are free of any foreign material, such as pipe scale or welding slag, that
could damage the valve body seating surfaces.
CAUTION
Damage to the disk (key 6) will occur if any pipe flanges or piping connected to the valve body interfere with the disk
rotation path. However, the disk can be rotated without interference when the valve body is installed between adjacent
pipe flanges or piping that has an inside diameter equal to or greater than either schedule 80 pipe or compatible EN pipe
sizes. If piping with a smaller inner diameter than specified above is connected to the valve, measure carefully to be certain
the disk rotates without interference before putting the valve into operation.
5. Flow is in the standard direction when the seal retainer (key 16) is facing downstream. Standard flow direction is
also indicated by the flow direction arrow cast into the valve body. Flow in the forward direction is permissible
within allowable pressure drop limits with the proper seal.
CAUTION
CL600 Control-Disk disk rotation is counterclockwise to open (when viewed from the actuator side of the valve body, see
figure 12) through 90 degrees of disk rotation.
6. With the disk in the closed position, install line flange gaskets, and insert the valve between the pipeline flanges.
Use either flat sheet gaskets or spiral‐wound gaskets with compression‐controlling centering rings. Spiral‐wound
gaskets without compression‐controlling centering rings are not recommended for this purpose.

Lifting Guidelines
Threaded holes for lifting are standard on the NPS 6 - 24 valve bodies. It is required that swivel hoists rings be used to
lift the valve or valve and actuator assembly. An eyebolt cannot accommodate all lifting angles required to install or
maintain the valve. The load carrying capability of an eyebolt decreases dramatically if used in any other orientation
than axially. Therefore, the use of eyebolts is not permitted.
CAUTION
Care must be taken when lifting the valve/actuator assembly to ensure the accessories and tubing are not damaged in the
process. The valve weight is listed in table 2. For the actuator weight, refer to the appropriate instruction manual. Make
sure to use appropriate lifting straps/hoists capable of lifting this combined weight.
WARNING
Avoid personal injury or property damage caused by uncontrolled movement or dropping of the valve assembly.
Ensure the disk is secure from rotating during lifting process. Failure to do so could result in personal injury if the disk
rotates uncontrolled during lifting.
Swivel Hoist rings are sized to lift only the valve and actuator. Do not attach piping or other structures to the valve and
actuator assembly when lifting with swivel hoists rings.
Take appropriate precautions to avoid unbalanced loading which may result in sudden swinging or movement of the
assembled unit, including additional lifting and/or support methods when necessary.
Do not use eyebolts when lifting the valve or valve and actuator assembly due to variable loading angles inherent to valve
maintenance and installation.
Failure to utilize safe lifting practices may result in equipment damage and/or personal injury.
Lifting Valve/Actuator Assembly
To lift the assembly, install swivel hoist rings into one or two of the threaded holes on the valve body (see figure 3.
Thread sizes are listed in table 5. When lifting the valve and actuator assembly, a strap around the actuator may be
required to ensure lifting stability. If straps are used on the actuator, ensure the lifting location is above the center of
gravity (CG) for the actuator to prevent load shifting during lifting. Refer to the appropriate assembly drawings for the
CG for your assembly.
Lifting Valve Only
To lift the valve, insert two swivel hoist rings into the body. Thread sizes are listed in table 5. Ensure the valve is closed
and that the packing is tightened to prevent shaft rotation during lifting. Without an actuator, the valve disk is free to
rotate if enough momentum is generated during the lifting process by a sudden stop. The packing and seal friction
should prevent the disk from rotating; however take proper precaution when lifting the valve.
7. Insert the valve between the flanges and install two or more line flange studs into the line flanges to help hold the
valve in position while centering the valve. Carefully center the valve on the flanges to ensure disk clearance.
Note
Lubricate line flange studs before inserting them into flanges. If necessary, provide additional support for the control valve
assembly because of its combined weight.

WARNING
For lugged valve bodies with threaded line bolt holes, personal injury and property damage could result from sudden
release of process pressure if line bolts are not properly installed. To ensure proper line bolt thread engagement, line studs
must be centered in the threaded section of the valve body so that each stud has equal thread engagement in the body. See
figure 5.
8. After centering the valve body, first lubricate and then install the remaining line flange bolting to secure the valve in
the pipeline. Tighten the nuts to the line flange studs in a crisscross pattern to ensure proper alignment of valve,
gaskets, and flanges.
WARNING
A CL600 Control-Disk valve body is not necessarily grounded when installed in a pipeline. If the valve is used in a flammable
or hazardous atmosphere or for oxygen service, an explosion could result due to a discharge of static electricity from the
valve components. To avoid personal injury or property damage, always make sure the valve body is grounded to the
pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.
Note
Standard packings for the CL600 Control-Disk valve are composed of all conductive packing rings (graphite ribbon packing) or
partially conductive packing rings (such as a carbon‐filled PTFE female adaptor with PTFE V‐ring packing) to electrically bond the

shaft to the valve body for hazardous area service. For oxygen service applications, provide alternate shaft‐to‐valve body bonding
according to the following step.
9. For oxygen service applications, attach the bonding strap assembly (key 34, figure 7) to the shaft with the clamp
(key 33, figure 7), and connect the other end of the bonding strap assembly to the valve body with the cap screw
(key 31).
WARNING
Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however, the packing
might require some readjustment to meet specific service conditions.
Figure 7. Optional Shaft‐to‐Valve Body Bonding Strap Assembly

Valves with ENVIRO‐SEAL packing systems will not require this initial re‐adjustment. See ENVIRO‐SEAL Packing System
for Rotary Valves Instruction Manual (D101643X012) for packing instructions. If you wish to convert your present
packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the parts kit sub‐section on page 23 of
this manual.
Maintenance
Valve body parts are subject to normal wear and must be inspected regularly and replaced as necessary. The frequency
of inspection and replacement depends upon the severity of service conditions. Instructions are given in this section
for: replacing trim components, changing disk rotation or valve action, and mounting and adjusting the actuator.
As used in these instructions, actuator refers to power actuators (such as pneumatic diaphragm, piston actuators, and
rack and pinion actuators).
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.
