Introduction
Scope of Manual
This instruction manual provides installation, operation, maintenance, and parts ordering information for NPS 3
through 12 Fisher CV500 Cam Vee‐Ball™rotary control valves. Refer to separate manuals for information concerning
the actuator and accessories.
Description
The CV500 Cam‐Vee‐Ball rotary control valve, has a Vee‐Ball style segmented ball in a valve body similar to the V500
valve. The CV500 is a flanged valve (figure 1) with a self‐centering seat, eccentrically rotating V‐notch ball, and splined
valve shaft. Suitable for forward or reverse flow use, this valve mates with a variety of actuators to provide throttling or
on‐off service. The flanged valve mates with ASME flanges or EN flanges.
Do not install, operate, or maintain a CV500 valve without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

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 can result if the valve assembly is installed
where service conditions could exceed the pressure drop limits given in table 2 or the valve rating. To avoid such injury or
property damage, provide a relief valve for overpressure 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
When ordered, the valve configuration and construction materials were selected to meet particular pressure, pressure
drop, temperature, 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 range capabilities, do not apply any other conditions to the valve without first contacting your Emerson sales
office or Local Business Partner.

Key numbers are shown in figure 9 for NPS 3 through 8 and in figure 10 for NPS 10 and 12.
1. If the valve body (key 1) is to be stored before installation, protect the flange mating surfaces and keep the valve
body cavity dry and clear of foreign material.
2. Install a three‐valve bypass around the control valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
3. A CV500 valve is normally shipped as part of a control valve assembly, with a power or manual actuator mounted on
the valve. If the valve and actuator have been purchased separately or if the actuator has been removed from the
valve, mount the actuator according to the actuator instruction manual. Also, adjust the actuator travel using the
Adjusting Actuator Travel procedure in this manual before installing the valve; the required measurements cannot
be made with the valve installed.
4. Before starting the actual installation of the valve, determine the proper installation orientation of the V‐notch ball
(key 2) and actuator. Determine the flow direction of the process fluid through the valve. See figure 2.

1. Use instead of cap screws.
Note
For control valves used in slurry service, mount the actuator and install the control valve so that the V‐notch ball rotates above the
valve drive shaft (refer to figure 2), if possible.
5. Before installing the valve, make sure the flow direction arrow (key 32) on the valve (key 1) matches the actual
process fluid flow direction through the valve for the application where the valve will be installed.
Note
For best shutoff performance, install the valve with the drive shaft horizontal and the Vee‐Ball closing in the downward direction
for standard right hand mounting.

6. Install the flange gaskets and insert the valve between the mating pipeline flanges. Use flat sheet gaskets
compatible with the process media, or spiral wound gaskets with compression‐controlling center rings.
7. Install the line bolts and nuts; then, tighten them using accepted bolting procedures. These procedures include, but
are not limited to, lubricating the line bolts and hex nuts and tightening the nuts in a crisscross sequence to ensure
proper gasket load.
8. If a purge is desired for the purged bearing construction, remove the pipe plugs (keys 29 and 24) and install the
purge lines. Purge pressure should be greater than the pressure within the valve and the purge fluid should be as
clean as possible.
WARNING
A CV500 drive shaft is not necessarily grounded when installed in a pipeline unless the shaft is electrically bonded to the
valve.
To avoid personal injury or property damage resulting from the effects of a static electricity discharge from valve
components in a hazardous atmosphere or where the process fluid is combustible, electrically bond the drive shaft (key 3)
to the valve according to the following step.
Note
Standard CV500 packings (key 13) are composed either entirely of conductive packing rings (graphite ribbon packing) or partially
of conductive packing rings (a carbon‐filled PTFE female adaptor with PTFE V‐ring packing or a graphited‐composition packing ring
with PTFE/composition packing) in order to electrically bond the shaft to the valve body. Alternate shaft‐to‐valve body bonding is
available for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve (see the following
step).
9. For hazardous applications, attach the bonding strap assembly (key 131, figure 3) to the shaft with the clamp (key
130, figure 3) and connect the other end of bonding strap assembly to the valve body with the cap screw (key 25,
figure 3).
10. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When a manual actuator
(handwheel) is used with a power actuator, install a bypass valve on the power actuator (if not already supplied) for
use during manual operation.

WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.
If the valve has ENVIRO‐SEAL™live‐loaded packing installed, readjustment will probably not be required. See the
instruction manual titled Fisher ENVIRO‐SEAL Packing System for Rotary Valves (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 near the end of this manual.
Maintenance
WARNING
Avoid personal injury or 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 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 and relieve any actuator spring precompression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations.
D The valve packing area 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.
Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection
and replacement depends upon the severity of service conditions.
Packing Maintenance
Key numbers refer to figure 9 for NPS 3 through 8 and to figure 10 for NPS 10 and 12 unless otherwise indicated.
Note
For the ENVIRO‐SEAL packing system, refer to the Parts List section for retrofit kits, parts kits, and individual parts (see figures 11
and 12). Refer to separate ENVIRO‐SEAL instruction manual (D101643X012) for maintenance instructions.
Standard ENVIRO‐SEAL packing systems can be used in vacuum service with packing rings in the standard orientation. It is not
necessary to reverse the ENVIRO‐SEAL PTFE packing rings.

Instruction Manual
D101640X012
CV500 Valve

Stopping Leakage
All maintenance procedures in this section may be performed with the valve body (key 1) in the line.
For packings other than spring‐loaded packing, leakage around the packing follower (key 14) may be stopped by
tightening the packing flange nuts (key 16). If leakage cannot be stopped in this manner, replace the packing
according to the Replacing Packing procedure in this manual.
If the packing is relatively new and tight on the drive shaft (key 3), and if tightening the packing nuts does not stop
leakage, it is possible that the shaft is worn or nicked so that a seal cannot be made. If the leakage comes from the
outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches on the packing box wall.
Inspect the shaft and packing box wall for nicks or scratches when performing the following procedures.
Replacing Packing
Note
If the valve has ENVIRO‐SEAL live‐loaded packing installed, see the manual entitled Fisher ENVIRO‐SEAL Packing System for Rotary
Valves (D101643X012).
This procedure may be performed without removing the actuator from the valve if adding PTFE/composition packing
rings as a temporary measure. However, the actuator must be removed if replacing any other kind of packing or if the
metal packing parts (keys 14, 17, and, if used, 18) need to be replaced.
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the
process media from both sides of the valve. If using a power actuator, also shut‐off all pressure lines to the power
actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in
effect while you work on the equipment.
CAUTION
To avoid increased leakage, increased valve component wear or possible damage to the valve body, ball, shaft, and
bearings resulting from a sharp blow to the shaft, use a wheel puller to separate the actuator parts from the drive shaft.
Do not drive the actuator parts off the drive shaft since this could move the valve bearings, shaft, and ball away from
proper alignment, causing improper seating of the ball. Such misalignment may result in damage to valve components if
the valve is returned to service without disassembly and inspection of the valve ball alignment.
2. If necessary, remove the cap screws (key 25) and hex nuts (key 26). Then remove the actuator while referring to the
actuator instruction manual for assistance.
3. Remove the packing nuts (key 16). For NPS 3 through 8, remove the packing follower (key 14). For NPS 10 and 12,
remove the packing flange (key 45) and then remove the packing follower (key 14).
CAUTION
In the following step, take care not to scratch the valve shaft or packing box wall, as this may cause leakage.

Instruction Manual
D101640X012
CV500 Valve
June 2017

4. Remove the old packing rings (key 13), packing box ring (key 17), and, if used, the lantern ring (key 18). Do not
scratch the valve shaft or packing box wall; scratching these surfaces could cause leakage. Clean all accessible metal
parts and surfaces to remove particles that would prevent the packing from sealing.
5. Whenever you are installing new packing, be sure the ball (key 2) is closed while you install and tighten the new
packing. Install the new packing rings and packing box ring by stacking the parts as shown in figure 4. Make sure
split rings are arranged so that the splits do not line up to form a leak path. Then slide the stack into the packing box
as far as they will go while being careful to avoid trapping air among the rings.
6. Install the packing follower (key 14), and, for NPS 10 and 12, also install the packing flange (key 45). Install the nuts
(key 16), and tighten them far enough to stop leakage under normal conditions.
7. Mount the actuator while referring to the actuator mounting procedures in the actuator instruction manual.
Complete the Adjusting Actuator Travel procedure in this manual before installing the valve in the pipeline. This is
necessary due to the measurements that must be made during the actuator adjustment process.
8. When the control valve is being put back into operation, check the packing follower for leakage, and retighten the
packing nuts as necessary.
Replacing Retainer, Seat Ring, and Face Seals
This procedure is to be performed if the control valve is not shutting off properly, if installing a different seat ring, or if
seat ring inspection is necessary. The actuator and valve must be removed from the pipeline; however, the actuator
may remain mounted during this procedure. Key numbers refer to figure 9 for NPS 3 through 8 and to figure 10 for
NPS 10 and 12 unless otherwise indicated.
A retainer tool is required to remove the retainer (key 5). If specifically ordered, a tool is supplied with the valve; a tool
can also be ordered individually by referencing key 33 of the Parts List. If desired, a tool can be machined using the
dimensions shown in figure 5.
CAUTION
During assembly, handle the retainer, seat ring, and face seals carefully. Critical areas that must be protected are the
threads and inner surface of the retainer (key 5), the sealing surfaces of the face seals (key 8), the face seal grooves in the
seat ring (key 4), the shutoff surface of the seat ring, and the face seal surface in the valve body.
A new retainer gasket (key 11) is required whenever the retainer (key 5) is removed. Other parts that are in good
condition can be reused.
