Introduction
Scope of Manual
This instruction manual includes installation and parts information for Fisher ENVIRO‐SEAL live‐loaded packing
systems (see figure 1). These systems are available for Fisher rotary valves with 12.7 through 88.9 mm (1/2 through
3‐1/2 inch) shaft diameters. The system can be used with many rotary valves, as shown in tables 1 and 3. Refer to
appropriate valve and actuator instruction manuals for necessary information relating to the disassembly and
assembly of the valve and actuator. ENVIRO‐SEAL packing systems utilize a Belleville (coned‐disk) spring system.
Do not install, operate, or maintain the ENVIRO‐SEAL packing system, valve, actuator or accessories 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 have any questions about these instructions, contact your Emerson
sales office before proceeding.

Valve/Actuator Shaft Coupler
To install an ENVIRO‐SEAL packing system on an A11, A31A, A31D, or 8532 valve with a non‐standard, non‐Fisher
produced actuator may require a special valve/actuator shaft coupler.
Table 10 contains a list of valve/actuator combinations and part numbers for the new coupler. If you are considering
installation of an ENVIRO‐SEAL packing system in another existing valve/actuator package, check table 10 to see if a
new coupler is required.
In some cases, coupler replacement is not required when retrofitting valve/actuator combinations. Table 11 contains a
list of valve/actuator combinations that can use existing couplers.
Description
Fisher packing systems are offered with exceptional sealing capabilities that you can easily install in existing valves or
that you can purchase with new valves. These systems help you conserve valuable process fluid. The external
live‐loading provides a constant load over the life of the packing material, which reduces the need for packing box
adjustment and maintenance.
The system design, coupled with very smooth shaft finishes and spring‐loading of the packing, provides longer service
with lower maintenance than many other designs.

Installation
Use these instructions to install ENVIRO‐SEAL packing in valves that have standard packing, or when inspecting or
replacing ENVIRO‐SEAL packing.
If you are changing the packing system material from standard graphite to ENVIRO‐SEAL graphite or ENVIRO‐SEAL
PTFE packing, the packing friction for ENVIRO‐SEAL packing will be lower than it was for the standard packing.
Therefore, no change should be needed in actuator sizing.
If you are changing the packing system material from standard PTFE to ENVIRO‐SEAL graphite or ENVIRO‐SEAL PTFE
packing, the packing friction will increase. Contact your Emerson sales office
be large enough.
WARNING
Always wear protective gloves, clothing and eyewear when performing any maintenance operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given in this manual, the appropriate valve instruction manual,
or the limits on the appropriate name plates. Use pressure relieving devices 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 Removing the Actuator section
in this instruction manual.
to determine if your existing actuator will
Removing the Actuator
WARNING
Avoid personal injury from sudden release of process pressure or uncontrolled movement 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 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 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, 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.

You must remove the actuator from the valve when you install ENVIRO‐SEAL packing systems. To allow proper
readjustment of the valve disk position, it is recommended that you remove the valve from the pipeline. Refer to
appropriate valve and actuator instruction manuals.
WARNING
If a spring‐return actuator is used, be sure the actuator spring is resting on its travel stop. If something is obstructing shaft
rotation, it is possible that disconnecting the shaft connector will allow the spring to force the actuator to the end of its
rotation, resulting in possible personal injury or property damage. Refer to the appropriate valve and actuator instruction
manuals to remove the actuator.
Installing an ENVIRO‐SEAL Packing System
Note
When installing an ENVIRO‐SEAL packing system into an insulated valve, do not cover the packing springs with insulation.
Note
The valve shaft surface condition is critical in obtaining a good seal. If the valve shaft surface is scratched, nicked, or worn, replace
the valve shaft before installing the ENVIRO‐SEAL Packing System.
Refer to the appropriate valve instruction manual to replace the valve shaft.
Key number locations are shown in figures 2 and 4 for Vee‐Ball, eccentric plug, 8560, and A41 valves, and in figures 3
and 5 for A11, A31A, A31D and 8532 valves.
1. If you are installing an ENVIRO‐SEAL packing system in an existing valve, remove existing packing nuts, packing
flange, jam nuts, anti‐blowout flange, packing follower, and any other external packing components from the valve
body.
CAUTION
Because the valve shaft surface condition is critical in obtaining a good seal, caution must be used when removing existing
internal packing parts. Do not scratch, nick or dent the valve shaft.
2. For A11, A31A, A31D and 8532 valves, remove the anti‐blowout wire that surrounds the valve shaft.
3. For all valves, remove packing and all other internal components from the packing box.
4. Inspect the existing valve shaft. If necessary, replace the valve shaft. Refer to the appropriate valve instruction
manual to replace the valve shaft.

a. Place one of the packing box rings (key 107) into the packing box. Be sure the packing box ring is properly seated.
This does not apply to NPS 3, 4 and 6 CL600 A11 valves.
b. For PTFE packing, place an anti‐extrusion washer (key 106) into the packing box and push it in until it rests next
to the packing box ring (key 106 is not used with graphite packing).
Note
The graphite packing set has a carbon anti‐extrusion ring on the top and bottom of the packing. These anti‐extrusion rings are
designed to have a slight interference fit on the shaft. The rings have a single fracture to allow the ring to be installed on the shaft.
Additional fractures may develop while the valve is in service, however, these additional fractures will not affect the performance
of the ENVIRO‐SEAL packing.
c. Place the packing set (key 105) into the packing box. Refer to figure 3 or 5 for the proper orientation of the
packing set.
d. For PTFE packing, place another anti‐extrusion washer (key 106) into the packing box after the packing set (key
106 is not used with graphite packing).
e. Place the second packing box ring (key 107) into the packing box.
f. Locate the new spring pack assembly (key 103). Remove the O‐ring and packing springs from the packing
follower. Use the packing follower to press the packing components into the packing box. Remove the packing
follower.
6. For A11, A31A, A31D and 8532 valves, install the anti‐blowout wire (key 16) in the groove around the valve shaft.
7. Slide the packing follower from the new spring pack assembly over the valve shaft and the anti‐blowout wire until it
rests against the packing box ring.
8. For all valves, install the longer packing studs (key 100).
9. For A11, A31A, A31D and 8532 valves, install the new anti‐blowout flange (key 10) over the valve shaft, packing
studs, and packing follower. Secure the anti‐blowout flange with the new jam nuts (key 17).
10. For all valves, install the spring pack assembly (key 103 or 104) which includes the Belleville springs, packing
follower, and O‐ring arranged as shown in figures 2 through 6. (The O‐ring is a non‐functional part and is used to
retain the packing springs during assembly.)

Note
In general, the following tightening procedure applies to all ENVIRO‐SEAL packing systems—both sliding‐stem and rotary.
CAUTION
Excessive force could cause valve body bushing displacement in Non‐Series B Vee‐Ball valves, allowing Vee‐Ball
misalignment, excessive seat leakage, or stalling of the actuator.
Note
Lubrication is required for the packing studs and nuts. Although it is important to properly lubricate the stud threads and internal
nut threads, it is also important to properly lubricate the contacting face of the nut. See figures 2 through 5 and 7 for lubrication
locations.

Note the following definitions. You will need them for the next few steps. The target load is the point where the
Belleville springs are designed for optimum performance, when they are compressed to 85% of their maximum
deflection, or nearly flat. Maximum deflection is when the springs are 100% compressed, or completely flat.
12. You will obtain maximum benefit from your ENVIRO‐SEAL packing system when you tighten the packing flange
nuts and compress the Belleville springs to their “target load”.
To obtain the target load of 85% compression of maximum deflection, perform the following:
D Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange
(see figure 7), until the Belleville springs are compressed 100% (or completely flat).

CAUTION
Do not use pneumatic air tools. Do not apply torque in excess of 34 NSm (25 ftSlbs) increments to any one flange nut at a
time. Excessive over‐torquing of the flange nuts may cause the studs to break.
D For PTFE packing, loosen each packing flange nut 1/2 turn (180_ of rotation).
D For graphite packing, loosen each packing flange nut 1/4 turn (90_ of rotation).
The “target load” of 85% compression has now been reached.
13. Install the actuator. Refer to the appropriate valve and actuator instruction manuals when connecting the valve to
the actuator.
Under normal conditions, the packing nuts should not require re‐tightening.
However, when servicing, if the springs do not remain at the target load of 85% compression, retighten the packing
box nuts according to step 11 above.

Other Considerations
ENVIRO-SEAL System - Rotary Valves
February 2019
Note
The following check is only valid for rotary ENVIRO‐SEAL packing systems and sliding‐stem ENVIRO‐SEAL or HIGH‐SEAL packing
systems.
When retrofitting an existing packing system or repacking a valve with ENVIRO‐SEAL packing that has been in service,
check the condition of the packing bore after you have removed the packing. An easy method for cleaning debris and
minor imperfections from the bore is to use a brake cylinder hone attached to an electric drill. This method will do a
good job of cleaning the packing bore without changing the dimension of the bore.
When you have completed this exercise, a good guideline to use in checking the condition of the packing bore is the
20/20 rule. If less than 20% of the surface area of the bore is pitted and if no pits are deeper than 0.020 inch, then your
packing will work fine. This does not need to be an exact measurement; visual inspection is adequate. If the packing
bore does not meet this criteria, however, you should replace the valve or have your Emerson service center repair it.

ENVIRO-SEAL System - Rotary Valves
February 2019
Parts Ordering
Each valve assembly is assigned a serial number that can be found on the valve body. Refer to the serial number when
contacting your Emerson sales office
When ordering replacement parts, refer to the serial number and to the 11‐character kit number for each kit required
from the following list. Kits for valves with shaft sizes greater than 38.4 mm (1‐1/2 inch) will not be available, however,
ENVIRO‐SEAL parts may be ordered separately. Consult your Emerson sales office for details.
for technical assistance.
Parts Kits
Retrofit Kits
Retrofit kits include all parts required for installation of the ENVIRO‐SEAL packing system into existing rotary and high
performance butterfly valves. Retrofit kits are available for single PTFE or graphite packing. See tables 5 through 7 for
retrofit kit part numbers.
The 8510B has two packing boxes, one at the actuator end and one at the outboard end. Select a kit from each column
of the following table.
Packing boxes in V500 and CV500 valve bodies may be deep drilled, (at one time standard on all CV500 and always
available as an option). If the valve body being retrofitted has a deep packing box, use the longer packing box ring (key
107) from the original packing. Discard the 3 mm (1/8‐inch) packing box ring from the retrofit kit. If a replacement
packing box ring (long, key 107) is required, refer to the valve instruction manual for parts, or consult your Emerson
sales office. Refer to figure 2, the view titled: Double PTFE Packing with Leakoff—Optional Deep Packing Box.
Note
1. Use the existing long packing box ring (key 107) that was furnished with the original valve when installing the retrofit kit in:
•V200 NPS 8 and 10 valves, or
•V150 and V300 NPS 8, 10, and 12 valves
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
