Description
The 8510B flangeless control valve has an eccentrically mounted disc that self-centers in the line during installation.
The valve includes built-in electrical bonding of the shaft to the valve body. This valve has either a splined shaft for use
with power, handwheel, or handlever rotary actuators, or a double D end connection with anti-blowout shaft for use
with 1035 Rack and Pinion actuators and other quarter-turn actuators. It is used for throttling or on/off control of a
wide variety of liquids and gases. The 8510B is a balanced construction available in CL150 through 600. Figure 8
illustrates the various constructions.
Specifications
Specifications for the 8510B valve body are shown in table 1.
Installation
Key numbers in this procedure are shown in figure 8 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 c ertain the service
conditions do not exceed either the valve body rating or the flange joint rating, or other limits given in table 1 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 in this
instruction 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

The maximum allowable inlet pressures for steel, stainless steel, alloy 20, and M35-1 valve bodies are consistent with
the pressure-temperature ratings shown in table 2, except where further limited by the trim and packing material
temperature capabilities given 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 that it is free of foreign material.
3. The valve is normally shipped as part of a control valve assembly, with a power or manual 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 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
4
Instruction Manual
D251400X012
8510B Valve (EMA)

section of this manual and to the separate actuator instruction manual for mounting and adjusting instructions before
proceeding.
4. Be certain that adjacent pipelines 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 disc (key 3) will occur if any pipe flanges or piping connected to the valve body interfere with the disc
rotation path. However, the disc 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 DIN or JIS
pipe sizes. If piping with a smaller inner diameter than specified above is connected to the valve, measure carefully to be
certain the disc rotates without interference before putting the valve into operation.
5. Flow is in the standard direction when the seal retainer (key 2) is facing upstream. Standard flow direction is also
indicated by the flow direction arrow cast into the valve body. Flow in the reverse direction is permissible.
CAUTION
Rotating the disc (key 3) past either t he open or closed position could damage the seal and disc sealing surfaces and could
cause the disc to jam in the valve body bore. The disc stop should be zeroed in its flat position as shown in figure 7. Do not
use the disc stop as a travel stop for the actuator. Use the actuator travel stop provisions.
6. With the disc 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. Composition
gaskets may be used to 343_C (650_F), and the optional FGM gaskets (key 29, not shown) may be used for —129 to
538_C (—200 to 1000_F) temperatures.
7. There are four flange bolt holes in the valve body (key 1), and each hole engages one corresponding line flange
stud. Insert the valve between the flanges and i nstall the four line flange studs to roughly center the valve body in
the pipeline.
8. After centering the valve body, first lubricate and then install the remaining line flange studs to secure the valve in
the pipeline. Tighten the nuts to the line flange studs in a crisscross sequence to ensure proper alignment of the
valve body with the flanges.

Instruction Manual
D251400X012
WARNING
An 8510B 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 that the valve body is grounded to the
pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.
Note
Standard 8510B packings 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 or a graphite composition packing ring with
PTFE/composition 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 131, figure 2) to the shaft with the clamp
(key 130, figure 2), and connect the other end of the bonding strap assembly to the valve body with the cap screw
(key 22). Secure each cap screw with a hex nut (key 30).
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.
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 near the end
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 packing; replacing disc, shaft, or bearing(s); changing disc 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) or manual actuators (such as handwheel or handlever 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.
6
Instruction Manual
D251400X012
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 spring precompression.
D Uselock-outprocedurestobesurethattheabovemeasures s tay 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 from 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.
8510B Valve (EMA)

Packing Maintenance
Key numbers are referenced in figure 3 unless otherwise indicated. All maintenance operations in this section may be
performed with the valve in the line. Packing may be PTFE V-ring or graphite.
An ENVIRO-SEAL packing system is also available with the 8510B control valve. To install the ENVIRO-SEAL packing
system in an existing valve, follow the instructions in the instruction manual included with the packing system
(D101643X012). To remove packing parts in a valve with the ENVIRO-SEAL packing system, follow the procedures for
valves with the ENVIRO-SEAL packing system in this section. Install the replacement packing following the instructions
in the packing system instruction manual (D101643X012).
Stopping Leakage
For valves with PTFE or graphite packing:
CAUTION
Tighten the packing flange only enough to prevent shaft leakage. Excessive tightening will only accelerate wear of the
packing and could produce higher torques on the valve.
Leakage around the packing followers can be stopped by tightening the packing flange nuts (key 12, figure 8).
If the packing is relatively new and tight on the shaft, and if tightening the packing flange nuts does not stop leakage,
the shaft may be worn or nicked so that a seal cannot be made. If the leakage comes from the outside diameter of the
packing, the leakage may be caused by nicks or scratches around the packing box wall. Inspect the shaft and packing
box wall for nicks and scratches when performing the packing replacement procedures.
For valves with the ENVIRO-SEAL packing system:
Optimum performance of the ENVIRO-SEAL packing system is obtained when the Belleville springs are tightened to
their “target load.” The target load is the point where the springs are compressed to 85% of their maximum deflection,
or nearly flat. Maximum deflection is when the springs are 100% compressed, or completely flat.
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 the following
procedure:
1. Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange
(see figure 3), until the Belleville springs are compressed 100% (or completely flat).
7
8510B Valve (EMA)
November 2011
Instruction Manual
D251400X012
D For PTFE packing, loosen each packing flange nut one half turn (180_ of rotation).
D For Graphite packing, loosen each packing flange nut one quarter turn (90_ of rotation).
The target load of 85% compression has now been reached. If leakage continues, replace the packing components as
described in the following procedures.
Replacing the Packing
For valves with PTFE or graphite packing:
This procedure may be performed without removing the actuator from the valve body if adding split
PTFE/composition packing rings as a temporary measure on the actuator side of the valve body. However, the actuator
must be removed from the valve body if replacing any other kind of packing on the actuator side of the valve body.
Key numbers in this procedure are shown in figure 8 unless otherwise indicated.
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 shutoff 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.
2. Remove the packing flange nuts (key 12) and packing follower (key 15), plus the packing flange (key 9) if used, from
thesideofthevalvebodyoppositetheactuator.
CAUTION
If removing the actuator in the following step, use a wheel puller to separate the actuator parts from the valve shaft. Do not
drive the actuator parts off the valve shaft because this could move the valve bearings and disc away from the centered
position, thereby damaging the disc and the valve body.
3. If necessary to remove the actuator, remove the cap screws and nuts (keys 22 and 30). Remove the clamp (key 130,
figure 2) if the strap (key 131, figure 2) is used. If necessary, refer to separate actuator instruction manuals for
assistance in removing the actuator.
4. Remove the packing flange nuts and pull out the packing follower (key 16), plus the packing flange (key 10) if used,
fromtheactuatorsideofthevalvebody.
5. Remove the old packing rings (key 13) and, if used, the packing washers (key 27). Carefully avoid scratching the
shaft or packing box wall to avoid damage that could cause leakage around the shaft. Clean all accessible metal
parts and surfaces to remove particles that would prevent the packing from sealing.
