Valve Body
Design 461
May 1981 Form 5170
This instruction manual provides installation, maintenance, and parts ordering
information for the Design 461 anti-coke valve body. Information regarding
actuators and other accessories can be found in separate instruction manuals.
Description
The Design 461 is a self-cleaning, increased-outlet, angle-style valve body.
It is specifically designed to control the flow of erosive or sticky fluids
while preventing particle build-up on internal valve parts. It is used in
both throttling and on-off applications. Because of its venturi-type outlet,
the Design 461 valve body is often chosen for applications where flashing is a
problem.
INSTALLATION
WARNING
To avoid personal injury or equipment damage caused
by sudden release of pressure, install the valve
assembly only where service conditions will not
exceed the limits given on the appropriate nameplate.
1. Before installing a Design 461 valve body, inspect it for any foreign
material that may have collected during crating or shipping.
2. Check that the pipelines are free of pipe scale, chips, welding slag, and
other foreign material.

I Design 461
3. Use accepted piping practices when installing the valve.
4. Do not install the valve in a system where the service conditions exceed
those specified when the valve was ordered.
5. If continuous operation is required during maintenance and inspection,
install a three-valve bypass around the body so that it will be isolated.
6. Orient the body so that the flow will be in the direction indicated by
the flow direction arrow located on the outside of the valve body to
ensure proper self-cleaning action.
7. If the actuator and valve are shipped separately, refer to the actuator
mounting procedure outlined in the appropriate actuator instruction
manual.
MAINTENANCE
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.
Replacing Packing
WARNING
To avoid personal injury and equipment damage, isolate
the control valve from the system, and release all
pressure from the body and actuator before starting
maintenance operations.
Refer to figure 1 unless otherwise indicated.
1. Turn the spring adjustor to release all spring compression in the actuator.
2. Disconnect the operating lines from the actuator. Disconnect the stem
connector, and then remove the actuator from the valve.
3. Remove the hex nuts (key 8, figure 2) from the bonnet flange, and loosen
the packing flange nuts (key 25) so that the packing is not tight on the
valve stem.
4. Lift the bonnet (key 14) off the valve stem (key 10, figure 2). If the
valve plug and stem assembly starts to lift with the bonnet, tap it back
down using a brass or lead haoxner on the end of the stem. Set the bonnet
on a cardboard or wooden surface to prevent damage to the bonnet gasket
surface.
5. Remove the packing flange nuts (key 25), packing flange (key 23), and
packing follower (key 29) from the bonnet (key 14).

Design 461
Pull out the packing rings (key 19), male adaptor (key Zl), and spring
(key 17) with a packing hook (take care to avoid scratching the packing
box wall), or push them out using a rod inserted through the bottom of
the bonnet.
Clean the packing box and all metal parts.
Inspect the valve stem threads for any sharp edges that might cut the
packing. Use a wheatstone or emery cloth to smooth the threads if
necessary.
Install a new gasket (key 6, figure 2). Slide the bonnet over the stem
and onto the stud bolts (key 7, figure 2).
10. Replace packing parts in the order indicated in figure 1. Avoid scratch-
ing the packing box walls. Install the hex nuts (key 8, figure 2) on the
bolts (key 7, figure 2), and tighten in a range from 350 to 400 foot-pounds
(474 to 542 newton-meters), using lubrication such as Never-See2 Nickel
Special* or an equivalent on the bolts.
11. Replace the packing flange (key 23) and packing flange nuts (key 25), and
lubricate the bolts. Tighten the nuts to 37 foot-pounds (50 newton-meters)
to deaerate packing;
(34 newtonmeters).
then loosen the nuts, and tighten to 25 foot-pounds
12. Mount the actuator on the bonnet (key 14), and make up the stem connection
according to the procedure given in the appropriate actuator instruction
manual.
Replacing Trim
Refer to figure 2 unless otherwise indicated.
1. Remove the actuator and the bonnet according to steps 1 through 4 of the
Replacing Packing section.
2. Remove the valve plug and stem assembly (keys 3 and 10) from the valve.
If the stem needs to be replaced, drive the groove pin (key 11) out, and
unscrew the stem from the plug.
CAUTION
Never use an old stem with a new valve plug. The use
of an old stem requires drilling a new groove pin
hole through the stem, which will weaken the stem.

3. If the valve plug needs replacing, replace the entire valve plug and stem
assembly. Do not reuse the old stem on a new valve plug. If only a new
stem is necessary, screw the plug onto the new stem. Drill a 3/16-inch
(4.8 mm) hole through the stem using the plug pin hole as a guide. Drive
the pin into the stem and plug.
4. With the stem and valve plug assembly removed, slide the liner (key 5)
out of the valve body. Inspect the seat ring (key Z).for nicks and
scratches.
5. To replace the seat ring (key 2), remove the valve from the line, or
remove the pipe connected to the lower flange. Then, unscrew the seat
ring retainer (key 4), and remove the seat ring through the bottom of the
valve body. Make sure the valve plug and seat ring contact surfaces are
free of nicks and scratches.
6. To remove the liner (key 5), break it loose by using the cap screws in
the tapped holes located in the liner's flange. (In some very hard
materials, i.e., Alloy 6, the holes have been omitted; therefore, a
sleeve puller or similar device must be used.),
Assembly
---_
1. When assembly, use a new bonnet gasket (key 6), and wipe all sealing
surfaces (body, bonnet, and gaskets) with a clean cloth. If the seat
ring (key 2) was removed, install it in the valve body (key l), and then
screw the seat ring retainer (key 4) in the valve body. Since there is
no gasket between the seat ring and the valve body, make sure that the
mating surfaces are clean and free of nicks and scratches.
2. Replace the liner (key 5), and tighten securely. Then, slide the valve
plug and stem assembly (keys 3 and 10) into the body (key 1).
3. Mount the bonnet (key 14, figure 1) onto the valve body (key 1).
Note
If the seating surfaces of the valve plug and seat
ring require lapping, refer to the Lapping Seating
Surfaces section before continuing to assemble the
valve.
4. If it is necessary to replace the packing, perform steps 5 through 8 of
the Replacing Packing section. However, if it is not necessary to
replace the packing, make sure to install the bonnet carefully on the
valve body to avoid damaging the packing with the valve stem threads.
-4-

I Design 461
5. Lubricate the body stud bolts (key 7) with Never-Seez* lubricant or
equivalent, and install the nuts (key 8) on the bolts. Tighten the nuts
in a range from 350 to 400 foot-pounds (474 to 542 newton-meters) in a
crisscross pattern to ensure a positive seal and even pressure on the
bonnet.
Note
It may be necessary to repeat the bolting pattern
several times until the bonnet-to-body seal is made
since the tightening of one nut might loosen an
adjacent nut. It is recommended that the pattern be
repeated until none of the nuts will turn at the
recommended torque.
6. Mount the actuator on the bonnet, and make up the stem connection
according to the procedure given in the appropriate actuator instruction
manual.
Lapping Seating Surfaces
A certain amount of leakage should be expected with metal-to-metal seating in
any valve body. If the leakage becomes excessive, however, the condition of
the seating surfaces of the valve plug and seat ring can be improved by grinding.
Large nicks should be machined out rather than ground out. Use a conunercial
lapping compound or a mixture of 600-grit Carborundum and solidified vegetable
oil. Apply the compound to the bottom of the valve plug, and apply white lead
to the seat ring to prevent excessive tearing or cutting during lapping. The
white lead should not be mixed with the grinding compound, but rather applied
separately.
The valve must be assembled to the extent that the valve plug and stem assembly
(keys 3 and 10) and the seat ring (key 2) are in place and the bonnet (key 14)
is bolted to the body (key 1). A simple handle can be made from a piece of
strap iron locked to the valve plug stem with nuts. Rotate the handle alternately
in each direction to lap the seats. After lapping, remove the bonnet, and
clean the seating surfaces.
Completely assemble as described in the Assembly
part of the Haintenace section, and test the valve for shutoff. Repeat the
lapping procedure if leakage is still excessive.
