Figure 1. Type 3024C Actuator with Sliding-Stem Valve
Scope of Manual
Note
This instruction manual provides information on
installation, adjustment, maintenance, and parts
ordering for the Type 3024C actuator (figure 1) for
sizes 30 to 45 and 30E to 45E.
Note
This manual assumes throughout that
the valve construction is
“push-down-to-close.”
Description
The Type 3024C direct acting (extends
stem/air-to-close) actuator (figure 8) and the reverse
acting (retracts stem/air-to-open) actuator (figure 9)
are spring-opposed pneumatic diaphragm actuators
that provide automatic throttling or on-off operation
of sliding-stem control valves.
The actuator will position the valve plug in response
to varying pneumatic loading pressure on the
actuator diaphragm. Figure 2 shows the operation of
D103048X012
Do not install, operate, or maintain a Type 3024C
actuator without first D being fully trained and
qualified in valve, actuator, and accessory
installation, operation and maintenance, and D
carefully reading and understanding the contents of
this manual. If you have any questions about these
instructions contact your Emerson Process
Managementt sales office before proceeding.
Neither Emerson, Emerson Process
Management, nor any of their affiliated
entities assumes responsibility for the
selection, use and maintenance of any
product. Responsibility for the
selection, use, and maintenance of any
product remains with the purchaser

handwheel if required (figure 10). An adjustable up
travel stop can also be fitted (figures 11 and 12).
an ATC (air-to-close) actuator and an ATO
(air-to-open) actuator.
The Type 3024C ATC (air-to-close) actuator springs
are located under the diaphragm plate and they fully
retract the actuator stem for fail action upon loss of
diaphragm casing pressure. The Type 3024C ATO
(air-to-open) actuator springs are located on top of
the diaphragm plate and they fully extend the
actuator stem upon loss of diaphragm casing
pressure. The actuator is mounted on the valve by
means of a cast yoke.

When ordered, the valve configuration
and construction materials were
selected to meet particular pressure,
temperature, pressure drop, and
controlled fluid conditions.
Responsibility for the safety of
process media and the compatibility of
valve materials with the process media
rests solely with the purchaser and
end user. Since some valve body/trim
materials combinations are limited in
their pressure drop and temperature
ranges, do not apply any other
conditions to the valve without first
contacting your Emerson Process
Management sales office.
If installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section in this instruction manual.
Installation
WARNING
Always wear protective gloves,
clothing, and eyewear when
performing any installation operation
to avoid personal injury.
Personal injury or equipment damage
caused by sudden release of pressure
may result if the actuator assembly is
installed where service conditions
could exceed the limits given in tables
1, 2, and 3 or the appropriate
nameplates. To avoid such injury or
damage, provide a relief valve for
overpressure protection as required by
accepted industry and governmental
codes and good engineering practices.
To avoid parts damage, do not use a
normal operating pressure that
exceeds the Maximum Diaphragm
Casing Pressure (see table 1) or
produces a force on the actuator stem
greater than the Maximum Allowable
Output Thrust (see table 2 or 3) or
Maximum Allowable Valve Stem Load.
Check with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
A Type 3024C diaphragm actuator is normally
shipped mounted on a valve. Refer to the
appropriate valve instruction manual when installing
the valve in the pipeline. If the actuator is shipped
separately or if it is necessary to mount the actuator
on the valve, perform the Actuator Mounting
procedure given below. For information on mounting
the positioner refer to the appropriate positioner
instruction manual.
CAUTION
The Type 3024C actuators are
designed to mount on push-downto-close valves. Do not mount these
actuators on any other type of valve
without first contacting your Emerson
Process Management sales office.
Mounting the Actuator on the Valve
The following procedure describes how to mount a
Type 3024C actuator on a push-down-to-close valve
so that the actuator stem and valve stem thread
engagement allows full travel and proper shut-off.
Refer to table 4 and figures 6 and 7 for actuator

between the actuator stem and other
parts of the valve assembly.
Perform one of the following procedures as
appropriate:
For a Type 3024C Air-To-Close Actuator
with a Push-Down-to-Close Valve:
a. Carefully place the actuator on the valve so
that the yoke boss fits over the valve bonnet.
b. Screw the yoke lock nut onto the bonnet and
tighten.
c. Lift the valve plug off the seat by the correct
valve travel for the valve. This is stated on the
nameplate or in table 1.
d. Place the stem connector half (key 50)
approximately halfway between the actuator and
valve stems but observing the F dimension in
table 5 so that any positioner lever (if fitted) is
horizontal at mid-travel. Be sure that the actuator
and valve stem threads are engaging the threads
of the stem connector by at least the distance of
one diameter of the stem.

dimensions. Key numbers referenced in the
following steps are shown in figures 8 and 9.
1. Provide a temporary method of applying
diaphragm air loading pressure to the diaphragm to
move the actuator stem during adjustments.
2. Provide a vice or some other method of
supporting the valve and the weight of the actuator
during assembly.
3. Push the valve stem down until the valve plug is
fully closed.
4. Screw the two stem locknuts (key 52) to the lower
end of the valve stem thread.
WARNING
When moving the actuator stem with
diaphragm loading pressure use
caution to keep hands and tools out of
the actuator stem travel path. Personal
injury and/or property damage is
possible if something is caught
6
CAUTION
Be sure that the length of the actuator
stem and the valve stem in the
connector (key 50) is equal to or
greater than the diameter of that stem.
Incomplete engagement of either the
valve or actuator stem in the stem
connector can result in stripped
threads or improper operation.
In the following procedure do not
rotate the valve plug while it is seated.
This may damage the seating surface
and cause excessive leakage. While
making adjustments, use tools
carefully to avoid damaging the valve
stem. A damaged stem could cut the
packing and allow leakage through the
packing box.
e. Install the other half of the stem connector and
insert the socket screws and nuts and tighten
them.
f. Screw the two stem locknuts (key 52) up the
valve stem to the stem connector and tighten. Do
not over tighten.

g. Slowly decrease and then increase the
diaphragm pressure several times stroking the
valve from the lower end to the upper end of the
spring range.
h. Slowly decrease and then increase the
diaphragm pressure several times stroking the
valve from the lower end to the upper end of the
spring range.
h. Apply air pressure to the diaphragm until the
valve is in the closed position. Loosen the screws
of the travel scale (key 26) and align it with the
indicator on the stem connector.
i. Remove all air pressure from the diaphragm so
that the valve is in its closed position. Loosen the
screws of the travel scale (key 26) and align it
with the indicator on the stem connector.
i. Stroke the valve full travel to ensure that the
travel matches the valve travel on the travel
indicator plate.
j. If the valve travel is not correct, repeat the
stem connector procedure. Remove the air
pressure from the diaphragm, remove the stem
connector and repeat steps c to i.
For a Type 3024C Air-to-Open Actuator
with a Push-Down-to-Close Valve:
a. Apply approximately 0.5 bar pressure above
the upper setting of the spring pressure range to
the bottom of the diaphragm. This positions the
actuator stem (key 8) at the highest point. The
spring range is stated on the nameplate or in
table 3.
b. Carefully place the actuator on the valve so
that the yoke boss fits over the valve bonnet.
c. Screw the yoke lock nut onto the bonnet and
tighten.
j. Stroke the valve full travel to ensure that the
valve travel matches the valve travel on the travel
indicator plate.
k. If the valve travel is not correct repeat the
stem connector procedure. Apply approximately
0.5 bar pressure above the upper setting of the
spring range to the bottom of the diaphragm,
remove the stem connector and then repeat
steps d to j.
Note
When disassembling the stem
connector on Air-to-Open
constructions it is essential to apply
enough air pressure to the underside
of the diaphragm to lift the valve plug
off its seat. This will ensure that all
residual spring compression in the
actuator is supported while the stem
connector is removed.
d. Lift the valve plug off the seat by the correct
travel for the valve. The travel is stated on the
nameplate or in table 1.
e. Place the stem connector half (key 50)
approximately halfway between the actuator and
valve stems but observing the F dimension in
table 5 so that any positioner lever (if fitted) is
horizontal at mid-travel. Be sure that the actuator
and valve stem threads are engaging the threads
of the stem connector by at least the distance of
one diameter of the stem.
f. Install the other half of the stem connector and
insert the socket screws and nuts and tighten
them.
g. Screw the two stem locknuts (key 52) up the
valve stem to the stem connector and tighten. Do
not over tighten.
Actuator Maintenance
Actuator 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 the service conditions.
This section describes how the actuator can be
completely disassembled and assembled. When
inspection or repairs are required, disassemble only
those parts necessary to accomplish the job; then
start to assemble at the appropriate step.
Key numbers refer to figures 8 and 9.

3024C Actuator
WARNING
Avoid personal injury or property
damage from sudden release of
process pressure or bursting of parts.
Before performing any maintenance
operations:
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 from 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.
Disassembly
1. For complete disassembly, the positioner and all
accessories (if attached) must be removed from the
actuator. Follow appropriate removal procedures in
the instruction manuals supplied with the positioner
and accessories.
2. Bypass the control valve. For a top-loaded Type
3024C Air-to-Close actuator reduce the diaphragm
8
air pressure to zero and remove the piping or tubing
from the connection in the upper diaphragm casing
(key 16). For a bottom loaded Type 3024C
Air-to-Open apply air pressure to the diaphragm to
open the valve.
Note
When disassembling the stem
connector on Air-to-Open
constructions it is essential to apply
enough air pressure to the underside
of the diaphragm to lift the valve plug
off its seat. This will ensure that all
residual spring compression in the
actuator is supported while the stem
connector is removed.
3. Undo the stem connector by first slackening the
valve stem locknuts and then removing the socket
bolts.
4. Undo the yoke locknut on the valve bonnet and
carefully lift the actuator off the valve. As you undo
the yoke locknut, ensure that the actuator is properly
supported. If the actuator is a bottom loaded
Air-to-Open type, reduce the diaphragm pressure to
zero and remove the piping or tubing from the
connection in the lower diaphragm casing (key 1).
5. Slightly loosen all diaphragm casing cap screws
(key 19 and 21). Remove the plastic hose (key 22).
Unscrew the short and long diaphragm casing cap
screws and nuts (keys 19, 20 and 21) alternately,
until only the long casing cap screws (key 21)
remain engaged. Then allow the remaining spring
compression to be slowly released by alternately
unscrewing the long casing cap screws.
6. When removing the diaphragm and actuator
springs perform one of the following procedures as
appropriate:
For a Type 3024C Air-to-Open Actuator
(figure 9)
a. Lift off the upper diaphragm casing (key 16),
the casing spacer (key 29) and seal ring (key 30)
if fitted (see figure 13), and remove the springs
(Key 15).
b. Using a strap wrench or soft-jawed vice, hold
the actuator stem (key 8) and remove the travel
stop nut (key14).
c. Remove the diaphragm plate (key 13),
diaphragm (key 11), O-Ring (key 12), pressure
plate (key10) and the split ring halves (key 9).

Assembly
This procedure assumes that the actuator is
completely disassembled. If it is not, start the
instructions at the appropriate step.
1. Before starting assembly, apply lithium grease
(key 200) to the O-ring in the bushing (key 6 and
key 12). Install the new bushing (key 6) and
assemble with the cheese head screws (key 7) onto
the lower diaphragm casing (key 1). Use a torque of
0.4 NSm (3 lbfSin).
c. Remove the pressure plate (key 10), O-ring
(key 12), diaphragm (key 11), diaphragm plate
(key 13) and the split ring halves (key 9).
2. Assemble the ring halves (key 9), pressure plate
(key 10), O-ring (key 12), diaphragm (key 11) and
diaphragm plate (key 13) on to the actuator stem as
shown in figure 9 for Air-to-Open or figure 8 for
Air-to-Close.
7. Carefully slide the actuator stem (key 8) out of
the bottom of the lower diaphragm casing (key 1)
and set it on a protective surface to prevent damage
to the O-ring sealing surface.
3. Apply thread locking adhesive (high strength)
(key 201) to the thread on the upper end of the
actuator stem, fit the travel stop nut (key 14) but do
not tighten. Then perform one of the following
procedures as appropriate.
8. Remove the bellows (key 31), if used.
9. Unscrew the cheese head screws (key 7), then
remove the bushing (key 6).
10. With the actuator disassembled, inspect all parts
for excessive wear and replace as necessary.

d. Lift off the upper diaphragm casing and
remove the springs. Tighten the travel stop nut
(key 14 as follows: Sizes 30, 30E, 34, and 34E,
tighten to 36 NSm (27 lbfSft); Sizes 40, 40E, 45,
and 45E, tighten to 87 NSm 64 lbfSft).
3024C Actuator
CAUTION
Over tightening the diaphragm cap
screws and nuts can damage the
diaphragm. Do not exceed the torque
of 13 NSm (10 lbfSft) for sizes 30, 30E,
34 and 34E and 17 NSm ( 12 lbfSft) for
sizes 40, 40E, 45, and 45E.
Note
e. Replace the spring as previously.
f. For actuator sizes 40E and 45E with 1.5 and 2
inch travels, a casing spacer is fitted between the
upper and lower diaphragm casings. Place the
casing spacer (key 29) on the diaphragm and
then the gasket (key 30) as shown in figure 13.
For a Type 3024C Air-to-Close Actuator
(figure 8)
a. Position the actuator springs symmetrically on
the spring locator (key 17) as shown in figure 5.
b. For actuator sizes 40E and 45E with 1.5 and 2
inch travels, a casing spacer (key 29) is fitted
between the upper and lower diaphragm casings.
Place the gasket (key 30) on the lower casing
and then the casing spacer (key 29) as shown in
figure 14.
c. Carefully slide the actuator stem with the
assembled parts down through the bushing and
position it so that the springs fit correctly over the
seat bosses on the upper side of the diaphragm
plate (key 13). Rotate the diaphragm (key 11)
without moving the diaphragm plate (key 13) so
that the diaphragm holes line with the lower
diaphragm casing holes.
d. Tighten the travel stop nut (key 14) as follows:
Sizes 30, 30E, 34 and 34E tighten to 36 NSm (27
lbfSft); Sizes 40, 40E, 45 and 45E tighten to 87
NSm (64 lbfSft).
4. Install the upper diaphragm casing (key 16) so
that the air connection is located directly above the
air connection in the lower diaphragm casing (key 1).
Using the long cap screws (key 21) and hex nuts
(key 20) first, and then the shorter cap-screws
(key 19) and hex nuts (key 20), bolt the two
diaphragm casings together. Fit the safety plastic
hose (key 22) over the exposed thread of the long
cap-screws (key 21).
Be sure to use the long cap screws
(key 21) first, installing them on
opposite sides of the diaphragm
casing. Tighten them evenly, using a
criss-cross pattern to ensure a proper
seal.
5. Mount the actuator on the valve in accordance
with the Installation Procedures.
Changing the Actuator Action
The actuator can be changed from a Type 3024C
Air-to-Open to a 3024C Air-to-Close action or vice
versa. Remove the pressure plate, diaphragm,
O-ring, diaphragm plate, travel stop nut, springs,
spring locator, self tapping screws and vent
assembly (keys 10, 11, 12, 13, 14, 15, 17, 18
and 23) and reinstall them for the appropriate action.
Follow the instructions in the section on Assembly
on page 8.
Side-Mounted Handwheel
A side-mounted handwheel assembly (figure 10) is
usually used as a manual operator. When mounted
on an Air-to-Close Type 3024C actuator, turning the
handwheel clockwise always closes the valve. When
mounted on an Air-to Open actuator, turning the
handwheel clockwise always opens the valve. A
lever (key 101, figure 10) on the handwheel
assembly opens or closes the valve by moving the
valve stem.
Instructions are given below for complete
disassembly and assembly. Perform the
disassembly only as far as is necessary to
accomplish the required maintenance; then begin
the assembly at the appropriate step.
Refer to figure 10 for key numbers.
Disassembly
1. If desired, the handwheel assembly can be
removed from the actuator yoke. To do this, remove

avoid injury when positioning
components.
2. Loosen the lock (key 115) that secures the drive
screw assembly (key 103).
3. Remove the retaining ring (key 110) and screw
out the drive screw assembly (key 103).
For Sizes 30, 30E, 34, 34E, 40, and 40E
4. Remove the retaining ring (key 108) and drive out
the pivot pin (key 104).
1. Relieve the air pressure on the diaphragm.
Loosen the hex nut (key 25) and turn the adjuster
(key 24) clockwise into the diaphragm case to move
the actuator stem downward or counter-clockwise to
allow the actuator stem to move upward. Since the
valve has push-down-to-close action, full opening
can be restricted. Check the actuator travel and then
tighten the hex nut (key 25).
5. Remove the bushings (key 107) from the body
(key 100).
6. There is a cap screw (key 111), hex nut (key 112)
and spacer (key 105) that hold the two levers (key
101) together. Remove the cap-screw and hex nut
and the two levers can be separated in order to
remove the operating nut (key 102).
Assembly
1. Assemble the operator nut (key 102), the two
levers (key 101) and the spacer (key 105) using the
cap-screw (key 111) and hex nut (key 112).
2. Install the bushings (key 107) in the body
(key 100).
3. Attach the levers (key 101) to the body (key 100)
using the pivot pin (key 104) and the retaining ring
(key 108).
4. Apply lithium grease (key 200) to the drive screw
assembly (key 103) and screw it on to the operating
nut (key 102).
CAUTION
The travel stop hex nut (key 25) has an
elastic stop on its underside to
provide an air seal around the travel
stop thread. It is therefore important,
before slackening this nut, to release
any air pressure on the diaphragm.
5. Install the retaining ring (key 110) to secure the
collar to the body (key 100).
For Sizes 45 and 45E
6. If the handwheel assembly was removed from the
actuator yoke, position the assembly within the yoke
so that the eight mounting holes on the assembly
align with those on the yoke and fit the cap-screws
(key 113) tightening to 28 NSm (20 lbfSft). Should
difficulty be experienced fitting the levers (key 101)
over (for ATC) or under (for ATO) the actuator/valve
stem connector, then partially stroke the
actuator/valve by applying air pressure to the
actuator diaphragm.
The adjustable up travel stop for the sizes 45
and 45E is shown in figure 12. For sizes 45 and 45E,
the adjustable up travel stop cannot be used with a
side mounted handwheel.
Adjustable Travel Stops
The adjustable up travel stop (figures 11 and 12)
limits the actuator stroke in the upward direction
(limits retraction of the actuator stem).
WARNING
When performing the following
adjustment procedures, take care to

1. Remove the screws (key 41) and nuts (key 42)
which hold the protective covers (key 40) to the
actuator yoke and remove the covers.
2. Loosen the machined cheese head screw
(key 37) and turn the adjustment nut (key 38)
clockwise into the bushing (key 36) to increase travel
or counter-clockwise to shorten the actuator travel.
3. Check the actuator travel and then tighten the
machined cheese head screw (key 37).
4. Assemble the protective cover plates (key 40) to
the actuator yoke with the screws (key 41) and nuts
(key 42) taking care to ensure that there is no gap
between the cover plate and the diaphragm casing.
