INTRODUCTION
Scope of Manual
This instruction manual provides information on installa-
tion, adjustment, maintenance, and parts ordering for the
Type 657 actuator in sizes 30 through 70 and size 87 and
for the Type 657-4 actuator in sizes 70 and 87. Information
for other equipment used with these actuators is found in
separate manuals.
Description
The Type 657 actuator (figure 1) and the Type 657-4
actuator are direct-acting, spring-opposed diaphragm
actuators used for automatic operation of control valves.
The Type 657 actuator provides up to 3 inches (76 mm)
maximum actuator travel while the Type 657-4 actuator
provides 4 inches (102 mm) maximum actuator travel. Both
actuators position the valve plug in response to varying
pneumatic loading pressure on the diaphragm. Figure 2
schematically shows the operation of these actuators.
Additionally, a Type 657 or 657-4 actuator can be furnished
with either a top-mounted or side-mounted handwheel
assembly. A top-mounted handwheel assembly is usually
used as an adjustable up travel stop. A side-mounted
handwheel assembly is usually used as an auxiliary manual
actuator.
Specifications
Specifications for the Type 657 and 657-4 actuators are
shown in table 1 . Information for a specific actuator is also
found on the nameplate (figure 3) of that actuator.

INSTALLATION
When an actuator and valve body are shipped together, the
actuator is normally mounted on the valve. Follow the valve
body instructions when installing the control valve in the
pipeline. If the actuator is shipped separately or if it is
necesary to mount the actuator on the valve, perform the
"Actuator Mounting" procedures. Refer to figure 4.
Actuator Mounting
1. Screw the stem locknuts all the way onto the valve
stem. Put the travel indicator disc, not used with the size 87
actuator, on the locknuts. The concave side of the disc
should face the valve.

2. For direct-acting valves, push the valve stem down to
close the valve.
For reverse-acting valves, push the valve stem down to
open the valve.
3. Place the actuator on the valve bonnet. For size 30
through 70 actuators, lift or hoist the actuator, if necessary,
in order to slip the yoke locknut over the valve stem.
4. For size 87 actuator, insert the cap screws, and tighten
the hex nuts, securing the actuator to the bonnet.
For all other sizes, screw the yoke locknut tightly onto the
bonnet, securing the actuator to the bonnet.
CAUTION
Do not clamp just the tip of either the valve stem
or the actuator stem in the stem connector.
Incomplete engagement of both valve stem and
actuator stem in the stem connector may result
in stripped threads or improper operation. Be
sure that the length of each stem clamped in
the stem connector is equal to or greater than
the diameter of that stem.
6. Clamp the actuator and valve body stems between the
two stem connector halves. Insert and tighten the two stem
connector cap screws.
7. Raise the travel indicator disc to the stem connector,
and thread the stem locknuts against the stem connector.
Loading Connection
1 . Connect the loading pressure piping to the 1 /4-inch
connection in the top of the diaphragm casing.
2. For size 70 and 87 actuators, remove the 1/4-inch
bushing in the 1/2-inch connection to increase connection
size, if necessary. Either piping or tubing may be used.
3. Keep the length of tubing or piping as short as possible
to avoid transmission lag in the control signal. If an
accessory (such as a volume booster or valve positioner) is
used, be sure that the accessory is properly connected to
the actuator.
4. Cycle the actuator several times to check that the valve
stem travel is correct and that the travel occurs when the
correct pressure range is applied to the diaphragm.
5. If valve stem travel is incorrect, refer to the "Travel"
procedure in the "Adjustments" section.
6. If the pressure range is incorrect, refer to the "Spring"
procedure in the "Adjustments" section.
ADJUSTMENTS
Travel
Make travel adjustments when the motion observed during
actuator travel is different from the travel stamped on the
actuator nameplate (figure 3).
When adjusting travel of a reverse-acting valve, slightly

Type 657
1 . Back the stem locknuts and indicator disc away from
the stem connector, and slightly loosen the stem connector
cap screws.
CAUTION
Do not use wrenches or other tools directly on
the valve stem, or damage to the stem surface
and subsequent damage to the valve packing
may result.
2. Tighten the locknuts together, use a wrench on these
locknuts, and screw the valve stem either into the stem
connector to lengthen travel or out of the stem connector to
shorten travel.
3. Cycle the actuator to check for the specified travel. If
travel is not equal to the specified travel, adjust and check
travel until correct. Tighten the stem connector cap screws
when correct travel is obtained.
4. Raise the travel indicator disc by threading the stem
locknuts against the stem connector.
Spring
Make spring adjustments when the loading pressure range
applied to achieve specified travel is not equal to the
pressure range stamped on the actuator nameplate (figure
3). Refer to the "Bench Set" pressure range on the
nameplate when the valve contains no pressure and the
packing is loosely inserted in the bonnet. Refer to the
"Diaphragm Pressure" range on the nameplate when the
valve is controlling the specified pressure drop and the
packing is tightened to stop leaks around the stem.
1. Monitor loading pressure carefully when making
adjustments. Do not exceed the pressure specifications of
either the loading regulator or the actuator casings.
2. Each actuator spring has a fixed pressure span.
Changing the spring compression shifts the span up or
down to make valve travel coincide with the loading
pressure range.
3. Turn the spring adjustor (key 12, figures 5, 6, and 7)
into the yoke (key 9, figures 5, 6, and 7) to shift the span up
or turn the spring adjustor out of the yoke to shift the span
down.
If the actuator has a side-mounted handwheel assembly
(manual operator), clockwise handwheel rotation closes
the valve.
For successful operation, the actuator stem and valve plug
stem must move freely in response to the loading pressure
change on the diaphragm.
MAINTENANCE
Actuator parts are subject to normal wear and must be
inspected and replaced when necessary. The frequency of
inspection and replacement depends on the severity of
service conditions.
Avoid personal injury or damage to property
from sudden release of pressure or uncon-
trolled process fluid. Before starting to
disassemble:
? Isolate the valve from the process,
? Release process pressure,
? Vent the actuator loading pressure, and
? Relieve all spring compression.
The maintenance instructions are divided into four
sections: "Actuator," "Top-Mounted Handwheel Assembly
(Adjustable Up Travel Stop),? "Side-Mounted Handwheel
Assembly (Manual Operator) for Size 34 through 60
Actuators," and "Side-Mounted Handwheel Assembly
(Manual Operator) for Size 70 and 87 Actuators."
Actuator
This procedure describes how the actuator can be
completely disassembled and assembled. When inspec-
tion or repairs are required, disassemble only those parts
necessaryto accomplish the job; then, startthe assembly at
the appropriate step.
Key numbers refer to figures 5, 6, or 7. Figure 5 illustrates
the size 30 through 60 actuators, figure 6 shows the size 70
actuator, and figure 7 depicts the size 87 actuator.
Disassembly
1 . Bypass the control valve. Reduce the loading pressure
to atmospheric, and remove the tubing or piping from the
top of the diaphragm casing (key 1 ).
2. Thread the spring adjustor (key 1 2) out of the yoke (key
9) until all spring compression is relieved.
3. If necessary, remove the actuator from the valve body
by separating the stem connector (key 26) and removing
the yoke locknut or, for the size 87 actuator, the stud bolt
nuts. Separate the stem connector by loosening the stem
locknuts (keys 15 and 16) and unscrewing the two cap
screws.
4. Remove diaphragm casing cap screws and nuts (keys
22 and 23), and lift off the upper diaphragm casing (key 1 ).

unscrewing it from the yoke.
Assembly
1 . Coat the threads and the spring seat bearing surface of
the spring adjustor (key 1 2) with Lubriplate MAG-1 * or
equivalent lubricant, and thread the spring adjustor into the
yoke (key 9). Place the spring seat (key 1 1) in the yoke on
the spring adjustor.
2. Position the lower diaphragm casing (key 5) on the
yoke (key 9), and fasten the parts together by evenly
tightening the cap screws (key 8).
3. Slide the spring (key 6) squarely onto the lower spring
seat (key 1 1).
4. If the diaphrgam plate and actuator stem (keys 4 and
10) are separate, fasten them together using the cap screw
and washer (keys 3 and 25). Slide the diaphragm rod and
diaphragm plate (keys 10 and 4) into the yoke so that the
spring (key 6) fits squarely between the diaphragm plate
and the spring seat (key 1 1 ). Also, the diaphragm rod (key
10) slides through the spring adjustor (key 12).
5. Place the diaphragm (key 2) pattern side up on the
diaphragm plate (key 4). Align the holes in the diaphragm
and the lower diaphragm casing (key 5).
6. Position the upper diaphragm casing (key 1) on the
diaphragm (key 2) and align the holes.
CAUTION
Over-tightening the diaphragm casing cap
screws and nuts (keys 22 and 23) can damage
the diaphragm. Do not exceed 20 foot-pounds
(27 newton meters) torque.
Top-Mounted Handwheel Assembly
(Adjustable Up Travel Stop)
A top-mounted handwheel assembly is usually used as an
adjustable up travel stop to limit full retraction of the
actuator stem. Turning the handwheel clockwise turns the
handwheel stem (key 133, figures 8 and 9) into the
diaphragm casing and forces the pusher plate assembly
(key 135, figures 8 and 9) against the diaphragm and
diaphragm plate. Instructions are given below for complete
disassembly and assembly. Perform the disassembly only
as far as necessary to accomplish the required main-
tenance; then, begin the assembly at the appropriate step.
The key numbers in this section refer to both figures 8 and 9
unless otherwise specified.
Disassembly
1 . Bypass the control valve. Reduce the loading pressure
to atmospheric, and remove the tubing or piping from the
diaphragm casing (key 1, figures 5, 6, or 7).
2. Turn the spring adjustor (key 12, figures 5, 6, or 7)
counterclockwise to relieve all spring compression.
3. Remove the diaphragm casing cap screws (key 22,
figures 5, 6, or 7), and lift off the upper diaphragm casing
and handwheel assembly.
4. If necessary, the handwheel assembly can be
separated from the diaphragm casing by removing the cap
screws (key 141 ). This may be necessary to replace the 0-

to accomplish the required maintenance; then, begin the
assembly at the appropriate step.
Assembly
1. For a handwheel assembly used on size 30 through
60 actuators, coat the end of the stem (key 133, figure 8)
with Lubriplate MAG-1 or equivalent lubricant. Slide the
pusher plate (key 1 35, figure 8) onto the stem, and drive in
the groove pin (key 140, figure 8) to lock the pieces
together.
For a handwheel assembly used on a size 70 or 87
actuator, pack the thrust bearing (key 1 75, figure 9) with
Lubriplate MAG-1 or equivalent lubricant. Place the thrust
bearing in the pusher plate (key 135, figure 9), slide the two
parts (keys 175 and 135, figure 9) onto the stem (key 133).
Coat the retaining screw threads with Loctite* No. 242 or
equivalent sealant. Insert and tighten the retaining screw
(key 174, figure 9).
2. Coat the 0-ring (key 138) with Lubriplate MAG-1 or
equivalent lubricant, and insert the O-ring in the body (key

3. Coat the threads of the stem (key 1 33) with Lubriplate
MAG-1 or equivalent lubricant. Screw the stem into the
body (key 142).
5. Place the handwheel (key 51 ), the washer (key 1 34),
and hex nut (key 54) on the stem. Tighten the hex nut to
fasten the parts together.
6. If the body (key 142) was separated from the
diaphragm casing (key 1, figures 5, 6, and 7), lubricate the
0-ring (key 139) with Lubriplate MAG-1 or equivalent
lubricant, place the 0-ring in the body, align the holes in the
diaphragm casing and the body, insert the cap screws (key
141), and tighten them evenly following a crisscross
pattern to ensure a proper seal.
Disassembly
1. If desired, the handwheel assembly can be removed
from the actuator yoke. To do this, remove the nuts (keys
147 and 170) from the U-bolts (keys 166 and 143) that hold
the assembly to the yoke.
2. Remove retaining ring (key 154), and drive out lever
pilot pin (key 153).
3. There are two screws (key 1 56) that hold the right and
left hand levers (key 146) together. Remove the screw from
the top of the levers so that the levers will drop down out of
the assembly. Disassemble further, if necessary, by
removing the other screw.
4. Remove screw (key 161) and pointer mounting bolt
(key 159, not shown) located behind pointer (key 160).
5. Remove nut (key 54), lockwasher (key 150), and

Side-Mounted Handwheel Assembly
(Manual Operator) for Size 70 and
87 Actuators
A side-mounted handwheel assembly (figure 1 1) is usually
used as a manual operator. Turning the hand clockwise past
the neutral position always opens the valve. A pair of
sleeves (keys 34 and 46, figure 1 1) opens the valve by
moving the valve stem.
Instructions are given below for complete disassembly
and assembly. Perform the disassembly only as far as
necessary to accomplish the required maintenance; then,
begin the assembly at the appropriate step.
