Fisherr657 and 667 Diaphragm Actuators
Fisher 657 and 667 spring-opposed diaphragm
actuators position the valve plug in the valve in
response to varying controller or valve positioner
pneumatic output signals applied to the actuator
diaphragm. Zero setting of the actuator is determined
by the compression of the actuator spring. Span is set
by both the actuator spring rate and the number of
springs available. The 657 actuator is direct-acting; the
667 is reverse-acting. These actuators are designed to
provide dependable on-off or throttling operation of
automatic control valves.
Features
Application Versatility–Five actuator types in eleven
sizes are available for an extensive variety of
applications. Spring rates, travel stops, and manual
operators are available for nearly any control valve
application.
Excellent Linearity Between Loading Pressure and
Travel–A molded diaphragm travels in a deep
diaphragm casing, minimizing area change
throughout the travel.
High Degree of Dynamic Stability and Frequency
Response–A shallow casing on the pressure side
means reduced volume on that side, thereby
minimizing response time.
High Thrust Capability–The molded diaphragm
allows maximum thrust for given diaphragm size.
Long Service Life–Rugged thick-walled cast iron and
steel construction provides increased stability,
corrosion protection, and protection from
deformation should over-pressurization occur.

Cold Service Applications–Enhanced product
specifications for all sizes of 657 and 667 diaphragm
actuators allow performance to -50_C(-58_F). Use
of a positioner is recommended to ensure
responsiveness in applications operating below
-40_C(-40_F).
Positive Connections–A split block stem connection
provides a solid transfer of motion while allowing
easy mounting. The absence of linkages helps to
avoid lost motion and inaccurate valve positioning.

Available Configurations
Direct Action
All 657 actuators are direct acting. Applying air
pressure to the upper diaphragm casing forces the
actuator stem downward. When this pressure is
reduced, the opposing spring force moves the
actuator stem upward. Should the loading pressure
fail, the spring forces the stem to the extreme upward
position. This provides fail-open action for
push-down-to-close valves and fail-closed action for
push-down-to-open valves.
657–Adirect-acting actuator used on sliding-stem
valves. Available in sizes 30 through 100. See figures 1,
2, 5, and 6.
657-4–A 657 actuator in sizes 70 and 87, designed
with 102 mm (4-inch) travel.
Reverse Action
All 667 actuators are reverse acting. Applying air
pressure to the lower diaphragm casing forces the
actuator stem upward against the opposing spring
force. When this loading pressure is reduced, the
spring moves the actuator stem downward. Should
the loading pressure fail, the spring forces the stem to
the extreme downward position. These actuators
provide fail-closed action for push-down-to-close
valves and fail-open action for push-down-to-open
valves.
667–A reverse-acting actuator used on sliding-stem
valves. Available in sizes 30 through 100 and 76. See
figures1,2,and7.
667-4–A 667 actuator in sizes 70 and 87, designed
with 102 mm (4-inch) travel.
Accessories
Handwheels
Handwheels for diaphragm actuators are often used as
adjustable travel stops. They also provide a ready
means of positioning the control valve in an
emergency. The specifications in tables 5 and 6 apply
to handwheels on both 657 and 667 Series actuators.
For repeated or daily manual operation, the unit
should be equipped with a side-mounted handwheel
actuator.
Top-Mounted Handwheels–Typical 657 and 667
actuators with handwheels mounted on the
diaphragm case are shown in figure 2 (not available on
a 667 actuator, size 80). On the 657 actuator, the
handwheel can be set to limit the travel in the upward
direction; on the 667 actuator, travel in the downward
direction can be restricted. A P-2 travel stop (figure 4)
is available for a 667 actuator, sizes 45-60 to limit
travel in either the upward ordownwarddirections.An
actuator with a P-2 travel stop is limited to a maximum
travel of 19 mm (0.75 inch). The handwheel on the size
100 is similar in function to those on the smaller sizes,
but it uses a gear drive similar to the drive employed
on the integral side-mounted handwheels (see figure
2).

1. For Size 76 667 actuators, contact your Emerson Process Management sales office.
2. Consult Fisher 657 and 667 instruction manuals (D100306X012, D100307X012,
D100310X012, and D100311X012) for additional information on maximum pressure
limitations.
Clockwise rotation of the handwheel on the 657
actuator moves the actuator stem downward,
compressing the spring. Spring action returns the
stem as the handwheel is turned counterclockwise.
With the 667 actuator, counterclockwise rotation
moves the stem upward, and spring action returns the
stem on clockwise rotation.
Side-Mounted Handwheels–Figure 3 shows the
side-mounted handwheels (designated by the letters
MO) applicable to sizes 34 through 87, 657 and 667
actuators. Size 30 actuators do not have a
side-mounted handwheel available.
All side-mounted handwheels can be used to stroke
the valve in either direction at any point in the actuator
stem travel. Unlike the top-mounted handwheel, the
side-mounted handwheel can be positioned to limit
travel in either direction, but not both at the same
time. With the handwheel in the neutral position,
automatic operation is possible throughout full valve
travel. In any other position, valve travel will be
restricted. The handwheel is furnished with a
spring-loaded ball detent which prevents vibration
from changing the setting.
Adjustable Travel Stops
Top-mounted adjustable travel stops are available for
657 and 667 Series actuators. They are used to limit
travel in the up, down, or up and down directions.
Figure 4 illustrates the different constructions. Table 7
locates the different style constructions with actuator
type and use.
Other
Accessories such as transducers, positioners, position
transmitters, air relays, volume boosters, switching
valves, lockup valves, limit switches, and solenoid
valves are also available for actuator mounting. They
are described in separate publications. Contact your
Emerson Process Management sales office for details.
