3024C Actuator
D103051X012
Fisherr 3024C Diaphragm Actuator
The 3024C actuator is a compact spring opposed
pneumatic diaphragm actuator incorporating a cast
yoke mounting and is suitable for general purpose
actuation of globe valves. It will position the valve plug
in response to varying controller or valve positioner
pneumatic output signals applied to the actuator
diaphragm. The 3024C actuator can be assembled as
either direct-acting or reverse-acting and provides
dependable and on-off or throttling operation of
automatic control valves.

Features
Application Versatility–With eight different
configurations available, there is an actuator size to
meet your needs. Multi-spring combinations allow
for accurate selection of actuator thrust and valve
travel.
Reversible Action–The simple design allows the
change of action from direct to reverse acting
without the requirement for extra parts. Change of
action can be easily made in the field.
High Thrust Capability–The moulded diaphragm
and high strength casings allow for a maximum
casing pressure of 6 bar, enabling a high stem thrust
for a given size diaphragm.
Positive Connections–Split block stem connection
provides a solid transfer of motion while allowing
easy mounting and no linkages that create lost
motion or inaccurate valve positioning.

Direct Action
With the direct action mode on the 3024C actuator,
applying air pressure to the upper side of the
diaphragm forces the actuator stem downward while,
atthesametime,compressingthespringsonthe
underside of the diaphragm. Refer to figure 1. When
this pressure is reduced, the opposing spring force
moves the actuator stem upwards. Should the loading
pressure fail, the springs force the stem to the extreme
upward position, thereby providing fail-open action for
apush-down-to-closevalve.
Reverse Action
With the reverse action mode, air is applied on the
underside of the diaphragm while opposing spring
force is on the top side. Increasing air pressure will
force the stem upwards. When the loading pressure is
reduced, the stem moves downwards. Should loading
pressure fail, the springs force the stem to the extreme
downward position, thereby providing fail-closed
action for a push-down-to-close valve.
Accessories
Handwheels
An optional side-mounted handwheel can be fitted to
all sizes of actuator with travel up to 32 mm (1.25 inch)
and where the maximum actuator thrust is less than
14,000 N (3150 lbf). These handwheels provide a
robust method of manually operating the valve in an
emergency o r when there is a loss of instrument air.
Refer to figures 2 and 3 and table 1 for details.
Note, a side-mounted handwheel cannot be fitted on
the sizes 45 and 45E actuator if an adjustable travel
stop is fitted as well.
When mounted on a direct action actuator, turning
the handwheel clockwise always moves the stem
downwards. When mounted on a reverse action
actuator, turning the handwheel clockwise moves the
stem upwards. Disengagement of the handwheel to
enable automatic operation is simply accomplished by
rewinding the handwheel.
Valve Compatibility
With the availability of both metric and imperial
threaded stem connectors, the 3024C can be used
with a range of valve body assemblies such as the
Fisher metric 1018S construction or imperial easy-et
and RSS valve body constructions, along with others.

Adjustable Travel Stops
Top mounted adjustable up travel stops are available
for all actuators from size 30 to 40E. For the larger sizes
45 and 45E, an adjustable stop can be fitted to the
actuator stem below the diaphragm casings. Both
constructions give total variable adjustment of the
travel of the actuator by limiting movement in the
upward direction. Refer to figures 4 and 5.
Others
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.
