585C Actuator
The Type 585C Linear Piston Actuator
The Type 585C linear piston actuator is a powerful,
double-acting actuator that provides accurate
throttling or on-off operation for sliding-stem control
valves.
The Type 585C piston actuator family is available in
sizes 25 to 130 to cover a wide range of thrust and
travel length requirements. It can be used with
switching valves for on-off control, or with the Fisher
DVC6000 Series digital valve controller or 3600
Series positioner for throttling applications.
The Type 585C has a wide-range of supply pressure
capabilities, up to 150 psig. As the Type 585C is
double-acting, the positioner supplies air to both
sides of the piston, resulting in stiff, precise
movement and control.
The 585C piston actuator is also available in a long
stroke version with travel capabilities up through 610
mm (24 inches).

Advantages
With air supply capability of up to 150 psig, the Type 585C can produce up to
111,000 Newtons (25,000 pounds) thrust to overcome high valve unbalance. Special
constructions can produce thrusts of up to 137,000 Newtons (30,800 pounds).
Depending on size, strokes of up to 203 mm (8 inches) (standard) are available.
Longer travels of up to 610 mm (24 inches) are available upon request.
The Type 585C is available in standard sizes 25, 50, 60, 68, 80, 100, and 130.
Larger cylinder sizes are available for special applications.
Depending on size, the Type 585C can be mounted to yoke boss diameters of 2-1/8
inches through 5-inches, and valve stems of up to 1-1/4 inch diameter. Special
constructions will accommodate a 7-inch yoke boss and a 2-inch valve stem.
Universal NAMUR mounting provides a consistent mounting method for size 25
through 130 actuators. This mounting capability provides vibration resistance per
ISA-S75.13.
The double-acting construction of the Type 585C allows quick response to
instrument signals.
Pressure on both sides of the piston, plus the relatively small volume of air within the
cylinder, results in stiff, precise positioning.
Type 585C size 25 and 50 actuators are available with a top-mounted handwheel. All
other 585C actuator sizes can accommodate a side-mounted handwheel.
The sizes 25 and 50 are available with bias springs. A bias spring under the piston
fully retracts the actuator stem upon loss of supply air, while a bias spring on top of
the piston fully extends the actuator stem. The spring bias mode is easily reversed
without the need for additional parts.

585C Actuator
E0409 / IL
Figure 3. Type 585C Piston Actuator Without Springs
Principle of Operation – 585C
The Type 585C piston actuator (figures 2 and 3)
uses a piston that moves inside the actuator
cylinder. An O-ring (see figure 2) provides a seal
between the piston and the cylinder.
From an equilibrium state, the actuator reacts to a
force unbalance that is created by increasing supply
pressure on one side of the piston,and decreasing it
on the other. This moves the piston up or down, and
results in a repositioning of the valve control
element.
E0410 / IL
Figure 4. Type 585C Piston Actuator with Handwheel
Actuator with Handwheel (figures 4 and 13)
The handwheel version can be used to open or
close the valve manually (either during normal
operation or in an emergency), to position the valve
at any point in the stroke, or to act as a travel stop.
Size 25 and 50 actuators use an integral
top-mounted handwheel. See figure 13.
Size 60 to 130 actuators use a side-mounted
handwheel, and come with a spring-loaded ball
detent which prevents vibration from changing the
handwheel setting. Handwheels for most types are
either 203 mm (8 inches) in diameter with beveled
gears or 432 mm (17 inches) in diameter with worm
gears.

Type 585C size 25 & 50 actuators are available with
bias springs. The Type 585C actuator with bias
spring has the spring under the piston and fully
retracts the actuator stem upon loss of cylinder
pressure. The bias spring in the Type 585CR
actuator is on top of the piston and fully extends the
actuator stem upon loss of cylinder pressure. No
additional parts are required to convert from one
actuator type to the other.
Type 585C Long-Stroke Construction
When especially high thrust or long stroke is
required, the Type 585C Long-Stroke piston actuator
is the answer (see figure 6). The versatility of the
Long-Stroke version allows accommodation of 16
different valve travels, up through 610 mm (24
inches). Available thrusts are impressive too, with
thrust capability of up to 137,800 newtons (30,800
lbs).

Instrument Selection
An excellent selection of sensitive and accurate
instruments is available for Type 585C piston
actuators. These include the DVC6000 Series digital
valve controller, as well as the 3600 Series
pneumatic (P/P) and electro-pneumatic (I/P)
positioners.
DVC6010/6020 Digital Valve Controller
FIELDVUEr DVC6000 Series digital valve
controllers, figure 7, are communicating,
microprocessor-based current-to-pneumatic
instruments. In addition to the traditional function of
converting a current signal to a pressure signal,
DVC6000 Series digital valve controllers, using
HARTr communications protocol, give easy access
to information critical to process operation. This can
be done using a Model 275 HART Communicator at
the valve or at a field junction box, or by using a
personal computer or a system console within the
control room. Using HART communication protocol,
information can be integrated into a control system
or received on a single loop basis.
DVC6000 Series digital valve controllers can be
used on single- or double-acting actuators. The
digital valve controller receives feedback of the valve
travel position plus supply and actuator pneumatic
pressure. This allows the instrument to diagnose not
only itself, but also the valve and actuator to which it
is mounted. This provides you with very cost
effective maintenance information, so that required
maintenance can be performed on the instrument
and valve when there really is a need.
Wiring is economical because DVC6000 Series
digital valve controllers use two-wire 4 to 20 mA loop
power. This provides for low cost replacement of
existing analog instrumentation. The DVC6000
Series digital valve controller’s two-wire design
avoids the high cost of running separate power and
signal wiring.
Principle of Operation—DVC6010/6020
DVC6000 Series instruments receive a set point and
position the valve where it needs to be. See figure 8.
D The input signal provides electrical power and
the set point simultaneously. It is routed into the
terminal box through a twisted pair of wires.

W7960 / IL
Figure 7. Type DVC6010 Digital Valve Controller Mounted on
Type 585C Piston Actuator
D The input signal is then directed to the printed
wiring board assembly where the microprocessor
runs a digital control algorithm resulting in a drive
signal to the I/P converter.
D The I/P converter assembly is connected to
supply pressure and converts the drive signal into a
pressure output signal.
D The I/P output is sent to the pneumatic relay
assembly. The relay is also connected to supply
pressure and amplifies the small pneumatic signal
from the I/P converter into a single larger pneumatic
output signal used by a single-acting actuator. For
double-acting actuators, the relay accepts the
pneumatic signal from the I/P converter and provides
two pneumatic output signals.
D The change in relay output pressure to the
actuator causes the valve to move.
D Valve position is sensed through the feedback
linkage by the instrument’s travel sensor. The travel
sensor (or potentiometer) is electrically connected to
the printed wiring board to provide a travel feedback
signal used in the control algorithm.
The valve continues to move until the correct
position is attained.

3600 Series Positioner
3600 Series pneumatic (P/P) and electro-pneumatic
(I/P) positioners are used in combination with either
single or double acting actuators to accurately
position control valves used in throttling applications.
These accurate and vibration-resistant positioners
provide a valve position proportional to a pneumatic
or a dc current input signal. Low steady-state air
consumption contributes to efficient operation.
The Type 585C piston actuator can be controlled
with the Type 3610JP or 3611JP pneumatic (P/P)
positioner, and the 3620JP or 3621JP
electro-pneumatic (I/P) positioner.
Principle of Operation—3600 Series
A switching device is required to control the loading
and unloading of supply pressure. A 4-way solenoid
or a 3600 Series positioner can be used for throttling
service. The P/P positioner accepts a pneumatic
input signal, whereas the I/P positioner accepts a dc
current signal from a control device.

summing beam, pivoting the summing beam
clockwise and causing relay B to exhaust upper
actuator cylinder pressure to atmosphere and relay
A to increase lower actuator cylinder pressure. As a
result, the actuator stem retracts and the feedback
arm pivots counterclockwise reducing the force
applied to the summing beam by the range spring.
As the actuator stem retracts, the range spring force
to the summing beam continues to reduce until the
summing beam torques are in equilibrium. At this
point, the actuator stem is in the correct position for
the specific input signal applied.
The I/P positioner is a combination of a P/P
positioner with a current-to-pressure converter. The
converter provides a 0.2 to 1.0 bar (3 to 15 psig)
output pressure proportional to the 4 to 20
milliampere input signal. The 0.2 to 1.0 bar (3 to 15
psig) output pressure becomes the input signal
pressure to the P/P pneumatic positioner.
W4901–1*/IL
Figure 10. Adjustment for 3600 Series Positioners
The P/P positioner is a force-balanced instrument
that provides an actuator stem position proportional
to the pneumatic input signal, as shown in figure 11.
For direct action, input signal pressure from a
pneumatic instrument is channeled to cavity A in the
input module. An increase in input signal pressure
results in a downward force on the summing beam,
pivoting the summing beam counterclockwise. This
moves the flapper slightly toward the nozzle,
increasing the nozzle pressure. As nozzle pressure
increases, the relay beam pivots clockwise, causing
relay B to increase upper cylinder pressure and
Relay A to exhaust lower cylinder pressure of the
actuator.
As a result, the actuator stem extends and the force
applied to the summing beam by the range spring
increases as the feedback lever rotates clockwise.
This force, which opposes the downward force on
the summing beam caused by the increasing input
signal pressure, continues to increase until the
summing beam torques are in equilibrium. At this
point, the actuator stem is in the correct position for
the specific input signal applied.
For reverse action, input signal pressure is
channeled to both cavities A and B. An increase in
signal pressure results in an upward force on the

Accessories
Type 304 Electrical Valve Stem Position Switch—
A cam operated limit switch assembly that can
house from one to six snap-acting switches. The
position switch shaft is rotated by linear motion of
the valve stem and each cam can be adjusted to
activate its switch at the proper travel.
377 Series Trip Valve—Used when a specific valve
fail action is required when supply pressure falls
below a specified pressure. Should supply pressure
fall below the trip point, the trip valve can be set to
cause the actuator piston to fail up, fail down or
lock-in-last position.
4200 Series Electronic Position Transmitter—The
position transmitter provides an electrical signal that
is proportional to the valve stem position. Depending
on the type of transmitter ordered, it provides a
transmitter signal only, position switches only, or a
transmitter signal with position switches for accurate
valve position indication.
GO Series Limit Switches (Size 60 to 130
only)—Can be mounted on the yoke cover plate to
electrically indicate open or closed positions of the
valve.
