Fisherr585C Piston Actuators
The 585C linear piston actuator is a powerful,
double-acting actuator that provides accurate
throttling or on-off operation for sliding-stem control
valves.
The 585C piston actuator family is available in sizes 25
to130tocoverawiderangeofthrustandtravellength
requirements. It can be used with switching valves for
on-off control, or with the DVC6200 digital valve
controller or 3600 positioner for throttling
applications.
The 585C has a wide-range of supply pressure
capabilities, up to 150 psig. As the 585C is
double-acting, the positioner supplies air to both sides
of the piston, resulting in stiff, precise movement and
control.
Information for the 585CLS long stroke actuator can
be found in Fisher bulletin 61.2:585CLS
(D103792X012).
Features
High Thrust Capability-- With standard air supply,
the Size 130 Fisher 585C can produce up to 111,000
Newtons (25,000 lbs) of force.
Wide Range of Sizes-- The 585C family of actuators
offers a wide range of sizes, with piston areas of 168
sq cm (26 sq in) up to 1,429 sq cm (221.5 sq in).
Rugged Construction-- The 585C standard yoke
material is ductile iron, resulting in robust
construction and increased thrust capability.

Broad Travel Capability-- 585C piston actuators
provide standard travel lengths of up to 203 mm (8
inches).
High-Performance Instrumentation-- 585C
actuators are available with a variety of positioners
and accessories, including the FIELDVUE DVC6200
digital valve controller. The 377 trip valve and tank

Features and Advantages
Table 1. Features and Advantages
Features Advantages
High thrust capability With air supply capability of up to 150 psig, the 585C can produce up to 111,000 Newtons (25,000 pounds) thrust to
overcome high valve unbalance.
Stroke Length Capability Depending on size, strokes of up to 203 mm (8 inches) are available.
Wide range of sizes The 585C is available in standard sizes 25, 50, 60, 68, 80, 100, and 130.
Valve mounting capability Depending on size, the 585C can be mounted to yoke boss diameters of 2-1/8 inches through 5-inches, and valve
stem diameters of up to 1-1/4 inch.
Positioner mounting capability Universal NAMUR mounting provides a consistent mounting method for all sizes. This mounting capability provides
vibration resistance per ISA-S75.13.
High frequency response The double acting construction allows quick response to instrument signals.
Stiff construction Pressure on both sides of the piston, plus the relatively small volume of air within the cylinder, results in stiff, precise
positioning.
Handwheels 585C size 25 and 50 actuators are available with a top-mounted handwheel. All other 585C actuator sizes can
accommodate a side-mounted handwheel.
Bias springs
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.

Principle of Operation
The585Cpistonactuator(figures1and2)usesa
piston that moves inside the actuator cylinder. An
O-ring (see figure 1) 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
Actuator with Handwheel (figures 3
and 6)
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 6.
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.

(figure 4)
585C size 25 & 50 actuators are available with bias
springs. The 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 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.

Instrument and Accessory
Selection
An excellent selection of sensitive and accurate
instrumentsandaccessoriesisavailablefor585C
piston actuators. These include FIELDVUE DVC6200
digital valve controllers, 3600 pneumatic (P/P) and
electro-pneumatic (I/P) positioners, TopWorx™ DXP
M21GNEB electrical valve stem position switch, 377
trip valve, 4200 electronic position transmitter, and
limit switches. They are described in separate
publications. Contact your Emerson Process
Management sales office for details.
Installation
The actuator may be installed in any orientation but
normal installation is with the actuator vertical above
the valve. Actuator and positioner dimensions are
showninfigures6,7,and8.
If the supply source is capable of exceeding the
maximum actuator operating pressure or instrument
supply pressure, appropriate steps must be taken
during installation to protect the instrument and all
connected equipment against overpressure.
Actuator Data
See table 2 for piston cylinder clearance volumes, table
3 for yoke boss and valve stem diameters, and tables 4,
5, 6, 7, and 8 for actuator thrust capabilities.

X indicates where the listed supply pressure will exceed the maximum thrust allowable.
1. The maximum design pressure for size 25 through 100 actuators is 10.3 bar (150 psig). Size 68 and 130 actuators are limited to 9.7 and 7.8 bar (140 and 113psig)respectively.
2. The size 25 and 50 data is for the construction without a bias spring.
3. Minimum operating pressure for sizes 60-130 actuators is 2.4 bar (35 psig).
4. The size 68 actuator with a handwheel is limited to 40000 Newtons (9000 lb) thrust.
