Introduction

Scope of Manual

This instruction manual provides information on installation, maintenance, and parts ordering for the Fisher 585C
piston actuators. Refer to separate instruction manuals for information about other equipment and accessories used
with these actuators.

Information for the 585CLS long stroke actuator can be found in the Fisher 585CLS instruction manual
(D103793X012).

Do not install, operate, or maintain a 585C Series actuator without being fully trained and qualified in valve, actuator,
and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important

to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If
you have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.

Instruction Manual

D102087X012

Description

585C pneumatic piston actuators ( figure 1) provide accurate throttling or on-off control of sliding-stem valves. The
585C actuator uses a double-acting cylinder, which requires air pressure for operation.

Size 25 and 50 actuators are available as a springless construction or with a bias spring. Depending on configuration,
the bias spring will retract or extend the piston rod upon loss of cylinder air pressure. Size 60 through 130 actuators are
available as springless constructions only.

585C actuators are typically supplied with a DVC6200 digital valve controller, or a 3600 P/P or I/P analog positioner.
The 585C actuator is available with a top-mounted or side-mounted manual handwheel, depending on actuator size.

Specifications

Specifications for the 585C piston actuators are given in table 1. Some individual actuators come from the factory with
specifications stamped on a nameplate attached to the yoke.

Principle of Operation

The585Cpistonactuator(figures2and3)usesapistonthatmovesinsidetheactuatorcylinder.AnO-ring(seefigure

3) 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
onesideofthepiston,anddecreasingitontheother.Thismoves the piston up or down, and results in a repositioning
of the valve plug.

Actuator with Handwheel (figures 2 and 5)

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 5.

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.

Actuator with Spring Return (figure 3)

585C size 25 & 50 actuators are available with bias springs in two configurations. The 585C actuator, with the bias
spring under the piston, fully retracts the actuator stem upon loss of cylinder pressure. The 585C actuator, with the
bias spring on top of the piston, fully extends the actuator stem upon loss of cylinder pressure. No additional parts are
required to convert from one actuator type to the other.

For more detailed information on the 3610 positioner and DVC6200 digital valve controllers, refer to the Principle of
Operation section in the 3610 and DVC6200 Instruction Manuals.

Installation

WARNING

To avoid personal injury or property damage caused by cylinder fracture as a result of piston impact, install the stem
connector securely before supplying pressure to the positioner. Use only a regulator-controlled air supply to move the
actuator piston so that you can install the stem connector. Do not use the positioner to move the actuator piston before
installing the stem connector.

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.

To avoid personal injury or property damage caused by bursting of pressure-retaining parts, be certain the cylinder
pressure or other pressure ratings do not exceed the limits listed in table 1. Use pressure-limiting or pressure-relieving
devices to prevent cylinder pressure or other pressure ratings from exceeding these limits.

Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance sections in this
instruction manual.

When an actuator and valve are shipped together as a control valve assembly, the actuator is normally mounted on the
valve. Follow the valve instructions when installing the control valve in the pipeline. If the actuator is shipped
separately or if it is necessary to mount the actuator on the valve, perform the Actuator Mounting procedures in this
instruction manual corresponding to your actuator size. For information on mounting valve positioners, refer to the
3610 or DVC6200 instruction manuals for details.

If a 585C actuator is being installed without a positioner, the cylinder loading pressures should be supplied through a
4-way solenoid valve or a switching valve. The bottom side of the piston is pressured through the bottom side of the
mounting flange on the actuator yoke (key 6, figures 4 and 6) for sizes 25 and 50 or the connection at the lower side of
the cylinder (key 1, figure 9 to 12) for sizes 60 to 130. The top side of the piston is pressured through the connection in
the cylinder cover (key 1 for figures 4, 6; and 9 to 12).

The supply pressure medium should be clean, dry filtered air. If the supply source is capable of exceeding the
maximum actuator operating pressure or positioner supply pressure, appropriate steps must be taken during
installation to protect the positioner and all connected equipment against overpressure.

WARNING

Dropping the actuator and any attached accessories and/or valve may cause personal injury and/or equipment damage. For
all mounting procedures use an adequately sized chain, sling, hoist, or crane to handle the actuator and any attached

accessories and/or valve. Use caution during lifting and handling to prevent slippage, swinging, faulty equipment
connections, or sudden shock loads.

CAUTION

To avoid damage to actuator parts and difficult operation of actuator handwheels, open the bypass valve before using a
handwheel.

If manual operation is required, the actuator should be equipped with a manual handwheel. To manually move the
piston rod with the handwheel, first open the bypass needle valve(key66forsizes25and50,figure8;key92forsizes
60 to 130, figure 13), place the handwheel pointer in the neutral position, and insert the locking pin in the sleeve
assembly (for size 60-130). Then turn the handwheel in the selected direction as indicated on the wheel.

The control valve should be located where it will be accessible for servicing. Room should be left above and below the
control valve to permit removal of the actuator and valve plug.

Bypass Assembly

The bypass is furnished as shown in figures 5, 7, 8, and 13 only when a handwheel actuator is specified. The bypass
allows the pressure to equalize on either side of the piston, so that the manual actuator can be used to position the
valve.

Flow through the bypass tubing is controlled by an angle needle valve (key 66 for figures 5, 7, and 8; and key 92 for
figure 13), which is operated manually. This valve should be closed when air pressure is being used to operate the
valve.

Three-Way Valve Applications Note

WARNING

To avoid loss of control of process fluid and subsequent personal injury or property damage caused by bursting of
pressure-retaining parts, be sure the cylinder pressure does not exceed 80 psig in high cycle-rate, fast stroking speed,
three-way valve applications.

In three-way valve applications where the actuator fully strokes at a frequency of once per minute or faster, and the
stroking speed is rapid (less than 0.5 seconds per stroke), there is a possibility that the stem can fracture at the plug if
the actuator cylinder pressure is greater than 80 psig. This can cause loss of control of process fluid and further
damage to the actuator. Consideration should be given to the use of high-strength, fatigue-resistant stem materials in
these applications.
