Instruction Manual
D103793X012
Specifications
This product was intended for a specific range of service conditions‐‐pressure, pressure drop, process and ambient
temperature, temperature variations, process fluid, and possibly other specifications. Do not expose the product to
service conditions or variables other than those for which the product was intended. If you are not sure what these
conditions or variables are, contact your Emerson sales office
product serial number and all other pertinent information that you have available.
or Local Business Partner for assistance. Provide the
Inspection and Maintenance Schedules
All products must be inspected periodically and maintained as needed. The schedule for inspection can only be
determined based on the severity of your service conditions. Your installation might also be subject to inspection
schedules set by applicable governmental codes and regulations, industry standards, company standards, or plant
standards.
In order to avoid increasing dust explosion risk, periodically clean dust deposits from all equipment.
When equipment is installed in a hazardous area location (potentially explosive atmosphere), prevent sparks by proper
tool selection and avoiding other types of impact energy. Control Valve surface temperature is dependent upon
process operating conditions.
WARNING
Control valve surface temperature is dependent upon process operating conditions. Personal injury or property damage,
caused by fire or explosion, can result if the valve body surface temperature exceeds the acceptable temperature for the
hazardous area classification. To avoid an increase of instrumentation and/or accessory surface temperature due to process
operating conditions, ensure adequate ventilation, shielding, or insulation of control valve components installed in a
potentially hazardous or explosive atmosphere.
Parts Ordering
Whenever ordering parts for older products, always specify the serial number of the product and provide all other
pertinent information that you can, such as product size, part material, age of the product, and general service
conditions. If you have modified the product since it was originally purchased, include that information with your
request.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher product, because they may void your warranty, might adversely affect
the performance of the product, and could cause personal injury and property damage.

Installation
These safety instructions are limited to pneumatic actuators which are operating using air or nitrogen (inert gas). If the
application requires use of a flammable or hazardous gas, you must contact your Emerson sales office
Business Partner for assistance.
WARNING
To avoid personal injury and property damage caused by bursting of parts and to avoid parts damage, malfunction of
control valve, or loss of control of the process caused by excessive pressure, do not exceed the maximum pressures or
temperatures for this actuator, as given in the applicable product literature or on the nameplate. Use pressure‐limiting or
pressure‐relieving devices to prevent the actuator pressure from exceeding specified limits. If you cannot determine the
limits for this product, contact your Emerson Automation Solutions sales office before proceeding.
D To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
operations.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D If hoisting the actuator, use a nylon sling to protect the surfaces. Carefully position the sling to prevent damage to the
actuator tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging
might slip. Be sure to use adequately sized hoists and chains or slings to handle the assembly.
D If installing into an existing application, also refer to the WARNING in the Maintenance section.
or Local
Operation
WARNING
When moving the actuator stem or shaft with loading pressure applied, use caution to keep hands and tools out of the
actuator travel path. Personal injury and property damage is possible if something is caught between the actuator stem
and other control valve assembly parts.
Maintenance
WARNING
Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:
D Do not remove the actuator while the valve is pressurized.
D Always wear protective gloves, clothing, and eyewear.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.

D Vent any pneumatic pressure from the actuator and relieve any actuator spring pre‐compression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D To avoid personal injury due to the sudden uncontrolled movement of parts, do not loosen the stem connector cap
screws when the stem connector has spring force applied to it.
D Never apply pressure to a partially assembled actuator unless all pressure‐retaining parts have been installed properly.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

Scope of Manual
This instruction manual provides information on installation, maintenance, and parts ordering for the Fisher 585CLS
Long Stroke piston actuator. Refer to separate instruction manuals for information about other equipment and
accessories used with these actuators.
Do not install, operate, or maintain a 585CLS 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.
Description
585CLS piston actuators are available with travel capabilities exceeding 203 mm (8 inches) up through 610 mm (24
inches). This actuator is available with a manual handwheel, which can be used to open, close, or position the valve.
The manual handwheel may also be used as a stop to limit the upward travel of the valve plug.
The 585CLS actuator typically is equipped with either a FIELDVUE™ DVC6200 digital valve controller or 3600
positioner for throttling service. For on-off service, the actuator cylinder is loaded and unloaded through the operation
of a solenoid valve, pneumatic switch, or similar equipment.
