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 or Local
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.
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.

Principle of Operation
The 585CLS piston actuator uses a piston that moves inside the actuator 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 control element.
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 585CLS 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 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 (key 54, figure 2), place the handwheel indicator in
the neutral position, and insert the locking pin in the sleeve assembly. 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 figure 2 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 54, figure 2), 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.
Actuator Mounting
The following procedure describes how to mount a 585CLS actuator on a push-down-to-close valve so that the piston
stem to valve plug stem connection allows full travel and proper shutoff. Key numbers referenced in the following
steps are shown in figures 2 and 3.
If you purchase a 585CLS actuator for field installation on a control valve, mount the actuator on the valve and secure it
to the bonnet with the eight bonnet-to-actuator bolts. The stem connection should then be made up to clamp the
actuator stem and valve plug stem together to provide proper valve travel.
CAUTION
To avoid damaging the seating surfaces, do not rotate the valve plug while it is seated. Avoid damage to the valve plug
stem by careful use of tools during travel adjustments.
1. With the valve assembled and actuator mounted, make sure the valve plug is in the closed position. Then turn the
two stem locknuts (key 23) all the way onto the stem thread.
2. Starting with the cylinder fully retracted, manually or with air pressure extend the piston rod extension the specified
valve travel.
3. Attach the stem connector (key 22), clamping the pistonrodextensiontothevalvestem.Besureyoualsoattach
the feedback arm (key 4) and travel indicator (key 3).
4. Cycle the actuator to check availability of desired total travel and that the valve plug seats before the cylinder
reaches the end of its stroke. You can make minor travel adjustments, if necessary, by loosening the stem
connector slightly, tightening the locknuts together, and (with the valve plug off the seat) screwing the stem either
into or out of the stem connector by means of a wrench on the locknuts.
5. If the total travel is adequate, tighten the stem connector (key 22) securely, lock the stem locknuts (key 23) against
the connector, and adjust the indicator scale (key 7) on the yoke (key 1) to show valve plug position.
6. Provide a gauge, if necessary, to measure the pressure to the actuator. Make a final adjustment on the positioner to
set the starting point of valve travel and to obtain full travel for the given instrument range.
Handwheels
Key numbers referenced in the following steps are shown in figures 2 and 3.
