Description

The Fisher 685 is a double acting piston actuator (figure 1) that provides accurate, high thrust output for short to long

travel applications. This actuator is designed for use with a variety of medium to large Fisher sliding-stem control

valves including the easye™ and FB.

The 685 family is available in several configurations to cover a wide range of application requirements. Typical travels

range from 8-7/8 through 23-7/8 inches in cylinder diameters from 12 through 18 inches and 2 through 23-7/8 inches

in cylinder diameters from 20 through 26 inches. Thrust capabilities extend to 79,000 lbf and above with special

constructions.

The 685 can be used with the FIELDVUE™ DVC6200 digital valve controller for throttling applications, or with

switching valves for onoff control. This actuator can also be fitted with volume boosters for fast stroking

requirements. Constructions are also available with side-mounted manual handwheels to extend or retract the piston

rod.

Principle of Operation

685 piston actuators utilize a pneumatically controlled piston that moves inside of a cylinder to generate thrust. A seal

contained on the circumference of the piston provides a seal between the piston and the cylinder, preventing supply

pressure leakage.

From an equilibrium state, the actuator operates by reacting 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 attached control valve. Travel can be adjusted using travel stops or cutoffs within a valve

positioner, which both limit the travel range of the actuator.

An optional handwheel manual override is capable of extending or retracting the actuator manually and can be

engaged at any position from full open to full close. This override utilizes a worm gear assembly that is attached to the

stem connector and not attached to the cylinder or piston rod. This enables the manual override to reposition the

control valve even if the actuator cylinder or piston is removed for maintenance.

Specifications

Specifications for 685 piston actuators are given in table 1. Refer to the nameplate affixed to the actuator yoke for

specifications specific to individual constructions.

Installation

WARNING

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 pressures 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 section in this

instruction manual.

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

Special care must be taken when installing an actuator in a horizontal service orientation. To avoid cantilever loads on the

valve stem and yoke, it is the customer’s responsibility to ensure proper support for a horizontal actuator.

When an actuator and control valve are shipped together as a control valve assembly, the actuator is normally

mounted on the valve. Follow the valve instructions when installing the 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. Refer to the individual product instruction manuals for the installation or mounting of a FIELDVUE

DVC6200 digital valve controller or 3610 positioner.

If the 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 top and bottom sides of the piston are pressurized through the upper

and lower heads (i.e. top and bottom of the cylinder).

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 over pressurization.

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.

ThreeWay Valve Applications Note

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.

Instruction Manual

Actuator Mounting

The following procedure describes how to mount a 685 actuator on a pushdowntoclose valve so that the piston rod

to valve plug stem connection allows full travel and proper shutoff. Key numbers referenced in the following steps are

showninfigures2and3.

If you purchase a 685 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. Also avoid damage to the valve plug

stem by careful use of tools during travel adjustment.

1. With the valve assembled and actuator mounted, make sure the valve plug is in the closed position. Then turn the

two stem locknuts (if present) all the way onto the stem thread.

2. Starting with the cylinder fully retracted, manually, or with air pressure, extend the piston rod extension to the

specified valve travel.

3. Attach the stem connector (key 18), clamping the piston rod (key 17) extension to the valve stem. Be sure you also

attachthefeedbackarmandtravelindicator.

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 18) securely, lock the stem locknuts (if present)

against the connector, and adjust the indicator scale (key 22) on the yoke (key 21) 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.

Handwheel Operation

If manual operation is required, the actuator should be equipped with a manual handwheel.

CAUTION

To avoid damage to actuator parts and difficult operation of actuator handwheels, open the bypass valve (key 66) before

using a handwheel.

The bypass assembly is furnished 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 control valve. Flow

through the bypass tubing is controlled by an angle needle valve, which is operated manually. This valve should be

closed when air pressure is being used to operate the actuator.

Key numbers referenced in the following steps are shown in figure 3. Refer to table 6 for turns-per-inch of travel

specifications.

Note

Depending on construction , the handwheel may have operation information stamped into the part. Always refer to steps 3 and 4

for operation information specific to push-down-to-close and push-down-to-open valves.

3. For a pushdowntoclose valve: Rotate the handwheel (key 45) clockwise to close the valve and counterclockwise

to open the valve.

4. For a pushdowntoopen valve: Rotate the handwheel (key 45) counterclockwise to close the valve and clockwise

to open the valve.

5. To disengage the manual handwheel, rotate the handwheel (key 45) to relieve any load placed on the override

engage pin (key 38), turn the engage pin control knob (key 33) counter-clockwise until it stops.

Maintenance

WARNING

Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:

DDo not remove the actuator from the valve while the valve is still pressurized.

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

DDisconnect 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.

DUse bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

on both sides of the valve. Drain the process media from both sides of the valve.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when

loosening the packing box pipe plug.

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

media.
