WARNING

To avoid loss of control of processfluid and subsequent personal injury orproperty damage caused by bursting ofpressure-retaining parts, be sure thecylinder pressure does not exceed 80psig in high cycle-rate, fast stroking

speed, three-way valve applications.

In three-way valve applications where the actuatorfully strokes at a frequency of once per minute or fast-

er, and the stroking speed is rapid (less than 0.5 sec-onds per stroke), there is a possibility that the stemcan fracture at the plug if the actuator cylinder pres-sure is greater than 80 psig. This can cause loss ofcontrol of process fluid and further damage to the ac-tuator. Consideration should be given to the use ofhigh-strength, fatigue-resistant stem materials inthese applications.

This problem appears to be application sensitive, in

particular, water quench applications in steel millswhere stroking speed and cylinder pressure are high.There have been no reported occurrences of this typeof failure in other applications.

W6907/IL

Description

The compact Type 585C and 585CR pneumaticspring-and-piston actuators (figure 1) provide accuratethrottling or on-off control of sliding-stem valves. Bothtypes have a double-acting cylinder requiring air pres-sure for operation. The Type 585C actuator with biasspring action fully retracts the piston stem upon loss ofcylinder pressure, while the Type 585CR actuator withbias spring action fully extends the piston stem uponloss of cylinder pressure. No additional parts are re-quired to convert from one actuator type to the other.Both actuators are available with or without a top-mounted handwheel.

Installation

WARNING

To avoid personal injury or propertydamage caused by bursting of pressure-retaining parts, be certain the cylinderpressure does not exceed the limitslisted in table 1. Use pressure-limiting orpressure-relieving devices to preventcylinder pressure from exceeding theselimits.

A Type 585C or 585CR actuator is normally shippedmounted on a valve. Refer to the appropriate valveinstruction manual when installing the valve in thepipeline. If necessary to mount a separately shippedactuator on a valve, perform the procedures describedin the Actuator Mountingportion of this section.

WARNING

Dropping the actuator and any attachedaccessories and/or valve may cause per-sonal injury and/or equipment damage.For all mounting procedures use an ad-equately sized chain, sling, hoist, orcrane to handle the actuator and any at-tached accessories and/or valve. Usecaution during lifting and handling toprevent slippage, swinging, faultyequipment connections, or suddenshock loads.

Actuator Mounting

The following procedure describes how to mount aType 585C or 585CR actuator on a push-down-to-close valve so that the piston stem to valve plug stemconnection allows full travel and proper shutoff. Keynumbers referenced in the following steps are shown

in figures 2 through 6.

1. If not already removed, remove the stem connector(key 12) by loosening the cap screws (key 14).

2. Thread the stem connector nuts (keys 13 and 15)onto the valve stem, and run the nuts to the bottom ofthe valve stem threads.

3. Push the valve plug stem until the valve plug isclosed for push-down-to-close valve plug action.

4. Place the actuator on the bonnet of the valve andsecure the actuator tightly to the bonnet with the yokelocknut.

CAUTION

In the following procedure, do not rotatethe valve plug while it is seated sincethis may cause damage to the seatingsurface and thereby allow excessiveleakage. Also, during adjustment, usetools carefully to avoid damaging thevalve plug stem. A damaged valve plugstem could cut the packing and allowleakage.

Note

When using an actuator with handwheelin the following step to stroke the valveplug, be sure the bypass valve (key 66,figure 3 or 5) is open. Rotating the hand-wheel (key 47, figure 3 or 5) clockwiseextends the actuator stem (key 10); ro-tating the handwheel counterclockwiseretracts the actuator stem.

5. Perform one of the following procedures (a or b asappropriate):

a. For a Type 585C actuator (figure 2) withpush-down-to-close valve, manually move thevalve plug to the seated position. Rotate the hand-wheel or apply pressure to the pressure connectionin the cylinder (key 1) until the piston (key 3) andactuator stem (key 10) move down the specifiedtravel. Run the stem connector nut (key 13) up onthe valve stem until it contacts the actuator stem.Back off the handwheel or reduce cylinder pressure

enough to move the actuator stem away from thestem connector nut approximately 1/4-inch. Rotatethe stem connector nut, so it moves up the valvestem, an additional two turns. Rotate the hand-wheel or apply pressure to the pressure connectionin the cylinder (key 1) until the actuator stem (key10) again contacts the stem connector nut. Be sure

the flats on the actuator stem are perpendicular tothe scale indicator web on the yoke (key 6). Adjustthe stem connector nut as necessary, so that theflats on the nut and the actuator stem are parallel.Clamp the actuator stem and stem connector nuttogether with the stem connector (key 12) and thetwo cap screws and hex nuts (keys 14 and 23).Run the hex nut (key 15) up the valve stem andtighten against the stem connector nut (key 13).

b. For a Type 585CR actuator (figure 4) withpush-down-to-close valve, manually move thevalve plug to the seated position. Run the stemconnector nut (key 13) up the valve stem until itcontacts the actuator stem (key 10). Rotate thehandwheel or apply pressure to the pressure con-nection in the yoke (key 6) to move the actuatorstem (key 10) approximately 1/4-inch away fromthe stem connector nut. Rotate the stem connectornut so that it moves up the valve stem two fullturns. Manually move the valve plug so that thestem connector nut again contacts the actuatorstem. Be sure the flats on the actuator stem areperpendicular to the scale indicator web on theyoke (key 6). Adjust the stem connector nut, asnecessary, so that the flats on the nut and the ac-tuator stem are parallel. Clamp the actuator stem

and stem connector nut together with the stem con-nector (key 12) and the two cap screws and hexnuts (keys 14 and 23). Run the hex nut (key 15) upthe valve stem and tighten it against the stem con-nector nut (key 13).

6. Cycle the actuator several times to check forproper operation.

Note

In the following step, make sure the cor-rect travel indicator scale (key 19) is

used per the Parts Listfor the desiredtravel.

7. If necessary, remove the travel indicator scalescrews (key 18) and reposition the travel indicatorscale (key 19) so that the scale arrow points in thesame direction as the valve plug moves when open-ing. Close the valve. Adjust the scale up or down sothat the stem connector (key 12) indicator lines up withthe closed mark on the scale. Secure the scale withthe scale screws.

Handwheel Adjustment

Key numbers referenced in the following steps areshown in figure 3 for the Type 585C actuator and infigure 5 for the Type 585CR actuator.

The handwheel assembly on a Type 585C or 585CR

actuator may be used as an adjustable travel stop tolimit full upward or downward travel of the actuatorstem (key 10), or as a manual actuator to fully strokethe valve. When the neutral indicator (key 42) is in theneutral position, travel is not restricted. With clockwisehandwheel (key 47) rotation, the operating nut (key46) is screwed downward, forcing the actuator stem(key 10) down. With counterclockwise rotation, theoperating nut is screwed upward against the hand-wheel stem washer (key 45), pulling the actuator stemup.

Note

When using an actuator with handwheelto stroke the valve plug or position thetravel stop, be sure the bypass valve(key 66) is open.

Maintenance

Actuator parts are subject to normal wear and must beinspected and replaced as necessary. The frequencyof inspection and replacement depends on the severityof service conditions. This section provides two sepa-rate procedures, one on Replacing Handwheel Hous-ing O-Ring or Thrust Bearings, and the other on Re-placing Seals, Changing Action, or Changing BiasSpring(s).

For an actuator with handwheel, a grease fitting (key50, figure 3 or 5) is provided on the bearing cover (key38, figure 3 or 5) for periodic bearing lubrication withLubriplate MAG-1 lubricant (key 24, figure 3 or 5) orequivalent.

WARNING

Avoid personal injury from sudden re-lease of process pressure. Before per-forming any maintenance operations:

Disconnect any operating lines pro-viding air pressure, electric power, or acontrol signal to the actuator. Be surethe actuator cannot suddenly open orclose the valve.

Use bypass valves or completelyshut off the process to isolate the valvefrom process pressure. Relieve processpressure on both sides of the valve.Drain the process media from bothsides of the valve.

Vent the power actuator loadingpressure and release all bias springcompression force by slowly unscrew-ing the cylinder cover bolting in a criss-cross pattern.

Use lock-out procedures to be surethat the above measures stay in effectwhile you work on the equipment.

Replacing Handwheel Housing O-Ringor Thrust Bearings

Perform this procedure if inspecting or replacing thehandwheel housing O-ring, handwheel thrust bearings,or any other handwheel parts located above the cylin-der (key 1, figure 3 or 5). Inspection or replacement ofthe cylinder O-ring, handwheel stem, or handwheelstem jam nut (key 57, 56, or 52, figure 3 or 5) are cov-ered in the Replacing Seals, Changing Action, orChanging Bias Spring(s)procedure. Key numbers arereferenced in figure 3 for a Type 585C actuator and infigure 5 for a Type 585CR actuator.

Note

This procedure may be performed with-out removing the cylinder, or yoke (key

1 or 6) from the bonnet of the valve.Isolate the control valve from the line pressure, re-lease pressure from both sides of the valve body, anddrain the process media from both sides of the valve.Shut-off all pressure lines to the power actuator, andrelease all pressure from the actuator. Use lock-outprocedures to be sure that the above measures stay ineffect while you work on the equipment.

1. Shut off the bypass valve (key 66). Remove thecylinder pressure piping and bypass tubing from thebypass tees (key 68) on the cylinder (key 1).

2. Turn the handwheel (key 47) in the appropriatedirection so the neutral indicator (key 42) is behind the

NEUTRAL position of the neutral indicator plate(key 37).

3. Unscrew and remove the neutral indicator cover(key 35).

4. Remove the handwheel retaining ring, handwheel,and locking key (keys 48, 47, and 65).

5. Loosen the bearing cover set screws (key 51), andunscrew and carefully remove the bearing cover(key 38).

6. Remove the handwheel housing O-ring (key 58)and the top set of thrust bearings (key 39).

7. Since both the handwheel housing (key 36) and theoperating nut (key 46) have left-hand threads, unscrewthe handwheel housing by turning it clockwise off theoperating nut. Carefully remove the detent ball and

detent spring (keys 64 and 63), and remove the bot-tom set of thrust bearings (key 39).

8. Unscrew the handwheel stem cap screw (key 60)while using a 7/8-inch wrench to hold the handwheelstem (key 56). Remove the handwheel stem washer(key 45), and the operating nut (key 46) with attachedneutral indicator (key 42).

9. Unscrew the neutral indicator (key 42) counter-clockwise if necessary to separate it from the operat-ing nut (key 46).

10. If the neutral indicator (key 42) was removed, coatits threads with Loctite No. 242 sealant (key 70) or

equivalent and screw it into the operating nut (key 46).Position the 90-degree elbow of the neutral indicatorso that it will not interfere with the neutral indicatorcover (key 35) when assembled.

11. If necessary, replace the anti-rotation key (key40), by pushing the key outward from the cylinder (key1) then install the replacement key (key 40) into theanti-rotation hole of the cylinder.

12. Lubricate the inside surface of the operating nut(key 46) with Lubriplate MAG-1 lubricant (key 24) orequivalent. Install the operating nut with the attachedneutral indicator, and the handwheel stem washer (key45), onto the handwheel stem (key 56) and secure

with the handwheel stem cap screw (key 60). Tightenthe cap screw to 125 lbfft (169 Nm).

13. Place the bottom set of thrust bearings (key 39)on top of the cylinder (key 1). Insert the detent springand ball (keys 63 and 64) into the cylinder.

14. Install the handwheel housing O-ring (key 58) onthe handwheel housing (key 36). Since both the hand-wheel housing and the operating nut (key 46) haveleft-hand threads, thread the handwheel housing ontothe operating nut by turning it counterclockwise overthe operating nut until the handwheel housing is snugagainst the bottom set of thrust bearings (key 39).

15. Install the top set of thrust bearings (key 39) overthe handwheel housing (key 36).

16. Carefully slide the bearing cover (key 38) over thehandwheel housing (key 36) and thread the bearingcover hand tight onto the cylinder (key 1). Secure bytightening the set screws (key 51) to 13 lbfft (18Nm).

17. Install the locking key, handwheel, and handwheelretaining ring (keys 65, 47, and 48).

18. Screw the neutral indicator cover (key 35) handtight only onto the handwheel housing (key 36).

19. Install the bypass tubing with attached bypassvalve (key 66) into the bypass tees (key 68) in the cyl-inder (key 1).

Replacing Seals, Changing Action, orChanging Bias Spring(s)

Key numbers are referenced in figures 2 and 3 for aType 585C actuator and in figures 4 and 5 for a Type585CR actuator.

Isolate the control valve from the line pressure, re-lease pressure from both sides of the valve body, anddrain the process media from both sides of the valve.Shut-off all pressure lines to the power actuator, re-lease all pressure from the actuator, and release all

bias spring compression force by slowly unscrewingthe cylinder cover bolting in a crisscross pattern. Uselock-out procedures to be sure that the above mea-sures stay in effect while you work on the equipment.

For Type 585C actuators with push-only handwheel,be sure the handjack stem is backed out of the cylin-der as far as it will go to relieve any extra spring com-pression.

1. Remove the cylinder pressure piping. With a hand-wheel construction, perform steps 2. through 10. ofthe Replacing Handwheel Housing O-Ring or ThrustBearingsprocedure.

Note

In the following step, loosen each cylin-der-to-yoke cap screw a slight amountin turn in a crisscross pattern to keepthe cylinder square with the yoke whilerelieving spring precompression.

2. While carefully allowing bias spring precompressionto be slowly released, remove the cylinder-to-yoke capscrews and cylinder cover (keys 2 and 1).

3. Remove the cylinder (key 1). Set the cylinder on aprotective surface to prevent damage to the cylindersurfaces. With a handwheel construction, inspect thecylinder O-ring (key 57) and replace it if necessary,applying Lubriplate MAG-1 lubricant (key 24) or equiv-alent to the replacement O-ring.

4. Inspect the piston O-ring (key 8) and replace, ifnecessary. If the only further maintenance to be per-formed is replacement of the piston O-ring, skip tostep 11. of this procedure.

Note

Type 585C actuators may be used withor without the bias springs. In the fol-lowing procedures, references are madeto the bias springs. If the bias springsare not used, disregard references to

them when performing the maintenanceprocedures.

5. Perform one of the following disassembly proce-dures (a, b, c, or d as appropriate):

a. For Type 585C actuators without handwheel(figure 2), remove the piston cap screw (key 4),piston (key 3), bias spring(s) (key 16 and/or key17), and travel stop spacer (key 5).

b. For Type 585C actuators with handwheel(figure 3), remove the handwheel stem (key 56)with attached piston stud (key 69), piston (key 3),bias spring(s) (key 16 and/or key 17), and travel

stop spacer (key 5).

c. For Type 585CR actuators without hand-wheel (figure 4), remove the bias spring(s) (key 16and/or key 17), piston cap screw (key 4), travelstop spacer (key 5) and piston (key 3).

d. For Type 585CR actuators with handwheel(figure 5), remove the bias spring(s) (key 16 and/orkey 17), the handwheel stem (key 56) with at-tached piston stud (key 69), travel stop spacer (key5), and piston (key 3).

e. For Type 585C actuators with push-only

handwheel (figure 6), remove the cotter pin andslotted nut (keys 73 and 72) and lift off the hand-wheel. Remove the jam nut (key 52). Remove thecap screws (key 60) and lift off the handwheelhousing (key 36). Back the handwheel stem (key56) out of the housing. Inspect the O-rings (keys 57and 58). Replace these parts as necessary.

6. If inspection or replacement of the actuator stemO-ring or bearing (key 9 or 11) is necessary, performsteps 7. through 9. . Otherwise skip to step 10. ,being sure to comply with the note preceding step10. .

7. Loosen the two cap screws in the stem connector

(key 14) and remove it. If the actuator is mounted on avalve, separate the actuator stem (key 10) from thevalve plug stem. Remove the actuator from the valve.

8. To inspect the actuator stem bearing (key 11), ac-tuator stem O-ring (key 9), or backup ring (key 25 size50 only) remove the actuator stem (key 10) from theyoke (key 6). Replace these parts if necessary. ApplyLubriplate MAG-1 lubricant (key 24) or equivalent tothe replacement O-ring or bearing and install it into theyoke.

9. Install the actuator stem through the yoke.

Note

Make certain the travel indicator scale(key 19) correctly matches the travel perthe Parts List.

10. To achieve the desired construction (either a di-rect-acting Type 585C actuator or a reverse-actingType 585CR actuator), perform one of the followingassembly procedures (a or b as appropriate):

a. For Type 585C actuators (figures 2 and 3),

center the inner bias spring, if used, (key 17 pertable 2 or 3) around the center boss in the yoke(key 6). If used per table 2 or 3, center the outerbias spring (key 16) around the inner bias spring.The outer bias spring should be within the outerboss in the yoke. Put the travel stop spacer and thepiston (keys 5 and 3) on the actuator stem. ApplyLubriplate MAG-1 lubricant (key 24) or equivalentto the threads of the piston cap screw or pistonstud (key 4 or 69). Insert the piston cap screw, orstud plus attached handwheel stem (key 56),through both the piston and travel stop spacer andinto the actuator stem. Use a wrench on the flats ofthe actuator stem to prevent it from turning. Tighten

the piston cap screw, or stud plus attached hand-wheel stem, to 75 lbfft (102 Nm) for size 25 ac-tuators or 100 lbfft (136 Nm) for size 50 actua-tors.

b. For Type 585C actuators with push-onlyhandwheel (figure 6), lubricate the O-rings andhandjack stem threads with Lubriplate MAG-1 orequivalent. Install the O-ring (key 57) and handjackstem (key 56), turning the screw into the housingas far as possible. Place the O-ring (key 58) overthe housing and insert into the cylinder (key 1). Re-place the cap screws (key 60) and tighten to 30lbfft (41 Nm) on size 25 actuators or 60 lbfft (81

Nm) on size 50 actuators. Replace the jam nut(key 52), handwheel (key 47), and slotted nut andcotter pin (keys 72 and 73).

c. For Type 585CR actuators (figures 4 and 5),put the piston (key 3) on the actuator stem and thetravel stop spacer (key 5) on the piston. Apply Lu-briplate MAG-1 lubricant (key 24) or equivalent tothe threads of the piston cap screw or piston stud(key 4 or 69). Insert the piston cap screw, or studplus attached handwheel stem (key 56), through

both the travel stop spacer and piston and into theactuator stem. Use a wrench on the flats of the ac-tuator stem to prevent it from turning. Tighten thepiston cap screw, or stud plus attached handwheelstem, to 75 lbfft (102 Nm) for size 25 actuators or100 lbfft (136 Nm) for size 50 actuators. Centerthe inner bias spring, if used, (key 17 per table 2 or3) around the travel stop spacer. If used per table 2or 3, center the outer bias spring (key 16) aroundthe inner bias spring. The outer bias spring shouldbe within the outer boss on the piston.

11. Install the piston O-ring (key 8) if it was removed

from the piston, and the yoke O-ring (key 7, figure 2 or4) if it was removed from the yoke (key 6). Apply Lu-briplate MAG-1 lubricant (key 24) or equivalent to thewall of the cylinder (key 1) and carefully slide the cylin-der over the piston O-ring. Be sure the cylinder pres-sure connection is aligned with the yoke pressure con-nection. Square the cylinder in place over the yokeO-ring.

12. Line up the cylinder holes with the yoke holesmaking sure for a handwheel construction that theanti-rotation groove in the handwheel stem (key 56) isaligned with the hole in the cylinder for the anti-rotation

key (key 40).

Note

When placing the cylinder on the yokeand tightening the cylinder-to-yokebolts, be sure to keep the cylindersquare and aligned with the top of theyoke.

13. Lubricate the cylinder-to-yoke bolts (key 2) withLubriplate MAG-1 lubricant (key 24) or equivalent. In acriss cross pattern, alternately tighten each cylinder-to-yoke bolt a slight amount so that the cylinder stayssquare with the yoke. When all cylinder surfaces are incontact with the yoke, tighten each cylinder-to-yokebolt to 55 lbfft (70 Nm) for a size 25 or 70 lbfft (95Nm) for a size 50.

14. With a handwheel construction, performsteps 11. through 19. of the Replacing HandwheelHousing O-ring or Thrust Bearingsprocedure.

15. If the actuator will be mounted on a valve, performthe appropriate actuator mounting procedure. Other-

wise, place the stem connector nut (key 13), stemconnector (key 12), two cap screws (key 14), two hexnuts (key 23) and hex nut (key 15) in a parts bag andattach the bag to the actuator yoke.
