Instruction Manual

D102087X012 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

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.

X–Indicates where the listed supply pressure will exceed the maximum thrust allowable.

1. The maximum design pressure for size 25 through 100 actuators is 10.3 bar (150 psig). The size 68 and 130 actuators are limited to 9.7 and 7.8 bar (140 and 113 psig) respectively.

2. The size 25 and 50 data is for the construction without a bias spring.

3. Minimum operating pressure for sizes 60-130 actuators is 2.4 bar (35 psig).

4. The size 68 actuator with a handwheel is limited to 40000 Newtons (9000 lb) thrust.

Principle of Operation

The 585C piston actuator (figures 2 and 3) uses a piston that moves inside the actuator cylinder. An O-ring (see figure

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 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 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

Instruction Manual

D102087X012

585C Actuator

October 2013 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 66 for sizes 25 and 50, figure 8; key 92 for sizes

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.

Actuator Mounting

Size 25 and 50 Actuator Mounting

The following procedure describes how to mount a 585C actuator size 25 and 50 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 4 through 8.

585C Actuator

October 2013

Instruction Manual

D102087X012

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 of the valve stem threads.

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

4. Place the actuator on the bonnet of the valve and secure the actuator tightly to the bonnet with the yoke locknut.

CAUTION

In the following procedure, do not rotate the valve plug while it is seated since this may cause damage to the seating surface and thereby allow excessive leakage. Also, during adjustment, use tools carefully to avoid damaging the valve plug stem. A damaged valve plug stem could cut the packing and allow leakage.

Note

When using an actuator with handwheel in the following step to stroke the valve plug, be sure the bypass valve (key 66, figure 5, 7, or 8) is open. Rotating the handwheel (key 47, figure 5, 7, or 8) clockwise extends the actuator stem (key 10); rotating the handwheel counterclockwise retracts the actuator stem.

5. Perform one of the following procedures (a or b as appropriate): a. For a 585C actuator with spring retraction upon loss of cylinder pressure (figures 4 and 5) on a push-down-to-close valve, manually move the valve plug to the seated position. Rotate the handwheel or apply pressure to the pressure connection in the cylinder (key 1) until the piston (key 3) and actuator stem (key 10) move down the specified travel. Run the stem connector nut (key 13) up on the valve stem until it contacts the actuator stem. Be sure the flats on the actuator stem are perpendicular to the scale indicator web on the yoke

(key 6). Adjust the stem connector nut as necessary, so that the flats on the nut and the actuator stem are parallel. Clamp the actuator stem and stem connector nut together with the stem connector (key 12) and the two cap screws and hex nuts (keys 14 and 23). Run the hex nut (key 15) up the valve stem and tighten against the stem connector nut (key 13).

b. For a 585C actuator with spring extension upon loss of cylinder pressure (figures 6 and 7) with push-down-to-close valve, manually move the valve plug to the seated position. Run the stem connector nut

(key 13) up the valve stem until it contacts the actuator stem (key 10). Rotate the handwheel or apply pressure to the pressure connection in the yoke (key 6) to move the actuator stem (key 10) approximately 1/4 inch away from the stem connector nut. Rotate the stem connector nut so that it moves up the valve stem two full turns.

Manually move the valve plug so that the stem connector nut again contacts the actuator stem. Be sure the flats on the actuator stem are perpendicular to the scale indicator web on the yoke (key 6). Adjust the stem connector nut, as necessary, so that the flats on the nut and the actuator stem are parallel. Clamp the actuator stem and stem connector nut together with the stem connector (key 12) and the two cap screws and hex nuts (keys 14 and 23). Run the hex nut (key 15) up the valve stem and tighten it against the stem connector nut (key 13).

6. Cycle the actuator several times to check for proper operation.

Note

In the following step, make sure the correct travel indicator scale (key 19) is used per the Parts List for the desired travel.

7. If necessary, remove the travel indicator scale screws (key 18) and reposition the travel indicator scale (key 19) so that the scale arrow points in the same direction as the valve plug moves when opening. Close the valve. Adjust the scale up or down so that the stem connector (key 12) indicator lines up with the closed mark on the scale. Secure the scale with the scale screws.

585C Actuator

October 2013

Size 60-130 Actuator Mounting

The following procedure describes how to mount a 585C size 60 to 130 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 9 through 12.

If an actuator is purchased separately for field installation on a control valve, mount it on the valve and secure it in place with the yoke locknut for size 60 and 68 or with eight bolts on actuator sizes 80, 100, and 130 which use a 127 mm (5-inch) yoke boss.

The stem connector should then be set up to clamp the actuator stem and valve plug stem together to provide the proper valve travel. This procedure is outlined in the Stem Connector Assembly procedures of this instruction manual.

Stem Connector Assembly (Size 60-130)

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.

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. Incomplete engagement of valve stem and/or actuator stem in the stem connector can result in stripped threads or improper operation. Be sure that the length of each stem clamped in the stem connector is equal to or greater than the diameter of that stem. Do not loosen the cap screws when the stem connector has spring or loading pressure force applied to it.

Install the stem connector securely before a positioner is mounted to the actuator and pressurized, using only a regulator- controlled air supply, not the positioner, to move the actuator piston to position the actuator stem.

To avoid personal injury or property damage, keep hands and tools out of the actuator stem travel path while pressuring the actuator to move the actuator stem in the following steps.

585C Size 60-130 Direct-Acting (Push-Down-to-Close) Valves

1. With the valve assembled and the actuator mounted, make sure the valve plug is in the closed position, and the actuator is at the top of its stroke. Then screw the two stem locknuts (key 15) all the way onto the stem thread and place the travel indicator disk (key 32) (if any) on the stem locknuts.

2. Keeping your hands away from any moving parts, use a regulator-controlled air supply to move the actuator stem

(key 10) down from the top of its stroke to the specified valve travel.

3. Using one half of the stem connector (key 12), align the actuator stem and the valve stem with threads from both stems mated root-to-crest with the stem connector. Install the other half of the stem connector and tighten the cap screws. With the stem locknuts (key 15), raise the travel indicator disk (key 32) to the stem connector (key 12).

4. Cycle the actuator to check availability of desired total travel and that the valve plug seats before the actuator contacts the lower travel stop. Minor travel adjustments can be made by loosening the stem connector (key 12) slightly, tightening the locknuts (key 15) together, and screwing the valve stem either into or out of the stem connector (key 12) with a wrench on the locknuts (key 15). If the valve stem cannot be turned, as with a bellows seal bonnet, remake the stem connection to achieve the desired travel.

585C Actuator

October 2013

Instruction Manual

D102087X012

5. Once the total travel is adequate, tighten the stem connector (key 12) securely, lock the stem locknuts (key 15) against the connector, and adjust the indicator scale (key 19) on the yoke to show correct valve plug position.

6. Provide a gauge to measure the pressure to the actuator. Make a final adjustment of the actuator or its positioner to set the starting point of valve travel and to obtain full travel for the given instrument range.

585C Size 60-130 Reverse-Acting (Push-Down-to-Open) Valves

1. Keeping your hands away from moving parts, pressure the actuator, using a regulator-controlled air supply, to move the actuator stem (key 10) to the extreme upward position then reverse loading pressure to lower the actuator stem (key 10) approximately 3 mm (1/8 inch).

2. Pull the valve stem up to seat the valve plug.

4. If there is a travel indicator disk (key 32), raise it to the stem connector (key 12) and tighten in position with the stem locknuts (key 15). The indicator disk (key 32) should show the valve to be open with the piston (key 3) at the bottom of its stroke. If it does not, loosen two screws (key 18) and shift the travel indicator scale (key 19) to indicate

OPEN.

5. Cycle the actuator to check availability of desired total travel and that the valve plug seats before the actuator contacts the upper travel stop. Minor travel adjustments can be made by loosening the stem connector (key 12) slightly, tightening the locknuts (key 15) together, and screwing the valve stem either into or out of the stem connector (key 12) with a wrench on the locknuts. If the valve stem cannot be turned, as with a bellows seal bonnet, remake the stem connection to achieve the desired travel.

6. Once the total travel is adequate, tighten the stem connector (key 12) securely, lock the stem locknuts (key 15) against the connector, and adjust the indicator scale (key 19) on the yoke to show correct valve plug position.

7. Provide a gauge to measure the pressure to the actuator. Make a final adjustment of the actuator or its positioner to set the starting point of valve travel and to obtain full travel for the given instrument range.

585C Handwheels

Handwheel Operation (Sizes 25 & 50)

Key numbers referenced in the following steps are shown in figures 5, 7, and 8 for the 585C actuator.

The handwheel assembly on a 585C actuator may be used as an adjustable travel stop to limit full upward or downward travel of the actuator stem (key 10), or as a manual actuator to fully stroke the valve. When the neutral indicator (key 42) is in the neutral position, travel is not restricted. With clockwise handwheel (key 47) rotation, the operating nut (key 46) is screwed downward, forcing the actuator stem (key 10) down. With counterclockwise rotation, the operating nut is screwed upward against the handwheel stem washer (key 45), pulling the actuator stem up.

Note

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

Handwheel Operation (Sizes 60-130)

The 585C handwheel assembly for sizes 60 through 130 actuators (figures 9 and 10) has three main functions:

Instruction Manual

D102087X012

585C Actuator

October 2013 a. To open or close the valve manually or to position the valve at any point in the stroke, regardless of the cylinder pressure. The tapered pin is inserted during manual throttling operation.

b. To act as a travel stop to limit full opening or closing of the valve but not both at the same time. The tapered pin is left out when the assembly is used as a travel stop.

c. To open or close the valve manually in an emergency without the necessity of inserting the tapered pin.

Bevel gears are used in sizes 60 and 68 and worm gears in sizes 80 through 130. A spring-loaded ball detent is provided in the handwheel to prevent a change in setting due to vibration. The following table 10 lists pertinent information on these handwheel units.

Table 10. Handwheel Information

Maintenance (Sizes 25 & 50)

Actuator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends on the severity of service conditions. This section provides two separate procedures, one on Replacing Handwheel Housing O-Ring or Thrust Bearings, and the other on Replacing Seals,

Changing Action, or Changing Bias Spring(s).

Refer to figures 5 and 7.

For an actuator with handwheel, a grease fitting (key 50) is provided on the bearing cover (key 38) for periodic bearing lubrication with lithium grease (key 24).

WARNING

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

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

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

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.

Use 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.

Vent the power actuator loading pressure and release all bias spring compression force by slowly unscrewing the cylinder cover bolting in a crisscross pattern.

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

The 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.

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

2. To achieve the desired construction (either a direct-acting or a reverse-acting 585C actuator), perform one of the following assembly procedures (a, b, or c, as appropriate): a. For 585C actuators (bias spring retracts the piston rod) (figures 4 and 5), center the inner bias spring, if used,

(key 17 per table 6 or 7) around the center boss in the yoke (key 6). If used per table 6 or 7, center the outer bias spring (key 16) around the inner bias spring. The outer bias spring should be within the outer boss in the yoke.

Put the travel stop spacer and the piston (keys 5 and 3) on the actuator stem. Apply lithium grease (key 24) to the threads of the piston cap screw or piston stud (key 4 or 69). Insert the piston cap screw, or stud plus attached handwheel stem (key 56), through both the piston and travel stop spacer and into the actuator stem. Use a wrench on the flats of the actuator stem to prevent it from turning. Tighten the piston cap screw, or stud plus attached handwheel stem, to 102 NSm (75 lbfSft) for size 25 actuators or 136 NSm (100 lbfSft) for size 50 actuators.

b. For 585C actuators with push-only handwheel (figure 8), lubricate the O-rings and handjack stem threads with lithium grease. Install the O-ring (key 57) and handjack stem (key 56), turning the screw into the housing as far as possible. Place the O-ring (key 58) over the housing and insert into the cylinder (key 1). Replace the cap screws

(key 60) and tighten to 41 NSm (30 lbfSft) on size 25 actuators or 81 NSm (60 lbfSft) on size 50 actuators. Replace the jam nut (key 52), handwheel (key 47), and slotted nut and cotter pin (keys 72 and 73).

c. For 585C actuators (bias spring extends the piston rod) (figures 6 and 7), put the piston (key 3) on the actuator stem and the travel stop spacer (key 5) on the piston. Apply lithium grease (key 24) to the threads of the piston cap screw or piston stud (key 4 or 69). Insert the piston cap screw, or stud plus attached handwheel stem (key

56), through both the travel stop spacer and piston and into the actuator stem. Use a wrench on the flats of the actuator stem to prevent it from turning. Tighten the piston cap screw, or stud plus attached handwheel stem, to 102 NSm (75 lbfSft) for size 25 actuators or 136 NSm (100 lbfSft) for size 50 actuators. Center the inner bias spring, if used, (key 17 per table 4 or 5) around the travel stop spacer. If used per table 4 or 5, center the outer bias spring (key 16) around the inner bias spring. The outer bias spring should be within the outer boss on the piston.

3. Install the piston O-ring (key 8) if it was removed from the piston, and the yoke O-ring (key 7, figure 4 or 6) if it was removed from the yoke (key 6). Apply lithium grease (key 24) to the wall of the cylinder (key 1) and carefully slide the cylinder over the piston O-ring. Be sure the cylinder pressure connection is aligned with the yoke pressure connection. Square the cylinder in place over the yoke O-ring.

4. Line up the cylinder holes with the yoke holes making sure for a handwheel construction that the anti-rotation groove in the handwheel stem (key 56) is aligned with the hole in the cylinder for the anti-rotation key (key 40).

Note

When placing the cylinder on the yoke and tightening the cylinder-to-yoke bolts, be sure to keep the cylinder square and aligned with the top of the yoke.

5. Lubricate the cylinder-to-yoke bolts (key 2) with lithium grease (key 24). In a criss cross pattern, alternately tighten each cylinder-to-yoke bolt a slight amount so that the cylinder stays square with the yoke. When all cylinder surfaces are in contact with the yoke, tighten each cylinder-to-yoke bolt to 70 NSm (55 lbfSft) for a size 25 or 95

NSm (70 lbfSft) for a size 50.

6. With a handwheel construction, perform steps 2. through 10. of the Replacing Handwheel Housing O-ring or

Thrust Bearings procedure.

7. If the actuator will be mounted on a valve, perform the appropriate actuator mounting procedure. Otherwise, place the stem connector nut (key 13), stem connector (key 12), two cap screws (key 14), two hex nuts (key 23) and hex nut (key 15) in a parts bag and attach the bag to the actuator yoke.

Maintenance (Sizes 60-130)

WARNING

Avoid personal injury from sudden release of process pressure or uncontrolled process fluid. Before starting disassembly:

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

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

Disconnect any operating lines providing air pressure to the actuator. Be sure the actuator cannot suddenly open or close the valve.

D Vent the power actuator loading pressure.

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

The 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.

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

Key numbers indicated refer to figures 9 through 12.

1. If positioner is not used, go to step 5. If positioner is used, shut off all pressure lines to the positioner then remove all tubing lines (cylinder, instrument and supply) from the positioner.

CAUTION

Do not use wrenches or other tools directly on the valve stem. Damage to the stem surface could result in subsequent damage to the valve packing.

2. Remove the stem connector (key 12) and the piston rod boot (key 29) used to protect the lower end of the actuator stem.

3. Remove the socket head cap screws that hold the cylinder (key 1) to the yoke (key 6).

4. Insert a screwdriver in the two slots on the lower edge of the cylinder casting and pry the cylinder loose from the yoke. Remove the cylinder, being careful not to mar the cylinder wall.

5. The piston (key 3) and actuator stem (key 10) will come out with the cylinder. The piston can then be removed by forcing it out the open end of the cylinder.

6. Unscrew the seal bushing (key 110 or 26), in the upper end of the yoke (key 6).

7. With the unit disassembled, inspect all parts for excessive wear. Replace all worn O-rings. Lubricate (key 24) as indicated on the assembly drawings. Apply sealant (key 70) as indicated on the assembly drawings.

8. When reassembling the actuator after the piston nut (key 4) has been removed from the actuator stem (key 10), clean the threads of the piston nut thoroughly and apply thread sealant to the threads. Tighten the piston nut securely to a torque of 237 NSm (175 lbfSft) for size 60 actuators, 1290 NSm (950 lbfSft) for size 68, 80, and 100 actuators, or 2070 NSm (1530 lbfSft) for size 130 actuators.

Side-Mounted Handwheel Maintenance (Sizes 60-130)

Refer to figure 9 and 10.

1. The handwheel gears should be lubricated periodically. A grease fitting (key 140) is provided on sizes 80, 100, and

130. On sizes 60 and 68, remove the handwheel (key 118) and the bevel pinion (key 116) and pack the gear case with lithium grease. Loosen the set screw (key 139) before attempting to remove the pinion and extension.

2. If it is necessary to change the valve plug action from push-down-to-close to push-down-to-open or vice versa, change the handwheel arrangement so that the arrow indicates the correct rotation required to open the valve.

a. For sizes 60 and 68, remove the handwheel, invert and replace it. On sizes 60 and 68 (figure 9), remove and replace the spring-loaded ball assembly (key 123) in the opposite side.

b. For sizes 80-100, remove the handwheel assembly and install in the opposite end of the gear case by unscrewing the back and front worm retainers (keys 135 and 136, not shown) and turn the handwheel to disengage the bevel pinion (key 116).
