Description

The Type 1077 manual-only handwheel actuator (figure 1) is used with rotary-shaft valves such as the 9500 butterfly valve, Type 8532 and 8560 eccentric disc valves, Design V150, V200 and V300 Vee-Ball valves, Design V250 valves, and Design CV500 and V500 eccentric plug valves. In the Type 1077 actuator, torque is transmitted from the handwheel through the handwheel input shaft to a worm and drive sleeve gear (sector) with splined bore. The worm and drive sleeve gear multiply the torque and transmit it to a splined valve shaft or splined stub shaft. The size 10-KE:6 actuator additionally has a spur gear reduction drive for increased torque capability.

Specifications

Type 1077 actuator specifications are given in table 1. Some specifications for a given actuator as it comes from the factory are stamped on a metal nameplate attached to the actuator mounting yoke (key 7, figure 6).

Handwheel Rotation

Direct Acting Construction: Clockwise

handwheel rotation closes the valve (produces clockwise rotation of valve shaft) as shown in figure 2.

Installation

The Type 1077 actuator is normally shipped mounted on a control valve body. Follow the procedures in the control valve body instruction manual for valve installation. Then, proceed to the Operation section of this manual.

If the actuator has been shipped separately for installation on a valve body, or if the actuator was removed for maintenance, mount the actuator by following the instructions presented in this section before installing the valve body in the pipeline.

Individual part key numbers and part descriptions referenced in this procedure are shown in figure 6 and 7 except where otherwise indicated.

Reverse Acting Construction: Clockwise handwheel rotation closes the valve (produces counterclockwise rotation of valve shaft) as shown in figure 2.

Maximum Output Rotation

0 to 90 degrees.

Mounting Positions

J Right-hand (actuator on right side of valve body when viewed from the body inlet) or

J left-hand (actuator on left side of valve body when viewed from the body inlet). Position 1 as shown in figure 3 is standard; however, the actuator may be mounted in any of the positions shown in figure 3. Refer to figure 2 to determine the correct actuator construction.

Approximate Weights

See table 3

properly positioned, remove the gearbox cover plate. Use the appropriate view in figures 3, 4, and 5 to determine that the drive sleeve gear is at the proper end of its rotation.

1. Rotate the valve disc or ball to the closed position. Refer to the separate valve body instruction manual to determine the closed position. Consult the appropriate valve instruction manual Installation section for valve shaft orientation marks.

2. Rotate the handwheel (key 5) to move the drive sleeve gear to the position that is to correspond to the closed position of the valve disc or ball as follows:

For direct acting turn the handwheel so that the drive sleeve gear and travel indicator are rotated fully clockwise.

CAUTION

Rotating the valve disc or ball in the wrong direction will damage seals and other internal parts in some valve bodies. If the drive sleeve gear (key 1A) is not properly positioned, improper disc or ball rotation could result. If there is any doubt as to whether or not the drive sleeve gear is

For reverse acting turn the handwheel so that the drive sleeve gear and travel indicator are rotated fully counterclockwise.

3. Remove the travel indicator pointer by removing the machine screws. For a size 0-KE actuator only, remove the O-ring seal from the hub of the drive sleeve gear. Locate the four index marks on the drive sleeve gear hub. Also locate the index mark on the end of the valve shaft or stub shaft (key 13, figure 7).

4. Proceed as appropriate:

a. For valves with splined shafts, refer to figures 3, 4, and 5 and locate the correct view for the valve body and mounting position being used. When the actuator is installed, the valve shaft index mark must be aligned with the proper gear hub index mark.

b. For valves with keyed shafts, compare the position of the stub shaft keyway with the position of the connector (key 11, figure 7) keyway. Align the stub shaft index mark with the appropriate drive sleeve gear hub index mark such that the connector keyway will be in line with the valve shaft keyway.

5. Making certain that index mark alignment is correct, slide the actuator onto the valve shaft in the desired mounting position (figure 4 or 5). Check to be sure the valve shaft index mark is still aligned with the proper gear hub index mark.

6. Check the alignment of the mounting holes in the mounting yoke (key 2) with those in the valve body. If the holes are not aligned, rotate the handwheel to allow repositioning of the yoke. It may be necessary to loosen the hex nuts and back out the travel stop set screws (key 10) to allow this repositioning.

7. When hole alignment is correct, secure the mounting yoke to the valve body with washers (key 4) and the valve body cap screws (key 9).

10. Before installing the valve body and actuator in the pipeline, perform the procedures presented in the Adjustment section of this manual.

Adjustment

Perform the following steps to adjust the travel stops and the travel indicator pointer. Individual part key numbers and part descriptions referenced in this procedure are shown in figure 6 except where otherwise indicated.

8. If removed for inspection, install the gearbox cover plate. For a size 0-KE actuator only, also install the O-ring onto the hub of the drive sleeve gear.

9. Making certain that the travel indicator pointer is aligned as it was prior to disassembly, install the travel indicator.

Travel stops (key 10) consist of two set screws and two hex nuts. For 90-degree valve disc or ball rotation, both set screws are of equal length. For 60-degree disc or ball rotation, one set screw is longer than the other. To change from 90-degree to 60-degree disc or ball rotation, one set screw must be replaced with a longer one as explained below.

Note

Sizes 2-KE, 7-KE, 9-KE & 10-KE:6 use the same actuator for both 0–60 degrees and 0–90 degrees, with the replacement of the appropriate set screw. Sizes 0-KE & 6-KE require a different actuator when changing from 90-degree to 60-degree disc or ball rotation.

For Direct acting (except for 0-KE & 6-KE),

replace the set screw that limits counterclockwise drive sleeve gear and travel indicator rotation.

For Reverse acting (except for 0-KE & 6-KE),

replace the set screw that limits clockwise drive sleeve gear and travel indicator rotation.

Note

A 60-degree set screw used as an opening stop can limit valve ball or disc opening to any angle between 60 and 90 degrees. Alternately, it may be used as a closing stop to limit valve closing to any angle between 0 and 30 degrees. One or two 60-degree set screws may be used to extend the range of the valve opening stop, the valve closing stop, or both

1. If the valve body is in the line, remove it by following the instructions in the separate valve body instruction manual.

2. Loosen the hex nuts and back out both set screws.

3. Rotate the handwheel (key 5) to move the valve disc or ball to the fully closed position. Refer to the separate valve body instruction manual for instructions to determine the fully closed position of the disc or ball.

4. With the valve disc or ball closed, rotate the set screw that is to limit valve closing until this set screw just hits the drive sleeve gear. Lock the set screw with the hex nut.

5. Rotate the handwheel until the disc is at the desired maximum rotation as indicated by the pointer tip on the travel indicator dial. Rotate the remaining travel stop set screw until it just hits the drive sleeve gear. Lock the set screw with the hex nut.

6. Install the valve body and actuator in the pipeline by following the instructions in the separate valve

body instruction manual; then proceed to the Operation section.

Operation

Individual part key numbers and part descriptions referenced in this procedure are shown in figure 6 except where otherwise indicated.

After the travel stops (key 10) and travel indicator pointer have been adjusted and the control valve assembly installed, the actuator is ready for operation. The handwheel rotation direction required to open the valve is indicated on the face of the handwheel (key 5).

CAUTION

To avoid damage to the actuator, the valve shaft splines, and internal valve parts, do not exceed the maximum allowable torques listed in table 2 or any other torque limitation of internal valve parts. Also, do not use wrenches or other devices on the handwheel or handwheel shaft to increase operating force.

If the force required to rotate the handwheel will exceed the wheel-rim force listed in table 2, check for the following conditions:

D Insufficient lubrication,

D Seized actuator parts,

D Excessive pressure drop across the valve

body, or

D Obstruction to the valve body disc or ball

rotation.

Instructions are given in the Maintenance section for lubrication of actuator parts. Refer to the separate valve body instruction manual if valve body maintenance is required.

If the actuator does not seem to control the process fluid, worm or drive sleeve gear teeth may be broken, the pin (key 6) may be sheared, or internal valve body parts may be broken. Refer to the separate valve body instruction manual if valve body maintenance is required.

Maintenance

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations:

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

D Be sure the actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve. Drain the process media from both sides of the valve.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression.

D Use lockout procedures to be sure that the above measures stay in effect while you work on the equipment.

D 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.

Individual part key numbers and part descriptions referenced in the following procedures are shown in figure 6 except where otherwise indicated.

Lubrication

The interior parts of a Type 1077 actuator should be lubricated on a regular schedule with a quality gear lubricant. The interior parts should also be lubricated

whenever difficulty in handwheel rotation indicates a need for lubrication.

To lubricate the Type 1077 actuator, perform the following steps:

1. Note the location of the travel indicator pointer in relation to the indicator dial. When reassembling the actuator, the travel indicator pointer must be returned to its original position. Remove the machine screws and the travel indicator pointer.

2. For a size 0-KE actuator only, remove the O-ring grease seal from the hub of the drive sleeve gear.

3. Remove the cap screws which secure the gearbox cover plate and remove the gearbox cover plate.

4. Coat the worm, the drive sleeve gear teeth, and the bearing surfaces of the gearbox housing and worm with a quality gear lubricant.

5. Install the cover on the gearbox (key 1) and secure it with the cap screws.

6. For a size O-KE only, install the the O-ring grease seal onto the hub of the drive sleeve gear.

7. Attach the travel indicator pointer so that it indicates the same point of rotation as was noted before the pointer was removed. Secure the pointer with the machine screws.

Disassembly

Parts are subject to normal wear and must be inspected periodically. The following procedure describes actuator disassembly for general inspection and replacement of the drive sleeve gear.

Note

In order to remove the drive sleeve gear, it is necessary to first remove the actuator input shaft and worm.

1. Remove the pin (key 6) and the handwheel (key 5).

2. For a size 10-KE:6 actuator only, remove the cap screws which secure the reduction drive (item not shown) and slide the reduction drive off the input shaft.

3. Perform steps 1, 2, and 3 of the lubrication procedure above.

4. Remove the pin which secures the worm to the input shaft by following the appropriate procedure for the actuator size:

Instruction Manual

Form 5605 March 2007

1077 Actuator

For a size 0-KE or 2-KE actuator, drive the pin into the shaft (the pin length is less than the shaft diameter). Remove the input shaft from the actuator housing and drive the pin out of the shaft.

For a size 6-KE actuator, rotate the input shaft so that the pin may be driven through the soft plug (item not shown) on the back side of the gearbox housing.

For a size 7-KE, 9-KE, or 10-KE:6 actuator,

there is sufficient clearance in the gearbox housing to drive the pin through the shaft. Rotate the input shaft so that the pin will emerge on the drive sleeve gear side of the shaft and carefully drive the pin out of the shaft.

5. Remove the input shaft and push the worm away from the drive sleeve gear.

6. Carefully noting the position of the index marks on the drive sleeve gear hub, remove the drive sleeve gear.

7. Remove the worm gear along with any shims or thrust bearings where used.

8. Inspect all parts for excessive wear.

Assembly

Note

Before or during assembly, coat the following surfaces with a quality gear lubricant:

D The teeth of the worm and the

drive sleeve gear, and

D The bearing surfaces of the gearbox housing, worm and input shaft.

1. Install the worm and any shims and thrust bearings into the gearbox casing. Keep the worm at the maximum possible distance from the installed position of the drive sleeve gear.

2. Install the drive sleeve gear onto the splined valve shaft. Be sure that the index marks are aligned as they were prior to disassembly.

3. Noting the position of the pin holes and the original position of all shims and thrust bearings, install the actuator input shaft into the bore of the worm.

4. Make sure that the pin holes are aligned and install the worm pin. Be certain that the pin does not protrude from either side of the worm and interfere with the teeth on the drive sleeve gear.

For a size 6-KE actuator only, install the soft plug on the back side of the gearbox (key 1) housing.

5. Install the gearbox cover plate.

6. For a size 0-KE actuator only, install the O-ring grease seal onto the hub of the drive sleeve gear.

7. Install the travel indicator making certain that the pointer indicates the same degree of rotation as was noted prior to disassembly.

8. For a 10-KE:6 actuator only, install the reduction drive onto the input shaft and secure with capscrews.

9. Install the handwheel (key 5) and pin (key 6).
