Inspection
Your manual actuator has been packaged to provide protection during shipment. Carefully inspect
the unit for damage upon arrival and file a claim with the carrier if damage is apparent.
Parts
Recommended spare parts are listed on the assembly drawing. These parts should be stocked to
minimize downtime.
Order parts from your DeZURIK sales representative, or directly from DeZURIK. When ordering
parts, please include the 7-digit part number and 4-digit revision number (example: 9999999R000)
located on the data plate attached to the valve assembly. Also include the part name, the assembly
drawing number, the balloon number and the quantity stated on the assembly drawing.

Manual Actuator for KSL Slurry Valves
WARNING!
Personnel involved in the installation or maintenance of valves should be con-
stantly alert to potential emission of process material and take appropriate
safety precautions. Always wear suitable protection when dealing with hazard-
ous process materials. Handle valves which have been removed from service
with the assumption of process material within the valve.

Operation
Handwheel, Chainwheel and Bevel-Gear Actuators
Rotate the handwheel or chainwheel clockwise to close the valve.
Note: There is an arrow cast on the wheel to indicate direction of rotation.
Removing Actuator
1. Close the valve.
2. Disconnect the stem from the gate by removing the two screws and nuts.
3. Remove the screws securing the legs to the valve, then separate the actuator from the valve.
Actuator Installation
1. Close the valve.
2. Set the actuator on the valve and secure it in place with the screws.
3. Connect the stem to the gate with two screws and nuts.
Mounting Handwheel on 2-6” Valves
2–6" Valves—See Figure 2
Two coiled springpins (B18) provided by DeZURIK are used to connect the handwheel (B11) to the
yoke sleeve (B3). The use of any other type of pin will result in actuator failure.
1. Rotate the yoke sleeve (B3) until the flange on the yoke sleeve touches the adaptor plate (B2).
2. Place the thrust washer (B4) and the wave washer (B5) over the yoke sleeve (B3) so they are on
top of the adaptor plate (B2).
3. Set the handwheel (B11) in place. Turn the handwheel so the holes in the handwheel line up with
the pin grooves in the yoke sleeve (B3).
4. Insert a 5/16"-diameter bolt in one of the holes.
Note: This will prevent misalignment. If the holes are not aligned with the pin grooves in the yoke
sleeve, it could be damaged by the coiled spring pins (B18) provided by DeZURIK.
5. Drive a coiled spring pin (B18) provided by DeZURIK into the remaining hole in the handwheel
(B11) until the end of the pin is flush with the outer surface of the handwheel.
6. Remove the 5/16" bolt installed in Step 4, and drive a coiled spring pin (B18) provided by
DeZURIK into the hole.
7. Install top stop collar (B8) onto stem and secure position with set screws (B23). This stop collar is
to stop on top of the yoke sleeve (B3) when the valve is in the closed position. Refer to installation
drawing for gate closed measurement.
8. Lubricate the actuator as described in the LUBRICATION section of these instructions.

FIGURE 1– Pin Designs
WARNING!
This actuator has been designed to use
only heavy-duty coiled spring pin pro-
vided by DeZURIK. The use of any other
brand or type of pin will result in actuator
failure. See Figure 1.

Mounting Chainwheel on 2-6” Valves
2–6” Valves—See Figure 2
Two coiled spring pins (B18) provided by DeZURIK are used to connect the chainwheel (B12) to the
yoke sleeve (B3). The use of any other type of pin will result in actuator failure.
1. Rotate the yoke sleeve (B3) until the flange on the yoke sleeve touches the bottom of the adaptor
plate (B2).
2. Place the thrust washer (B4) and the wave washer (B5) over the yoke sleeve (B3) so they are on
top of the adaptor plate (B2).
3. Set the chainwheel (B12) in place. Turn the chainwheel so the holes in the chainwheel line up with
the pin grooves in the yoke sleeve (B3).
4. Insert a 5/16"-diameter bolt in one of the holes.
Note: This will prevent misalignment. If the holes are not aligned the pin grooves in the yoke sleeve
(B3) could be damaged by the coiled spring pins (B18) provided by DeZURIK.
5. Drive a coiled spring pin (B18) provided by DeZURIK into the remaining hole in the chainwheel
(B12) until the end of the pin is flush with the outer surface of the chainwheel.
6. Remove the 5/16" bolt installed in Step 4, and drive a coiled spring pin (B18) provided by
DeZURIK into the hole.
7. Install top stop collar (B8) onto stem (B6) and secure position with set screws (B23). This stop
collar (B8) is to stop on top of the yoke sleeve (B3) when the valve is in the closed position. Refer
to installation drawing for gate closed measurement.
8. Insert the large hex-head retaining bolt (B33) through the 2.5-inch retaining washer (B32) and
stake the washer to the head of the bolt. This keeps the washer from sliding down the shaft of the
bolt when the valve is open (when the stem is extended upward).
9. Turn the 3/8-16 jam nut (B34) onto the retaining bolt/washer assembly. Turn the nut on far enough
to allow the bolt to be fully inserted into the valve stem (detailed in the next step).
10. Turn the retaining bolt assembly into the tapped hole on the valve stem until it bottoms out.
11. Tighten the jam nut firmly against the valve stem. This prevents the retaining bolt assembly (and
the chainwheel) from being dislodged if the two coiled spring pins provided by DeZURIK are
damaged or fatigued.
12. Lubricate the actuator as described in the LUBRICATION section of these instructions.
WARNING!
This actuator has been designed to use only coiled spring pins provided by
DeZURIK. The use of any other brand or type of pin will result in actuator failure.
See Figure 1.

Mounting Handwheel or Chainwheel on 8-10” Valves
8-10” Valves—See Figure 3
1. Rotate the yoke sleeve (B3) until the flange on the yoke sleeve touches the adaptor plate (B2).
2. Place the thrust washer(B4) over the yoke sleeve (B3).
3. Install the woodruff key (B24)in the yoke sleeve (B3) keyseat.
4. Align the keyway in the wheel with the key in the yoke sleeve (B3), then slide the wheel into the
yoke sleeve until the wheel contacts the shoulder on the yoke sleeve.
5. On valves with a chainwheel actuator, slide the chain guide (B13) over the yoke sleeve (B3) so the
guide loops are directly under the chainwheel (B12).
6. Screw the nut (B5) onto the yoke sleeve (B3) to retain the wheel.
7. Lock the nut (B5) to the yoke sleeve (B3) with set screw (B23)
8. Install top stop collar (B8) onto stem (B6) and secure position with set screws (B23). This stop col-
lar (B8) is to stop on top of the yoke sleeve (B3) when the valve is in the closed position. Refer to
installation drawing for gate closed measurement.
