1Storage Instructions
Section 1: Storage Instructions
1.1 Short Term Storage
(Stored at job site less than one year from shipment)
1. Actuator should be stored in the recommended mounting position. The motor
should be horizontal and Electrical Enclosure either horizontal or vertical.
Figure 1
2. Actuator should be stored indoors free from job site dirt, mud, moisture and
temperature changes.
3. If indoor storage is not possible, the actuator must be stored off the ground, above
possible water or snow level. Remove MCP and store with other electrical and
electronic equipment in protected warehouse. If MCP is not removed,
Space Heater MUST be energized to protect Electrical and Electronic Controls.
4. Bettis supplies plugs in each conduit entry. Do not remove until electrical hook-up.
5. Cover units loosely with a plastic sheet. This serves as partial protection from rain.
1.2 Long Term Storage
(Stored more than one year from shipment)
1. Store indoors or MCP must be removed and stored in protected area. Follow
procedures of short term storage.
WARNING
Failure to store actuator properly will void warranty of electrical & electronic components.

2Storage Instructions
1.3 Do
1. Do follow proper storage procedures. Improper storage will void warranty.
2. DANGER: Do check for proper motor rotation. If valve goes wrong direction when
button is pushed, you have no torque or limit protection.
Either incoming power or motor wiring must be reversed.
3. Do read and follow procedures before attempting to energize actuator.
4. Do cut off electric power before opening switch compartment.
5. Do install pressure relief vent in highest point of gearbox.
6. Do use stem covers of sufcient length to protect valve stem.
7. Do clean Electrical Enclosure ange thoroughly & lightly grease before closing.
8. Do secure all Electrical bolts.
9. Do follow an annual maintenance procedure.
10. Do use caution when working on, with, or around valves and actuators. You are
dealing with high pressures, forces, voltages and ammable or toxic media.
1.4 Don't
1. Start-up without reading this manual.
2. Don’t stack actuators.
3. Don’t store actuator on the ground unprotected.
4. Don’t lift the unit by clutch lever or handwheel.
5. Don’t lift a valve assembly by electric actuator.
6. Don’t operate electrically without rst checking for proper phase rotation, valve
position, torque and limit switch adjustments.
7. Don’t plug the motor by starting and stopping repeatedly to move a valve that is
too stiff. Check for cause.
8. Don’t jumper torque switches except as recommended by Wiring Diagram or
Valve Manufacturer.
9. Don’t use oversize thermal motor overloads to eliminate a tripping problem.
Find the cause and correct.
10. Don’t use a cheater to try to force the handwheel. You can damage gearing and
shafting. Find the cause and correct.
11. Don’t torque seat valve, sluice gate or damper unless the valve manufacturer
recommends.
1.5 Lubrication
Bettis Actuators are factory lled with a high quality lubricant carefully selected to insure
actuator performance under specied operating conditions. Refer to Bettis JOB SPEC
SHEET to identify the lubricant provided. Normal operation of actuator will not require
replacement of lubricant.

3Storage Instructions
1.6 Maintenance
At least once a year a check should be made of your Bettis actuator.
a. Disconnect all electrical power to actuator.
b. Open Electrical Enclosure. Inspect and tighten all electrical connections.
c. Visually inspect for any electrical or mechanical damage.
Replace worn or damaged components.
d. Check lubrication consistency and level. Fill or replace if required.
1.7 Pressure Relief
During normal operation of Electric Actuator, gear temperature increase in combination
with outdoor temperature variations will cause a small pressure build-up.
Bettis furnishes a Pressure Relief Vent Fitting P/N 83385. Placement on Actuator can be
determined only after eld location and position of valve has been determined.
Select the highest 1/2 NPT vent location in the Gear Box, remove 1/2 NPT Plug and replace
with P/N 83385. Possible locations of the Plugs are shown on Bettis Outline Drawing.

Section 2: Assembly to Valves
2.1 Threaded Valve Stem
Figure 2 Stem Nut Installation (Multi-Turn)
1. Unscrew Locknut (55) holding Bronze Stem Nut (54) and remove Stem Nut and
Key (52).
2. Lubricate Stem and run Stem Nut down Stem to check acme thread t, then
remove Stem Nut and set aside.
3. Lower actuator over Stem onto valve ange. The screws thru valve ange into
actuator must engage a minimum of one full screw diameter deep into bottom
base and be tightened to a preload. See assembly drawing for screw size and
torque to tighten properly.
4. Screw Stem Nut on Valve Stem until it enters Drive Sleeve. Line Nut Key with Drive
Sleeve keyway and insert Stem Nut Key (52).
5. Turn handwheel in Open direction, pulling the Stem Nut into Drive Sleeve until it
bottoms out (valve will begin to open).
CAUTION
Locknut must be tight against stem nut.
6. Lower Locknut (55) over Valve Stem and screw into place rmly against top of
Stem Nut. Tap Locknut ears using brass drift.

5Assembly to Valves
2.1.0.1 Mounting Screws
If Bettis supplied adaption, the mounting screws are included. If the adaption to the valve
was the responsibility of others, the mounting screws are not furnished by Bettis. Screws
thru adapter MUST engage a minimum of one screw diameter deep into Bettis actuator
base.
2.1.0.2 Locknut Lockpin Installation
1. With the actuator in place on the valve, ensure proper ange mating and valve
actuator orientation.
2. Use a number 30 (.1285) drill bit to drill a hole 3/4 inch deep into the Drive Sleeve
assembly threads for the Locknut Lockpin(56). Use the groove in the Stem Nut
Locknut threads as a guide.
3. Install the Locknut Lockpin (56) into the drilled hole to prevent the Stem Nut
Locknut from working loose and turning.
NOTE:
When installing, the Locknut Lockpin should extend 1/4 inch above the Drive Sleeve
assembly to allow for easy removal.
2.1.1 Thrust Spool Installation (Multi-Turn)
1. Locate Thrust Mounting bolts.
2. Remove the eight mounting bolts and separate the Spool from the actuator.
3. Position the Spool over the Valve Stem. Thread the Spool onto the Valve Stem until
it meets the valve plate.
4. Bolt and secure the Spool onto valve.
5. Position actuator above Spool. Lower actuator onto Spool while manually rotating
the unit until ears on the Stem Nut and ears on the main Drive Sleeve mesh.
6. Grease the ange face before securing unit to Spool.
7. Re-install thrust plate mounting bolts. Tighten to proper torque.
NOTE:
Reverse procedure if the Stem Nut needs to be replaced. Actuator does not need to be
returned to factory for this procedure.

6Assembly to Valves
2.1.2 Spline Bushing (Quarter-Turn)
Bettis removable Spline Bushing allows easy adaption to valve shaft diameter and Key.
Actuator may be rotated with respect to the valve shaft for unexpected or awkward eld
installations.
1. Move valve to full Open or Close.
2. Place Spline Bushing on valve shaft with Key and tighten set screw.
3. Using the handwheel on actuator, move the Gear Position Indicator Arrow (21)
to full Open or Close (duplicating the position in Step 1).
4. Position actuator so the spline bore is correctly aligned with the Spline Bushing
on stem shaft.
5. Move the actuator onto the shaft until the ange faces properly mate.
Secure with screws thru the adapter ange into the base of the actuator.
2.2 Quarter Turn Valve
2.2.1 Stop Setting Procedure (Quarter-Turn)
Built-in mechanical stops are provided to prevent handwheel operation beyond total
valve travel (90° ± 6°).
Positive mechanical stops are in full accordance with AWWA 250% rim pull overload
requirement. End of travel stops are independently adjusted, locked in place and sealed.
