INTRODUCTION:
Thank you for selecting Sharpe Valves for your valve or damper automation requirement. We at Sharpe
Valves are proud of our products and feel confident they will meet or exceed your expectations of quality
and reliability.

Every precaution has been taken to insure that your equipment will arrive undamaged; however, accidents
do occur. Therefore, the first thing you must do upon receipt of your package is to inspect it for damage. If
the box is damaged there is a possibility that the equipment inside the box may be damaged as well. If this
is the case
YOU MUST FILE A CLAIM
with the delivering
CARRIER
. All shipments are
F.O.B.
our
factory and it is
YOUR RESPONSIBILITY
to file a claim for damages.

STORAGE:

If the actuators are scheduled for installation at a latter date:
1.
Store off the floor.
2.
Store in a climate controlled building.
3.
Store in a clean and dry area.

INSTALLATION:

The actuator is shipped in the open position from the factory, it is important to make sure the valve and
actuator are in the same position before mounting the actuator on the valve.

1.
Manually open valve.
2.
Remove valve mechanical stops.
CAUTION:
DO NOT REMOVE any parts necessary for the

proper operation of the valve, i.e., packing gland, gland nut, etc.
3.
Check again that the valve and actuator are in the same position.
4.
Install mounting hardware on valve, do not tighten bolts securely at this time, mount actuator to
valve, once actuator screws have been started securely tighten all nuts and bolts. NOTE: Actuator
conduit entry is normally positioned perpendicular to pipe line.
5.
Remove actuator cover.
6.
Wire actuator using the wiring diagram inside cover.
CAUTION:
Be sure power is off at the main
power
box.
7.
Turn on power to actuator.
CAUTION:
Use extreme caution, as there are live circuits that could
cause electrical shock or death.
8.
Operate the valve to the close position, check the alignment.
9.
Operate the valve to the open position, check the alignment.
10.
Replace cover and secure cover screws.


CALIBRATION:

After checking the alignment of the valve port calibration may be required.

To set the open position:
1.
Operate valve to the open position by applying power to terminal connections #1 and #2, the valve

will rotate counter clockwise, CCW, viewing top of actuator. NOTE: When the actuator is in the

open position the setscrew securing the cam to the shaft will be easily accessible.

1a.
If valve did not open completely;


1aa.
Loosen 8-32 set screw in top cam.


2aa.
Rotate cam clockwise (CW) until the switch makes contact, listen carefully for a


slight click. The valve will begin to rotate CCW, by making small incremental CW


movements of the cam the valve can be positioned precisely in the desired position.


3aa.
Securely tighten the setscrew.

1b.
If valve traveled too far.
CAUTION:
Valves with mechanical stops may be damaged or



cause damage to the actuator if allowed to travel too far.


1bb. Apply power to terminal connections #1 and #3, the valve will begin to rotate CW,



allow it to travel to the mid position.


2bb. Follow directions in 1a of To set open position.








To set close position:
1.
Operate valve to the close position by applying power to terminal connections #1 and #3, the valve

will rotate CW viewing the top of the actuator. NOTE: When the actuator is in the close position

the setscrew securing the close cam to the shaft will be easily accessible.

1a.
If valve did not close completely;


1aa.
Loosen 8-32 set screw in bottom cam.
2aa.
Rotate cam CCW until the switch makes contact, listen for a slight click. The valve
will begin to rotate CW, by making small CCW incremental movements of the cam
the valve can be positioned precisely in the close position.


3aa.
Securely tighten the setscrew.
To set close position, continued:

1b.
If the valve has traveled too far closed.
CAUTION:
Valves with mechanical stops may be


damaged or cause damage to the actuator if allowed to travel too far closed.


1bb. Apply power to terminal connection #1 and #2, the valve will begin to




rotate CCW, allow to rotate to the mid position.


2bb. Follow directions in 1a. of To set close position.
