ELECTRIC ACTUATORS
Electric Installation
1. Operate valve manually and place in the open position.
2. Remove any mechanical stops the valve might have. (DO NOT REMOVE ANY
PARTS NECESSARY FOR THE PROPER OPERATION OF THE VALVE, SUCH
AS THE PACKING GLAND, PACKING NUT, ETC.)
3. Ensure that the actuator output shaft and valve stem are aligned properly. If they
are not, operate the valve manually until they are correct.
4. Remove actuator cover.
5. Bring power to the actuator. CAUTION: Make sure power is OFF at the main
box.
6. Wire the actuator per the diagram attached to the inside of the cover. Special
actuators (those with positioner boards, etc.) will have diagrams enclosed inside
the cover.
7. Securely tighten bolts used to mount the actuator to a mounting bracket or
directly to the valve mounting pad if it is ISO5211 compliant.
8. Cycle the unit several times and check the open and closed positions of the
valve. Cams are pre-adjusted at the factory; due to the variety of valve designs
and types however, slight adjustments might be required.
9. Replace cover and tighten screws.
To Set The Open Position
1. Cycle the valve to the open position by applying power to terminals. The top cam
and switch control this position. In the open position, the set screw in the top cam
will be accessible.
2. If the valve is not open completely:
a. Slightly loosen the set screw on the top cam.
b. Rotate the cam clockwise (CW) by hand until the switch makes contact.
Contact is made when a slight click can be heard. By making incremental
CW movements of the top cam, the valve can be positioned precisely in the
desired position.
c. When the top cam is set, tighten the set screw securely.
3. If the valve opens too far:
a. Apply power to terminals. This will begin to rotate valve CW. When valve is
fully open and in the exact position desired, remove power from actuator.
b. Loosen the set screw in the top cam.
c. Rotate the top cam counterclockwise (CCW) until the switch arm drops off
the round portion of the cam onto the flat section. A slight click can be heard
as the switch changes state.
d. Continue applying power to terminals until valve is in the desired position.
To Set The Closed Position
1. Apply power to terminals to move the valve toward the closed position. The
bottom cam and switch control the closed position. In the closed position, the set
screw in the bottom cam will be accessible.
2. If the valve is not closed completely:
a. Slightly loosen the set screw on the bottom cam.
b. Rotate the cam counterclockwise (CCW) by hand until the switch makes
contact. Contact is made when a slight click can be heard. By making
incremental CCW movements of the bottom cam, the valve can be positioned
precisely in the desired position.
c. When the top cam is set, tighten the set screw securely.
3. If the valve closes too far:
a. Apply power to terminals. This will begin to rotate valve CCW. When valve is
fully closed and in the exact position desired, remove power from actuator.
b. Loosen the set screw in the top cam.
c. Rotate the top cam clockwise (CW) until the switch arm drops off the round
portion of the cam onto the flat section. A slight click can be heard as the
switch is no longer making contact with the round part of the cam.
d. Continue applying power to terminals until valve is in the desired position.
