DESCRIPTION
The Series ABV combines a durable full port, forged brass
ball valve with a Nema 4 electric actuator to provide a
compact, low cost, automated package. The brass ball
valve utilizes PTFE seats and body seals for broad chemical compatibility and bubble-tight shutoff. Double o-ring
stem seals provide leak free operation without the need for
adjustment. Chrome plated brass ball reduces friction
allowing for a lower torque actuator. Full port design offers
high Cv’s with minimal pressure drop. ISO mounting pad
allows direct mounting of electric actuator. Select from
115 VAC, two-position actuator for open/close control, or
provide a 4-20 mA control signal for precise modulating.
Actuator features standard manual overide, in case of
power loss.
INSTALLATION
1. Operate valve manually and place in the open position.
(NOTE: ALL ELECTRIC ACTUATORS ARE SHIPPED 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. Mount actuator to valve. Do not tighten nuts and bolts at
this time.
5. Remove actuator cover.
6. Bring power to the actuator. CAUTION: Make sure
power is OFF at the main box.

7. 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.
8. Securely tighten bolts used to mount the actuator to a
mounting bracket or directly to the valve mounting pad if it
isISO5211 compliant.
9. 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. (SEE II and III.)
10. Replace cover and tighten screws.
TO SET THE OPEN POSITION
1. Cycle the valve to the open position by applying power
to terminals #1 and #2. 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 8-32 x 1/4” 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 #1 and #3. This will begin to
rotate valve CW. When valve is full 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 #1 and #3 until
valve is in the desired position.
TO SET THE CLOSED POSITION
1. Apply power to terminals #1 and #3 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 8-32 x 1/4” set screw on the bottom
cam.
B. Rotate the cam counter-clockwise (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 postioned
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 #1 and #2. 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 #1 and #3 until
valve is in the desired position.
MAINTENANCE
Once the actuator has been properly installed, it requires
no maintenance. The gear train has been permanently
lubricated and in most cases will never be disturbed. In the
event it becomes necessary to open the gear box for any
reason, however, Shell Darina #2 grease is recommended
for re-lubricating.
DUTY CYCLE
Most standard electric actuators are rated for 25% duty
cycle at 100% ambient temperature at the rated torque.

THERMAL OVERLOAD
All actuators are equipped with thermal overload protection
to guard the motor against damage due to overheating.
MECHANICAL OVERLOAD
All actuators are deigned to withstand stall conditions. It is
not recommended to subject the unit to repeated stall
conditions.

potentiometer; valve positioner board
NEMA 7 ELECTRIC ACTUATORS
In general, operation and maintenance of a NEMA 7 electric actuator is no different that of a NEMA 4 actuator.
However, some precautions must be followed:
1. DO NOT under any circumstances remove the cover of
the actuator while in a hazardous location. Removal of the
cover while in a hazardous location could cause ignition of
hazardous atmospheres.
2. DO NOT under any circumstances use a NEMA 7 electric
actuator in a hazardous location that does not meet the
specifications for which the actuator was designed.
3. Always mount and cycle test the actuator on the valve in
a non-hazardous location.
4. When removing the cover, care must be taken not to
scratch, scar of deform the flame path of the cover and
base of the actuator, since this will negate the NEMA rating
of the enclosure.
5. When replacing the cover on actuators rated for both
NEMA 4 & 7, take care that the gasket is in place to assure
proper clearance after the cover is secured. After the cover
screws are tightened, the clearance between the cover and
the base should be checked. A .002” thick by 1/2” wide
feeler gauge is used for this; it must not enter between the
two mating faces more than .125"
6. All electrical connections must be in accordance with the
specifications for which the unit is being used.
7. Should the unit ever require maintenance, remove from
the hazardous location before attempting to work on the
unit. If the actuator is in a critical application, it is advisable
to have a standby unit in stock.
