The Series 3BV3 incorporates a full port design for maximum flow rates with minimal
pressure drop. Features include a blowout proof stem for added safety and reinforced
RTFE seats and seals for longer life and leak free operation. The four seat design
allows for high cyclic capabilities and tight shut off in any position. Perfect for mixing
or diverting services in the food and chemical processing industries.
The 3BV3 is an economical automated valve package with either an electric or
pneumatic actuator. Electrically actuated models are weatherproof, NEMA 4, powered
by standard 115 VAC supply, and are available in either two-position or proportional
control. Two-position actuators use the 115 VAC input to drive each of the valve ports
open or closed, while the modulating actuator accepts a 4 to 20 mA input for infinite
valve positioning. Actuator features include thermal overload protection to withstand
stall conditions, visual position indication and a permanently lubricated gear train.
The pneumatic double acting actuator uses an air supply to drive each of the actuator
ports. The actuator has two supply ports with one driving the valve stem clockwise,
the other for counterclockwise rotation. Spring return pneumatic actuators use the
air supply to drive the valve stem one direction, and internally loaded springs return
the valve to its original position. Also available is the SV3 solenoid valve to electrically
switch the supply pressure between the air supply ports. Actuators are constructed
of anodized aluminum and are epoxy coated for years of corrosion free service.

ELECTRIC ACTUATOR
I. BASIC 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 is ISO5211 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.
II. 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.
III. 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 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 #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.
IV. 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, Darina® #2 grease is recommended for re-lubricating.
V. DUTY CYCLE
Most standard electric actuators are rated for 25% duty cycle at 100% ambient
temperature at the rated torque.
VI. THERMAL OVERLOAD
All actuators are equipped with thermal overload protection to guard the motor
against damage due to overheating.
VII. MECHANICAL OVERLOAD
All actuators are deigned to withstand stall conditions. It is not recommended to
subject the unit to repeated stall conditions.
VIII. SPARE PARTS
When ordering parts, please specify:
A. Model # B. Serial # C. Part Description
Recommended spare parts include:
A. Standard actuator: set of cams and switches.
B. Actuators w/positioner: set of cams and switches; 1K potentiometer; valve
positioner board.
IX. 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.
Page 3
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.

PNEUMATIC ACTUATOR
PNEUMATIC ACTUATOR
Note: For optimal operation, 3BV3 actuators should be run with a supply of
clean, lubricated air.
SPRING RETURN ACTUATORS
Air to PORT 2 (the right hand port) causes the actuator to turn CCW. Loss of air
to PORT 2 causes air to exhaust and the actuator turns CW. This is the FAIL
CLOSE operation.
DOUBLE ACTING ACTUATORS
Air to PORT 2 (the right hand port) causes the actuator to turn CCW. Air to PORT
1 (the left hand port) causes the actuator to turn CW.
DISASSEMBLING STANDARD ACTUATORS
IMPORTANT: Before beginning disassembly, ensure that the air supply to the
actuator has been disconnected, all accessories have been removed and that the
actuator has been dismounted from the valve.
1. Loosen the end cap fasteners (22) with a wrench (size varies depending on
actuator model). On the spring return actuator, alternate 3 to 5 turns on each
fastener until the springs are completely decompressed. Use caution in
removing the cap since the springs are under load until the fasteners are fully
extended.
2. Remove the pinion snap ring (10) with a lock ring tool. The indicator (7) may
now be removed.
3. Turn the pinion shaft (2) CCW until the pistons are at the full end of travel.
Disengage the pistons (11) from the pinion. (NOTE: Low pressure air--3 to 5
P.S.I. MAXIMUM--might be required to force the pistons completely from the
body.) Note the position of the pistons before removing them from the
actuator body. The part numbers of the pistons are located on the side and
should be right-side up on an actuator with a standard orientation.
4. Remove the pinion through the bottom of the actuator. The actuator is now
completely disassembled. All replacement parts may now be put in. W.E.
Anderson recommends that all wear parts (3, 4, 5, 6, 12, 13, 14) be replaced
before reassembly.
REASSEMBLING STANDARD ACTUATORS
IMPORTANT: Be sure that the actuator surfaces are free of grit and
scratches before reassembling.
1. Apply a light film of grease to all o-rings and the pinion before replacing.
2. Put the pinion (2) back through the actuator with the flats of the pinion shaft
running parallel with the body.
3. When reassembling the actuator, make sure that the piston racks are square
to the actuator body and returned to their original orientation. (NOTE: The
normal operation of all BV pneumatic actuators is FAIL CLOSED. To change
the orientation to FAIL OPEN, rotate the racks 180º to create a reverse
operation.)
4. When replacing springs in a spring return actuator, ensure that the springs
are replaced in their identical position in the end cap from which they were
removed. (Note: In some circumstances, you might want to change the
standard 80 pound spring set to fit your application and available air pressure.
Changing the spring sets on BV pneumatic actuators requires no special
tools. Please refer to the spring combination torque chart in our catalog for
the inner and outer spring combinations that will allow you to operate with the
spring set that you desire.)
4. Seal the end caps with a petroleum lubricant and bolt to actuator body.
5. Check the seal of the actuator by covering seal areas (pinion, end caps) with
soapy water and using low pressure air to the actuator to ensure that no
bubbles are produced.
