Introduction

Advantages

For more than 40 years, Bettis
Corporation has been recognized
worldwide for providing industry
with high performance pneumatic
and hydraulic valve actuators. The
addition of the Bettis line of TorqPlus
electric actuators carries on the
tradition of product quality, innova­tion and service reliability.

Bettis TorqPlus actuators are specifi-

cally designed for quarter-turn
operating applications — ball, butterfly and plug valves;
dampers; vents and similar uses. TorqPlus actuators are
available in a wide range of output torques and operat­ing speeds to fit your specific requirements.

The Bettis Engineered Solution

Most electric actuators in use today are designed to
meet a range of torque and speed requirements for use
in industrial applications. Controls and optional acces­sories are often available, added at the factory while
being assembled. Heretofore, not much attention has
been given to field upgrades, inventory modifications or
parts replacement during servicing.

The Bettis TorqPlus actuators, instead, provide its users
with a unique modular approach. The actuators are
manufactured with pre-tapped holes in the base plate
to accommodate a myriad of control and accessory
components, available in more than 200 easy-to-install
kits to fit virtually every requirement imaginable. Kits
are available, depending on the actuator model, to add:

■ Heaters and thermostats

■ Potentiometers

■ Servo controls

■ Motor brakes

■ Positioners and transmitters

■ Control stations

■ Multi-turn operation

■ PLC interface

All of the components can be added inside the CSA type
4/4x weatherproof housing or the CSA type 4/4x, 7 and
9 weatherproof/explosion proof housings.

The Bettis TorqPlus, and the modular concept, offers its
users significant advantages:

■ Compact Design – The actuators provide maxi-

mum torque output relative to its small design
housing.

■ Custom Control Standards – By offering an

almost endless number of control and accessory
combinations, Bettis electric actuators can effec­tively be designed to virtually any end use.

■ Modular Construction – The modular design

allows the actuators to be easily field modified
and serviced. Accessory kits can be stored for
future use without consuming a large amount of
storage space.

■ High Strength Gearing – We precision-machine

our gears from hardened alloy steel, and run in
needle bearings. The result is efficiency, smooth
energy transfer, quiet operation and, best of all,
long service life.

■ Low Maintenance – Permanent lubrication

reduces the need for scheduled maintenance. The
actuators are supplied with low temperature
lubricant, allowing the units to perform in tem­peratures to -40°F (-40°C). All operational parts
are fully enclosed in the housing eliminating all
contact with the environment.

■ Guaranteed Minimum Torques – As with other

Bettis actuators, we guarantee that our published
output torque values are minimum values. If any
Bettis TorqPlus actuator fails to meet its specified
torque output under normal use, we will replace it.

■ Duty Cycle – All Bettis actuators are rated for a

duty cycle of at least 30% (one motor-on period
followed by two motor-off periods). Higher duty
cycles (up to 100%), which can allow for up to
1200 starts per hour, at normal ambient tempera­tures are available.

The following information may be used as a guide to
compose specifications for Bettis TorqPlus Electric
Actuators. Bettis supplies Electric Actuators that meet
or exceed all of the specifications stated below except
the Model EM-100 (which is not equipped with a manual
override feature or dual conduit entrances).

flats and shall by-pass the power gear drive and motor
for manual operation.

Actuators of 2,000 lb-in (226 Nm) or greater output
torque shall be supplied with a handwheel which will
not rotate during motor operation, but must be opera­tional at all times without danger of injury to operator.
The handwheel shall not require more than 50 lbs. of
rim force to operate under the most adverse conditions
and be capable of assisting or opposing the motor
without any form of declutching.

9. Enclosure

The actuator enclosure shall be a high-strength sand
casting and must be certified by CSA*, or equal third
party tester, as acceptable for use in the following
locations:

9.1 Non-hazardous indoor or outdoor location to pro­tect against wind-blown dust and rain, splashing
water and hose-directed water (i.e. CSA Enclosure
4 – Weatherproof, conforms to IP-65).

These very rugged and versatile electric actuators take
full benefit of precision-machining which allows every
model to provide maximum torque output relative to its
compact design configuration and contains a minimum
of parts to reduce vibration, lessen noise and resist
harsh service. Utilizing a combination of spur, worm and
planetary power gearing reduction systems, the Bettis
TorqPlus actuators incorporate the most efficient, pow­erful and appropriate drive design for service excellence.

1. Motors. Available in Single Phase, 3 Phase and DC
voltages, all motors are custom built for high-torque,
low current draw and the highest duty cycle ratings
offered. Single phase motors are capacitor run type and
three phase are squirrel cage induction type both having
integral self resetting thermal cut-outs.

2. Brakes. Offered for all AC and DC motors, they are
capable of a holding force equal to the output torque
ratings of each actuator model.

3. Heater and Thermostat. Securely mounted and
appropriately sized to insure ample protection even in
the worst environments (not visible in photo).

4. Terminal Strips. Standard in all models and allow

easy plus efficient actuator installation.

5. Capacitors. Used on all single phase AC units, each
capacitor is peak voltage rated and of improved design
for maximum service life.

6. Potentiometers. Precision mechanically linked to
actuator output drive for continuous position signaling.

7. Position Indicator. Mechanically driven and easily
viewed at top of actuator to insure or confirm actual
actuator and driven device position at all times (not
available on compact Model EM-100).

8. Dual Conduit Connections. Standard on all models,
except EM-100, allows full electrical code access of all
wiring through two NPT connections.

9. Torque Limit Switches. Standard for the high­torque 800-Series of Bettis TorqPlus actuators. These
mechanical switches eliminate potential driven device
damage due to over torque conditions in either direc­tion of operation.

10.Manual Override. Standard in all models except the
EM-100, manual override capability is offered in two
forms; Declutchable and Direct Acting.

(EM-800 Series)

Model EM-300 and the complete 500-Series

offer a Declutchable design which disengages the power
gear drive from the output shaft. Manual operation is
accomplished by rotating the exposed output shaft
drive flats with an open end wrench after the position
indicator knob is pulled up. Return to full automatic
operation is as easy as removing the wrench and lower­ing the position indicator knob to allow the mechanism
to re-engage upon application of power. Should power
be applied during manual operation, the declutchable
design will not allow the output shaft to rotate.

The 800-Series offers a Direct Acting handwheel design
which allows completely safe operation at any time and
with never more than 50 pounds of rim pull force.
Operating independent of the motor but directly into
the power gear drive, the handwheel does not rotate
during automatic operation of the actuator, requires no
engagement action for manual operation and may be
rotated with or without power to the unit.

10

11.Enclosures. Made from high strength sand castings,

enclosures are rated for applications in both Non-haz­ardous and Hazardous locations. As an option, the Bettis
TorqPlus is also available with a CSA Certified combina­tion Hazardous and Non-hazardous enclosure for indoor
and outdoor protection in locations classified Class I and
II, Groups C, D, E, F and G as defined in the National
Electrical Code plus protects against wind-blown dust,
wind-blown rain, splashing water and hose-directed
water.

12.Output Drives are corrosion resistant. Female drives
are available in a variety of DIN/ISO 8-point sizes. Male
drives are also available on models 300 and 500. The
EM-800 series is provided with bored drive sleeve with
double keyways.

13.Powder Coat Finish. A polyester external coating
developed to serve as both a high durability impact and
chemical resistant finish. With up to 160 lb-in ASTM
D2794 impact resistance, over 1000 hours ASTM B117
salt spray rating and 1000+ hours ASTM D2247 humidi­ty resistance, this protective finish will stay in place and
do the job.

TorqPlusTMElectric Actuators

Torque 300 IN/LB – 1,600 IN/LB

MODEL EM-SR5

The Engineered Solution

Bettis TorqPlus has taken the lead in offering compact,
cost effective Spring Return Electric Actuator Packages.
Three models offer a variety of solutions when one needs
to protect a system upon loss of power. These actuators

have been designed for dampers, small

butterfly, ball and plug valves.

The Model EM-SR5 Series

is designed for use in
environments where auto-

matic closing/opening
is required upon loss of

power, with a rugged

versatility that is hard

to beat.

When power is
available, the

device operates like

a normal quarter turn,

open/close or modulating

actuator. Under powered opera­tion, the spring pack travels with
the movement of the actuator.

Under powered stopped

conditions, the actuator and

spring are held in position

via the electric mechanical

brake. Upon loss of power, the

spring is released and drives

actuator to the predesignated
failsafe position. The failsafe
positioning can be provided for

either the CCW limit or to the

CW limit.

application and continuing identification. The following
represents the typical information included on the
nameplate and the meaning.

Model: Model – Operating Speed – Enclosure Type –

PRODUCT IDENTIFICATION

A.C. – Alternating current/voltage flowing in both

directions alternately.

Amphere (Amp) – The unit of electric current, defined

in terms of the force between a pair of wires.

Auxiliary Switch – A switch used to energize or

de-energize other equipment (such as lights or pumps).
Supplied with its own cam to synchronize other equipment
at any point of travel.

Capacitor – A device having the property of storing an

electrical charge.

CSA – Canadian Standards Association
D.C. – Direct current/voltage which has a constant value rated

to zero. Steady current in one direction.

Duty Cycle – A mathematical calculation, expressed as a

percent, to indicate available motor-on (running) time with­out endangering an over heating condition which would
terminate actuator operation.

Using an actuator with a 10 seconds/90° operating speed
and rated for a 50% duty cycle as an example, safe, non­interrupting operational periods would be: One 10 second
motor-on period followed by one 10 second motor-off
period. Total calculation time is 20 seconds of which 50% is
motor-on time.

Proper application of the duty cycle rating allows ample
time for the motor to dissipate internal heat and thereby
not cause a thermal overload cutoff.

Enclosure – The housing that surrounds the actuator’s operat-

ing parts. It can either be weatherproof or explosion proof.
The enclosure generally protects the electrical equipment
from the environment and/or prevents an explosion within
the enclosure from causing an external explosion.

Hertz – Unit of frequency. Equal to one cycle per second.
NEMA – Acronym for National Electrical Manufacturers

Association.

NEMA 4 – Rating designation for weatherproof enclosures.

Pliable gaskets are used on all metal-mating parts to prevent
moisture from entering.

NEMA 7 – Rating designation for enclosures suitable for con-

taining internal explosion without rupturing the enclosure
and without igniting surrounding gases in the atmosphere.
Metal-to-metal sealing is required in these rated products.

Ohm – International unit of electrical resistance. The resistance

in ohms between two points is defined by the DC voltage
divided by the DC current flowing between the points.

Reversing Starter – Its purpose is to connect, disconnect

and reverse electricity to the motor. Also called reversing
contractor, reversing controller or integral starter.

Torque Limit Switches –

Switches designed to monitor physical
variables or operating states and to open circuits in the
event of pre-set limits being exceeded.

Vol t – Unit of potential difference or electrical potential. It

represents the amount of work done per unit charge in
moving a charge from one place to another.

TorqPlusTMElectric Actuators

Multi-Turn Operation

Option allows for multiple revolution on non-rising
stem devices.

Electrical Mechanical Motor Brake

Available for all actuator models. Brakes are employed
to eliminate motor run-on and to insure that the
actuator and driven device maintain their position.
Recommended applications include; all resilient seated
valves, valves with high flow rates, all modulating
services and any time in which increased position
control is needed.

Three Position Control

Typically used for multiported valves, operation can be
set for 0°-45°-90° or 0°-90°-180° with a stop at mid
position from one extreme or both.

Potentiometers

Mechanically linked to the actuators output to provide
a resistance signal proportional to the actuator’s and
driven device’s position. Used to give continuous feed­back to control panels, modulating position control and
other closed loop devices.

CONTROLS AND OPTIONS

Torque/Current Trip Module

(for DC Motors)

■ Protects the valve and actuator from excessive

torque conditions by comparing the motor cur­rent with a factory adjustable trip value.

■ Provides dynamic braking, in order to improve

positioning accuracy at both mid and end of trav­el stop points. (Caution: A mechanical brake
should also be used in conjunction with the
dynamic brake feature, for applications that
require the valve to be held in place after stop­ping.)

Control Latching Relay

■

Allows the actuator to run full travel upon receiving
a non-maintained control signal, ranging from
0-240VAC or 0-110VDC.

Control Relay

■ Provides a means of opening and closing a valve

with a variety of standard AC or DC maintained
control signals, such as 120 VAC, 24 VAC, 12 or
24 VDC.

■ Can be used for a fail close (or open) application

upon loss of the control signal. An internal coil
(designed to be continuously energized) main­tains the open signal to the actuator. When the
signal is removed, the coil de-energizes, causing
the actuator to close.

Additional Control Options

■ Up to 6 SPDT aux. limit switches

■ Electronic Transmitters (4-20mA output from a

DC transmitter or 4-20mA, 0-10V output from
an AC transmitter)

■ Dual 1k ohm potentiometers

■ Two speed operation (pulse timer package)

■ Unidirectional controls (up to 30 rotations)

■ Control stations including buttons, lights, selector

switches

■ 3-phase motor controls

■ Three position operation (such as 0-45-90 or

0-90-180 degrees)

■ Torque seating for multi-turn and quarter turn

■ Torque switch trip indication

CONTROL STATIONS

Control Stations are available in a variety of standard
weatherproof wall-mounted and close-coupled configu­rations using the following 5-digit code system:

Typical Options

Timer packages, control relays, special labeling, LED
lights, pad lockable switches, space heaters and
Canadian Underwriter Laboratory labels.

Additional options for 3-phase wall-mounted CS’s
include starters, control transformers, and overload
relays.

sitions on a second

The Remote Signal Generator (RSG) (supplied in a wall­mounted enclosure) produces a 4-20mA output signal,
by manually rotating the dial. From a remote location,
this output signal can then be used to position or throttle
an actuator equipped with an integral modulating
board.

The RSG can also be used in conjunction with a closed­coupled “CS” control station.

are proportional motor controllers for actuator modu­lating applications. The C1397 is for actuators with AC
powered split phase motors. The C1415 is for use with
12 or 24VDC powered actuators. These controls are
designed to proportionally position an actuator and the
driven device by comparison of a varying external input
command and a mechanically linked potentiometer.
Input commands can be 0-10V, 1-5V, or 4-20mA. The
servo also allows for three responses to command signal
loss (1-5V and 4-20mA only); fail in place, fail to full
clockwise (CW) position, or fail to full counterclockwise
(CCW) position.
