Strong, Efficient and Cost Effective

CBA-300 SERIES PNEUMATIC

DESIGN AND CONSTRUCTION

Introduction

For more than 45 years, Bettis®valve actuators have

demonstrated the latest technology. The CBA 300-

Series pneumatic actuators combine the strengths of

our new generation G-Series scotch-yoke actuators,

while incorporating several new design economies for

efficient and cost effective operation.

The advanced 300-Series have enhanced water ingress

and corrosion protection. These compact actuators are

lightweight and ideally suited for automating virtually

any quarter-turn (90-degree) rotating mechanism

including ball, butterfly and plug valves. With a variety

of options, the 300-Series can meet your most demand-

ing valve automation needs.

Operating Ranges

Double-acting 300-Series actuators are available with

guaranteed minimum torque outputs ranging from

7,388 lb-in to 20,337 lb-in (835 to 2,333 Nm). 300-Series

spring-return models require pressure in only one

direction of travel and are available for fail clockwise or

counterclockwise applications. These models produce

spring ending torques ranging from 2,532 lb-in through

10,457 lb-in (286 to 1,182 Nm).

Standard construction 300-Series actuators are

designed for operation temperatures ranging from -20°F

to +200°F (-29°C to +93°C). Optional high temperature

trim allows operation from 0°F to 350°F (-18°C to +177°C)

and special non-PED low temperature trim permit

operation to -40°F (-40°C).

Pneumatic operating pressures for the 300-Series

range from 40 to 150 PSIG (3 to 10 BAR).

Features and Advantages

Water Ingress Protection – The 300-Series actuators meet both IP66 and

IP67M specifications for submergence and severe high pressure water del-

uge test, offering superior water ingress and corrosion protection. The actu-

ator has no gaskets and is totally o-ring sealed.

1) NAMUR Topworks

– The 300-Series utilizes the internationally accepted

NAMUR mounting configuration that allows standardization of accessory

hardware and the direct or close coupling of NAMUR designed hardware

and accessories.

2) New Quad Sealed Torque Shaft – The lower torque shaft has two

independent seals – the outer seal protects the large bearing area and

the primary, inner cup seal from the environment. The upper shaft

bearing area features a bi-directional, double lip seal providing twice

the level of protection from corrosion and contaminants.

3) New O-Ring Sealed Cylinders – The o-ring sealed cylinders essentially

eliminate the possibility of any cylinder leakage throughout the full

range of operating pressures and climatic conditions.

4) Name Plate – Long lasting stainless steel plate provides lifetime trace-

ability and critical operating information.

5) Standard Accessory Mounting Pad – The new accessory mounting

pad is standard and identical on all CBA and CBA 300-Series models,

allowing for the panel mounting of controls.

6) Jackscrew Option (Shown) – A blowout-proof, economical jackscrew

manual override is available with the 300-Series. When equipped with

a jackscrew, it also acts as a stop adjustment screw. The jackscrew

feature has several advantages:

■Produces full rated torque output in the event of air supply loss.

■Available with or without handwheel, locking devices and many

other options. Consult factory.

■The manual override absorbs impact loads at maximum

recommended actuator speeds.

■Double-acting models are available with one or two jackscrews.

Bi-directional Travel Stops – Dual stops

allowing 80° to 100° total travel adjustment.

This feature provides an unmatched travel

range to assist in prolonging valve seat

integrity.

Optional Bi-directional Extended Travel

Stop (ETS) – Allows 0° to 100° extended

travel adjustment capability, and can be

used as a lockout device. Consult factory.

7) ISO/DIN Actuator/Valve Interface – The 300-Series has an ISO/DIN

F14 mounting configuration. This female interface allows close

coupling or direct mounting of the actuator to the valve topworks.

Standard stop screw

8) Efficient All Bearing Design – The 300-Series pis-

ton has three field replaceable bearings. They

include a TFE piston head bearing, PTFE/bronze

bearings on either piston end and on the yoke pin.

These bearings help to assure smooth and consis-

tent torque output, while enhancing total cycle life

capabilities.

9) Torque Shaft Bearing – The torque shaft

features field replaceable upper and lower

PTFE-coated, copper-clad metallic bearings.

10) Xylan™ Cylinder Coating – This fluoropolymer

(TFE-based) coating is highly resistant to corrosion

and thermal shock. It also provides for excellent

lubricity, adding significantly to piston seal life and

actuator efficiency. Xylan has been laboratory

(ASTM B117) tested and field proven to be extremely

resistant to contaminants typically found in instru-

ment air supply systems.

11) Springs – High-strength, high-performance alloy

carbon steel springs are protected by Tactyl 50, a

pliable self-healing coating. Bettis takes and addi-

tional step and shot peens the springs, helping to

extend the actuator’s spring cycle life.

12) Ductile Iron Housing – CBA actuator housings are

made of pressure vessel quality ductile iron which

is approved for use by ASME and the Pressure

Equipment Directive (PED 97/23/EC). All housings

have been optimized by finite element analysis and

are designed for light weight while retaining

maxi-

mum strength, ductility and corrosion resistance.

13) Center Bar and Torque Shaft – Utilizes a

proprietary surface conversion process, producing

an extremely hard surface exhibiting excellent wear

and corrosion resistance. The center bar guides the

piston throughout its full stoke, preventing metal

to metal contact with the cylinder bore.

screw configuration)

General Definitions

To clarify and standardize terminology, Bettis offers the

following definitions for terms commonly used. Please become

familiar with and use the following standard definitions when

referring to Bettis quarter-turn actuators.

Quarter-turn: A device which rotates a minimum of 90 degrees.

All Bettis quarter-turn actuators will rotate more than 90 degrees.

Position: That degree of rotation describing an actuator’s

current location. The mid position of a quarter-turn actuator is

generally at forty-five(45) degrees.

CW: Clockwise rotation.

CCW: Counterclockwise rotation.

Stroke: A continuous, ninety (90) degree rotation of a quarter-turn

actuator. Bettis spring-return actuators have two (2) different

strokes, a pressure stroke and a spring stroke. Bettis double-

acting actuators have two (2) pressure strokes. Note that rack

and pinon actuators have common torque valves for both pressure

strokes, while scotch yoke actuators have different torque values

depending on which side of the piston is doing the work.

Cycle: The collective reference to two (2) strokes, one (1) for

clockwise (CW) rotation and one (1) for counterclockwise (CCW)

rotation. Bettis actuators must rotate through two (2) stroke to

complete one (1) cycle.

Safety Factor: Represents a protective component (an adjustment

to torque requirement) sometimes added to a valve’s required

torque value. Often used when the user/specifier is not certain of

the valve’s torque requirements, or because of other application

concerns.

Sizing Bettis Actuators

The following information is generally the minimum required

for sizing Bettis quarter-turn pneumatic and hydraulic actuators

for specific valve requirements.

A) An accurate maximum torque requirement must be obtained

before actuator sizing begins. Normal maximum stem torque for

a properly applied and maintained valve is usually defined as: The

maximum starting torque required to rotate the valve element

(ball, disc,plug, etc.) from a fully closed position

(unsealing),

against the maximum normal valve rated different

pressures.

Most valve manufacturers make adjustments in the form of

torque amendments under various operating conditions.

Application operating conditions such as temperature extremes,

actual differential pressure, unusual loading, high flow rates,

operating speeds, etc. are some of the most common causes for

adjustments.

Bettis recommends that the valve manufacturer supply the

maximum required torque value(s) (including any adjustments

suggested safety factors). Additionally, the valve manufacturer

must identify at which position(s) and direction(s) of rotation

(CCW or CW) these maximum requirements occur.

B) Bettis actuators include stops which will resist the maximum

rated torque output of the actuator. The possibility exists, that

should the valve become immobilized during rotation, the actua-

tor could exceed the maximum allowable valve input torque rat-

ing. If this possibility is a concern, your application needs further

review.

Once the maximum torque requirements, its position, and

direction of rotation are identified, the appropriate Bettis actuator

can be selected from torque output charts on pages 4–7.

SIZING AND SELECTION

Actuator Selection Procedures

A) Determine the type of Bettis actuator required: double-acting

or spring-return.

B) Determine the power supply media: pneumatic or hydraulic,

and the minimum/maximum supply pressure(s) at the actuator.

C) Using this information, select the applicable torque rating

table and see the appropriate following examples.

Scotch-Yoke, Double-Acting Actuators (example

assumes CW to close)

Note: The valve’s torque requirements must be exceeded by

the actuator’s torque output at all corresponding positions and

directions of rotation.

Bettis has included Start, Minimum, and End pressure torque

outputs for your use.

A) Using your minimum operating pressure, select an operating

pressure column from the Pressure Torque Rating Section of less

than or equal pressure. Move down the column until both starting

and minimum output torques are found which exceed the valve’s

maximum and minimum torque requirements. Determine the

Bettis model number at the left, under the model number column.

B) Once a Bettis actuator model has been selected, use the per-

formance data tables to ensure your maximum supply pressure

does not exceed the maximum operating pressure (M.O.P.) for

your Bettis actuator. If the actuator selected is not rated for your

maximum supply pressure, either the maximum supply pressure

must be reduced or an actuator rated for a higher M.O.P. must

be selected.

Scotch-Yoke, Spring-Return, Fail CLOCKWISE Actuators

(example assumes CW to close)

Note: The valve’s maximum torque requirements must be

exceeded by the actuator’s torque output at all corresponding

positions and directions of rotation.

Bettis has included Start, Minimum, and End Spring Torque

outputs, as well as Start, Minimum and End Pressure Torque

Outputs for your use. The minimum torque outputs listed on the

Spring-Return torque charts are the lowest value of torque output

available at any position, during either stroke (pressure or spring).

A) Select from the Spring Torque column a Spring Ending torque

output which exceeds that of the valve’s maximum seating

requirement.

B) Proceed to the right using your minimum operating pressure

and select an operating pressure column from the Pressure

Torque Rating Section of less than or equal pressure. The Pressure

Start torque output must exceed the valve’s torque requirement

at this position (unseating). The Pressure End torque output must

exceed the valve’s torque requirement at this position (full flow)

and direction of rotation (CCW).

C) Once a Bettis actuator model has been selected, use the per-

formance data tables to ensure your maximum supply pressure

does not exceed the maximum operating pressure (M.O.P.) for

your Bettis actuator. If the actuator selected is not rated for your

maximum supply pressure, either the maximum supply pressure

must be reduced or an actuator rated for a higher M.O.P. must be

selected.

Contact your local Authorized Bettis distributor or a Bettis

manufacturing

facility if you require assistance.

SIL-PAC™– The unique SIL-PAC solution provides a complete hardware

and Bettis-supplied documentation package,embracing IEC, ISA and

OSHA standards, for use in a SIL application. The CBA-300 Series actuators

have a Failure Modes and Effects Diagnostics Analysis (FMEDA) report

performed by Exida.com™ for SIL suitability. They can be combined with

other components such as solenoid valves, switches and regulators. When

Fisher’s TÜV-certified FIELDVUE®DVC controller is added, SIL-PAC is capable

of partial stroke testing PLUS providing continuous monitoring of supply

pressure, valve position and pressure values to the actuator to verify its

proper working condition. The SIL-PAC package can then be mounted on

the appropriate quarter-turn valve for SIL1, 2 or 3 applications.

Bettis Automated Packages

Bettis offers complete packages as a solution for final valve control. Bettis

has the capability to combine the CBA-300 actuator, necessary controls and

selected valve into a single system – perfect for large international projects.

With this capability, Bettis can integrate its products with the complete

offering of control options, including world-class PlantWeb®digital plant

architecture and the entire range of Emerson automation solutions.

BettiSystemsTM – Bettis has pre-engineered and documented a series

of commonly required control systems. These approved systems utilize

standard components, reduce lead times, and simplify purchasing, installa-

tion and start-up. Please consult the factory for additional information.
