Bettis products are used in almost every
energyrelated industry, including oil and
gas oduction - both onshore and offshore
- oil and gas trans-mission, petrochemical
and petroleum refining. Other markets
include chemical, power industry including
nuclear, pulp and paper, food and
beverage, pharmaceutical, textile and
water system.

Bettis' CBA-Series pneumatic actuators are compact, lightweight
and ideally suited for automating ball, butterfly
and nonlubricated plug valves, or any quarter
turn (90 degree) rotating mechanism. These
efficient, low maintenance actuators,
with optional controls, provide a reliable
method of operating and confirming valve
position for a fully automated process.
The CBA-Series, available in double-acting and
springreturn models, are independently certified
to BS 5490: 1977 - IP66 and IP67M for water
ingress protection. Doubleacting CBASeries
actuators, requiring pressure to rotate in
either direction, are available with
guaranteed minimum torque outputs
to 12,245 lb-in (1,384 Nm). |
 |
The CBASeries springreturn models require
pressure in only one direction of travel
and are suitable for fail clockwise or
counterclockwise applications without
modification. These models produce gua
-ranteed spring ending torques to 4,971
lb-in (562 Nm). Standard construction
CBA-Series actuators are designed for
operating temperatures of -20°F to +200°
F (-30°C to +95°C). High temperature
trim allows continuous operation from 0°
F to +350°F (-18°to +177°).
Additionally, low temperature trim allows
operation from -40°F to +180°F (-40°C
to +82°). Consult factory when tempera-ture requirements exceed these limits.
Operating pressures for the CBA-Series
range from 40 up to 150 Psig (3 to 10 Barg).
Typical Applications:
Automation of ball, butterfly and plug
valves Automation of louvers and dampers
Automation of any quarter-turn mechanism
Key Features:
Outer LipType Torque Shaft Seals restrict
external contaminants, providing a high
level of corrosion and water resistance ORing
Sealed Cylinders essentially eliminate
the possibility of any cylinder leakage
throughout the full range of operating
and climatic conditions Standard Accessory
Mounting Pad is identical on all CBA and
CBA-300 Series models allowing the panel
mounting of controls
Piston Heel and Yoke
Pin Bearings man-ufactured from PTFE/bronze
help ensure smooth and consistent torque output
and increase total cycle life
Totally Enclosed Body
provides complete protection of all internal moving
parts and minimizes the chance of injury to
operating
personnel The ScotchYoke Mechanism transforms
linear movement of the piston into
a 90 degree rotating movement,
providing optimum start or end torque
Center Bar, made of high strength alloy
steel, guides the piston throughout
its full stroke, preventing metal to
metal contact with the cylinder bore
Bidirectional Travel Stops are an
integral part of the actuator all-owing 80° to 100° total travel
adjustment. Extended travel stops
are optional Critical Bearing Surfaces are
permanently lubricated with a baked
on dry film lubricant containing
unique corrosion inhibitors
XylanTM Cylinder Coating, the
standard internal coating on all CB-ASeries actuators. This
fluoropolymer coating is highly resistant to abras-ion,
thermal shock and provides excel-lent lubricity and low
friction proper-ties. Corrosive properties of salts and
other chemicals normally found in the
atmosphere or instrument air supply
system will not adversely affect its
performance. XylanTM bonds to the
chemically prepared surface of the
steel cylinder so effectively tha-t, unlike other coatings, cracking
and flaking are virtually eliminated
Dual Valve Mounting Interface allows
the flexibility to change the spring
fail mode, without disassembly of the
actuator, by simply inverting the act-uator. They may be installed in any po-sition; parallel or
at right angles to the flow line, in the vertical or the horizontal planeWellGuard? PWG Valve
Actuators
The WellGuard? piston range of pneuma-tic Control Fluid Powered linear actua-tors is designed to be used in conjunc-tion with Bettis valve bonnets to prov-ide open and close
control for major b-rands of API 6A through conduit reverse acting gate valves fitted to oil and
gas
wellheads and production flow lines.
These actuators can be used with API
6D and ANSI B16.34 valves where the
bonnets are built to Bettis design.
Key Features
Lightweight
Actuator Upper Shaft acts as visual
position indicator
Easy maintenance and disassembly, no
special tools required
Construction uses no large mounting
threads, eliminates galling and corrosion
Designed for interchangeability with Bettis

The company headquarters in Waller, Texas (near
Houston) houses more than 145,000 square feet
of covered manufacturing, research, engineering
and office facilities. Bettis also has an 88,000 sq-uare foot manufacturing facility in Canada
, avalve automation facility in France, and
a direct sales office in the United Kingdom.
Since Bettis Corporation's inception, it has
continuously expanded both its physical capacit-y and its product lines. Its growth has come, in
part, from the acquisition of some of the worl-d's most reputable actuator manufacturers wit-h a myriad of offerings and specialties. As a r-esult of these acquisitions, Bettis now operate-s plants worldwide coupled with a global sales
and distribution network unmatched in the indus-try.
