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

The CBA-Series spring-return models require pressure in only one direction of travel and are suitable for fail clockwise or counterclockwise applications without modification. These models produce guaranteed 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°C to +177°C). Additionally, low temperature trim allows operation from -40°F to +180°F (-40°C to +82°C). Consult factory when temperature 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 Lip-Type Torque Shaft Seals restrict external contaminants, providing a high level of corrosion and water resistance

O-Ring 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 manufactured 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 Scotch-Yoke 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

Bi-directional Travel Stops are an integral part of the actuator allowing 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 CBA-Series actuators. This fluoropolymer coating is highly resistant to abrasion, thermal shock and provides excellent lubricity and low friction properties. 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 that, 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 actuator. They may be installed in any position; parallel or at right angles to the flow line, in the vertical or the horizontal plane

WellGuard? PWG Valve Actuators

The WellGuard? piston range of pneumatic Control Fluid Powered linear actuators is designed to be used in conjunction with Bettis valve bonnets to provide open and close control for major brands 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.

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 square foot manufacturing facility in Canada, a valve 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 capacity and its product lines. Its growth has come, in part, from the acquisition of some of the world's most reputable actuator manufacturers with a myriad of offerings and specialties. As a result of these acquisitions, Bettis now operates plants worldwide coupled with a global sales and distribution network unmatched in the industry.
