Complete Valve Automation and Control Solutions
Actuators are an essential element in any automated assembly. Each one must be carefully chosen to meet the requirements of the valve on which it is mounted and the intended application. Possibilities include pneumatic (whether rack and pinion or scotch-yoke), electric, and hydraulic actuators in a wide range of torques and sizes to meet your needs at the most economical price. In addition, application, safety factors, actuation time, temperature, and emergency response must be considered to optimize the assembly to your needs. Vinson stocks a large variety of actuator lines and models in order to handle almost any actuation requirement that you may have both quickly and efficiently.
Manufacturers of the Broadest Variety of Valve Actuator Types, Bettis
For more than 40 years,
been recognized as a leader in the manufacture of actuator products.
Bettis manufactures a complete line of products, including quarter-turn
scotch-yoke, rack and pinion, and electric
actuators for your actuation
requirements. These actuators, available in both spring-return and
double-acting configurations, can be powered by either compressed gas,
hydraulic, or electric sources to provide the widest range of torques and
thrust available in the industry.
Compact rack and pinion pneumatic actuators operate reliably and efficiently in many quarter-turn applications including ball, butterfly, and plug valves. Available in a wide range of torques, and in either double-acting or spring-return models, you can count on Bettis products to operate reliably through extreme temperatures, corrosive environments, and high cycles.
Scotch-yoke pneumatic actuators are now available for many applications both large and small. The Bettis G series offers such features as guaranteed output torques, water ingress protection, corrosion resistance, NAMUR standardization, close coupling, and overrides. These actuators can operate up to 6 million inch-pounds for double acting models and 3 million inch-pounds in spring-return models. Operating pressures up to 200 psig and temperatures as high as 200 degrees Fahrenheit are also possible.
Bettis hydraulic actuators come in scotch-yoke, linear, and helical-spline models. Manufactured in both double-acting or fail-safe spring-return designs, they can be used both offshore and in subsea applications as well as on land. Bettis hydraulics are available in torques up to 6 million inch-pounds in double-acting models and 3 million inch-pounds in spring return.
Gas hydraulic actuators are found on natural
gas pipelines throughout the world. Operating in a temperature range
from -50 to
Bettis electric actuators are compact and can
provide ideal performance in on/off and modulating environments. Suitable for use on all sizes of valves, these actuators come in both
hazardous and non-hazardous housings including CSA-certified
enclosures. Standard models are available with a wide range of options
for control functions.
For applications involving
extreme temperature ranges or corrosive chemicals,
actuators may be an excellent choice for your continuous process or
batch conditions. Available from 40 to 120 psig air supply, these
actuators feature dual opposed and balanced piston design for optimum
performance and long life. Integrated control options include manual
override, a three-position positioning system, limit switches, solenoid
valves, and breather blocks.
The Smart Solution to Integrated Control, FieldQ
FieldQ actuators greatly reduce assembly and installation costs by allowing the user or valve automation shop to integrate the actuator, solenoid valve, switch box, and accessories into one product. Covered by various patents on the way controls are integrated into the product, the design of the pneumatic control module, and the contactless position sensing, the FieldQ will revolutionize the piecemeal approach to automated valve assembly. Upgrades are also much easier with plug in modules that eliminate the need to hang various accessories all over the assembly.
Other features available with FieldQ include push-button initialization of position indicators and intelligent diagnostics to notify the operator of actuator/valve condition. In addition, digital communications are available for several standard bus protocols allowing you to harness the power of PlantWeb® for yet another facet of your operation. With FieldQ, estimating is a thing of the past, now you can know the status of your valve assembly and take control of your process.
Designed for rotary
valves, the FieldQ utilizes only those features necessary for the
application and is an economical alternative for almost any
Rexa Actuators are commonly used for all types of damper controls, burner tilts and other applications requiring high speed and precise control. They are available in fail-last and fail-safe models without sacrificing speed of response.
