THINGS THAT NEED TO BE CONSIDERED WHILE CHOOSING AN ACTUATOR With the arrival of new technologies, the process industry has been able to achieve more efficiency and productivity. One of the tools that help in achieving the best results is a valve actuator. The equipment has a simple input (the power supply) and an output (the torque) with the help of a mechanism that enables the operation of the valve. To ensure the most impressive technical and economic output, you need to know no a few considerations that are important when it comes to the selection of actuators. While the quality of the valve depends on the mechanical design, the actuator is responsible for the metallurgy and its performance in the control loop. Bettis is one of the most renowned brands that offer various types of actuators. It is your one-stop destination where you can find the widest range and pick the one that ideally fits your requirements. Bettis actuator springs are a crucial part of the actuator that is considered to be the best in the industry for its quality as well as performance. The function of automating a valve is based on one or all of the considerations mentioned below - Control and process system performance Excessive valve torque Safety and reliable operation Inaccessible or remote valve location Cost Emergency response and whether it is fail-safe Compatibility - The one thing that needs to be considered in the selection of an actuator type is the most effective power sources. The points to keep in mind are - Torque at the valve stem Power source availability Speed of operation Size of valve Control accessories
Plant environment Frequency of operation Failure mode System maintenance System component costs Bettis pneumatic actuators with the utilization of an air pressure supply of 40 to 120 psi (3 to 8 bar) are the ideal selection. Higher pressure is generally difficult to guarantee outcomes, and low pressures require a large diameter piston or diaphragm for the generation of operating torque. Spring return - Spring return for valve operation is one of the accessories that is widely specified in the process industry. It is helpful when there is a power or signal failure as it drives the valve of the actuator to a predetermined position. The Bettis pneumatic actuators primarily use spring return as a practical and inexpensive option. The Bettis actuator springs enhance the functioning of the tool. Electric actuators generally do not have a spring return version. The bottom line - Now that you have gone through the post, you will know what activators are all about. Yet, to conclude, actuators are widely used in process industries to make their mechanism easier and more progressive as well as fruitful. Bettis is a common name in the industry, making top-notch quality actuators. Bettis actuator spring is one of the most functional parts of the instrument that helps in the better operation of the valves. The above post includes all the things that you need to know about while selecting the one that is ideal for your purpose.
