It is important to consider a few factors when choosing the right actuator for your application. In addition to usage factors, sizing, supply pressure requirements, safety and reliability, and cost considerations, there are many other factors to consider. Let’s have look.
FREMONT, CA: Machines are an essential aspect of manufacturing industries. Every machine has several components attached to it for performing different functions. Actuators are also vital to machines as they are responsible for the movement and control of mechanisms like valve opening in machines. It converts electrical, hydraulic, and air energy into mechanical energy to support the movement. Selecting extremely effective actuators for machines to optimize mechanical work becomes essential. The selection of actuators requires immense knowledge of actuation mechanisms and their compatibility with the other operative circumstances. A proper and effective actuator ensures the safety of machines and the security of machine operators.
Automating valve operations is becoming a trend in many industries. Innovative technologically evolved instruments and cutting-edge computational devices have empowered industries to automate valve operations to optimize the performance of valves in various piping systems. The actuators are highly accurate and are found in various sizes to fit the industrial valves. It controls the fluid flow by controlling the closure mechanism of valves.

Few tips to know while selecting actuators that can help companies save machines, increase efficiency, and maintain safety standards.
Identify the availability of appropriate power sources: Different actuators are available for various types of machinery processes. They are distinguished based on their power source. For instance, pneumatic and hydraulic actuators need fluid power to operate. Therefore, while operating these actuators, engineers must check the quality of the air supply for generating power for the actuator. A clean air supply, efficient air compressor, good air supply pipes, and accurate composition of air distribution are essential throughout the operational process.
Power source safety check is equally important for actuators to avoid hindrance while operating.
Determination of desired fluid control function: When selecting the actuators, engineers must understand their functionalities. Valves provide various options like on and off function and throttling. Automated valves behave according to the pressure conditions in the pipeline. Engineers must focus on the actuator signal controls, which detect the quality of the flow of control.
Due to frequent changes in pipeline pressure, a heavy-duty actuator is selected for throttling valves for its complex functions. A quick response from the actuator is required to support such dynamic changes in pipeline pressure. Understanding fluid control is vital when choosing actuators as it controls the quality and pressure of fluids. Compatibility with the operation instruments is essential for actuators because it monitors the fluid properties at various stages of a mechanical process.
Evaluate the torque and thrust requirements of the actuators: The valve size and the fluid characteristics decide on the torque requirement of the actuators because large valves need greater force to work. Also, viscous fluid will require more force for the closure mechanism to deal with the viscous resistance of the fluid. Actuators with high torque are expensive due to their power consumption.
Process engineers select actuators by determining the factors associated with the valve and operational fluid nature.
