Actuators are now available in several designs with the ability to manage heavy-duty applications. Their functioning is not restricted to their design. With innovations in this field, heavy duty actuators are being designed in a compact fashion with higher efficiencies and performance capabilities.
Power Usage of Heavy-Duty Actuators
Heavy-duty actuators utilize several power sources depending on the load they are handling and the amount of torque output required from their end. The following power sources are generally utilized:
- Hydraulic
The traditionally preferred source of power, hydraulic power sources are used for their ability to provide high power output. Even with other types of actuators being produced with phenomenal strength and functioning, hydraulic actuators are still preferred in many applications as seen in high-pressure butterfly valves.
- Electric
With development of technology, electric power sources are able to provide large amounts of power as well. They now display the ability to match up to the demanding requirements of heavy duty applications. Hence, these systems are being employed more often due to their quiet operation, no leakages, and comparatively cooler functioning.
- Pneumatic
These actuators are used for their high-speed operation, robust design, and high torque outputs. Pneumatic actuators are comparatively more compact in design but perform just as efficiently.
Industrial heavy-duty actuators are available in linear and rotary types providing motion that is most compatible to the working of the application. They also feature corrosion resistant components and are capable of producing up to and over 1000 pounds of pressure. In extreme and unique conditions, some heavy-duty actuators are capable of producing over 5000 pounds of pressure. These actuators feature robust designs and components that are capable of long service lives. They are also designed in a manner to keep contaminants away from the inner components of the machine. The different types of hydraulic, electric, and pneumatic actuators are utilized in industries according to their capabilities and the applications.
