How do I choose an actuator?
Four Steps to Choosing the right Linear Actuator
- Step 1: Determine the amount of force required.
- Step 2: Determine the distance the actuator needs to move.
- Step 3: Determine the speed required.
- Step 4: Based on your project choose a type of Linear Actuator.
How do I choose an electrical actuator?
Selecting an electric actuator Start with the motion profile. This establishes the demands for velocity and time as well as force (or torque) and the required travel distance. This is also the place to determine the maximum stroke needed as well as maximum and minimum speed requirements. Then calculate the load.
Which actuator is best?
Best Linear Actuators
| Best Linear Actuators | Capacity | Length |
|---|---|---|
| Homend Stroke Linear Actuator | 225 lbs | 300 mm |
| ECO-WORTHY Solar Tracker Linear Actuator | 330 lbs | 450 mm |
| Justech Linear Actuator Motor | 160 lbs | 100 mm |
| WindyNation Stroke Linear Actuator | 225 lbs | 750 mm |
How do I choose a valve actuator?
How to Select an Actuator for Valve
- Move the valve closure member (disc, ball, or plug) to the desired position.
- Hold the valve closure member in the desired position.
- Seat the valve closure member with sufficient torque to provide the desired shutoff specification.
- Provide a failure mode in the event of system failure.
What size linear actuator do I need?
The distance you need to move an object with a linear actuator is your stroke length requirement. But for the most part, once you know the distance you want your linear actuator to move, you should choose an actuator with a stroke length at or above that value.
Is a valve an actuator?
A valve actuator is the mechanism for opening and closing a valve. Manually operated valves need someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. To begin with, valve actuators are a type of control valve.
What is actuator used for?
An actuator is a device that uses a form of power to convert a control signal into mechanical motion. From electric door locks in automobiles, to ailerons on aircraft, actuators are all around us.
What is an actuator used for?
What are the different types of actuators used for?
Here is a list of the various types of actuators: As the name implies, electric linear actuators use electrical energy to enable movements in a straight line. They work by moving a piston back and forth based on electrical signals and are mostly used for movements such as pulling, pushing, blocking, lifting, ejecting, clamping, or descending.
What is the purpose of a hydraulic linear actuator?
The purpose of a hydraulic linear actuator is the same as that of an electric linear actuator – to generate a mechanical movement in a straight line.
Which is the best rating for a valve actuator?
The most common ratings for valve actuators (and solenoid valves on pneumatic acutors) are NEMA 4/4X and NEMA 7.
Can a pneumatic valve be used with an electric actuator?
Electric actuators have basically the same common characteristics as pneumatic with the exception of the NAMUR mounting for solenoids since they are not used on electric actuators. For rising stem valves there are electric actuators that operate with a screw drive.
