Actuators are mechanical or electro-mechanical devices that provide controlled and sometimes limited movements or positioning which are operated electrically, manually, or by various fluids such as air, hydraulic, etc. Two basic motions are linear and rotary. Linear actuators convert energy into straight line motions, typically for positioning applications, and usually have a push and pull function. Some linear actuators are unpowered and manually operated by use of a rotating knob or hand wheel. Rotary actuators convert energy to provide rotary motion. A typical use is the control of various valves such as a ball or butterfly. Each actuator type has versions for various power configurations and come in many styles and sizes depending on the application.

Linear chain actuators provide push and pull motions with rigid chains.

Linear chain actuators are used primarily in motion control applications for providing a straight line push or pull motion.

Manual linear actuators are used primarily in commercial applications for precise positioning such as manipulating tools or workpieces.

Kris Power Pump Linear

Manual actuators are unpowered and use a rotating knob or hand wheel to operate. There are several types including those with lead screws, racks and pinions, belt drive, etc.

Each having its specific load and drive force capability. Thermo-mechanical actuators are another type and operate by means of thermal expansion, usually on a micro scale. Manual Rotary Manual Rotary Actuators are mechanical devices providing rotary output through the translation of manually rotated screws, levers, or gears, and are usually composed of hand operated knobs, levers, or handwheels, gearboxes or threaded nut mechanisms, and output shafts. Key specifications include the intended application, drive method and mechanism, mounting configuration, valve type, if applicable, as well as physical dimensions as required. Manual rotary actuators are used primarily for the operation of valves.

They are also known as manual valve actuators or valve operators. Valve types can include ball, butterfly, check, and globe valves. Other applications may include any that require limited and controlled rotational movement.

Applications and Industries Powered actuators generally incorporate motors, cylinders, or other motion devices to produce rotation or linear translation. Rack and pinion arrangements, ball screws, and other kinds of power transmission components connect the motors, etc. To the loads. Actuators are segregated by motion and power source.

Linear actuators produce push/pull action. Rotary actuators produce rotational motion.

Pneumatic Linear Actuator

In many cases, linear actuators begin with a rotary prime mover—a motor, typically—whose rotation is converted to linear motion through a power screw or similar device. The opposite is also true: many rotary actuators can begin with linear devices such as hydraulic cylinders which produce circular motion through rack and pinion arrangements. Actuators are used extensively to operate valves remotely. A valve so equipped is termed a control valve. (see Valves Buying Guide for discussion of control valves.) A typical actuator for a globe valve needs to be capable of turning the valve stem through its many revolutions between open and closed.

Often a globe valve actuator will consist of an electric motor that drives a worm gear which in turn rotates a nut that engages the threads of the valve operator stem. Quarter-turn valves such as ball valves often use pneumatic actuators to push and pull racks past pinions which impart rotary motion to the valve ball, butterfly, etc. In short, valve actuator designs are closely aligned with the design of the valve they are intended to operate.

Actuators are also used in many linear motion applications where air power is not available to drive cylinders or where extra force is needed from compact designs. One unusual linear actuator uses chain which when straight forms a rigid length but which can curve around the driving gear to obtain its motion. Other linear motion actuators use toothed belts, lead screws, or rack and pinion sets, to achieve push/pull action.

Smaller linear and rotary actuators often employ direct drive voice coil motors. Linear actuators are used in packaging machines, medical equipment, production machinery, etc. As well as in a host of transportation industry applications from aircraft to rail. Linear actuators sometimes combine stepper motors with ball screws to achieve precise controllable positioning (left). Both linear and rotary actuators are available as manual models that serve as motion devices for slides, etc.

And as operators for manually operated valves. In some cases, manual valve actuators are used as override devices for control valves that are normally actuated with fluid or electric powered actuators (right). They are designed to declutch from the control actuators during normal automatic operation so as not to harm bystanders.

Considerations Picking powered actuators entails knowing such parameters as loading, stroke length, timing, etc. Many of these parameters have limits as to speed and force and narrowing the selection in this manner can bring the appropriate technology into focus. Other considerations include the kinds of services available. Hydraulic actuators provide large forces in small sizes but need a source of hydraulic pressure. Air powered actuators use readily available factory air but there is a tradeoff to be made due to their bigger sizes for equivalent forces. Electric actuators have advantages of better controllability and are less prone to leaking, an advantage in clean-room settings and more economical in the long run.

Electric actuators do tend to have appreciably higher first costs. They also have advantages in outdoor installation where air systems can freeze. Pneumatic valve actuators fall into two camps: double acting and spring return. Double acting means that air pressure moves the valve in both directions.

Spring return means that a spring is used on one stroke which the air pressure must overcome to open (or close) the valve. It makes a difference as to how the valve will behave upon a loss of air pressure. A spring return valve will return the valve to its unpowered state upon an air-pressure loss. Hydraulic valve actuators can be fitted in similar fashions.

For motion control, actuators are selected based on speed requirements and precision. Some linear actuators are designed for micropositioning and rely on piezo crystals to produce very small, high resolution motions which are useful in the nanometer world of optics, semiconductor manufacturing, etc. More typically, belt and ball screw based actuators impart motion to positioning stages and the like to achieve repeatability measured in thousandths of an inch. Some linear actuators are used with hand controls, such as those found in dental chairs, and do not require positional feedback other than end-of stroke limit switches. Some manufactures even eliminate these limit switches by providing integral freewheeling at the end of stroke, such as the actuators shown at right. Important Attributes Mounting Configuration This attribute describes the way in which the actuator attaches to the actuated device.

Valve actuators sometimes mount directly to the valve flange or use trunnion mounts to give access to valve stem packing glands. Relative advantages of each method are described in the reference cited below.

Actuation Features Selecting double acting or spring return here will choose the failure mode of the actuator upon loss of air or hydraulic pressure. Output Torque Output torque applies to both electric and fluid powered rotary actuators and describes the rotational force the actuator can apply to the valve to close it. It is usually expressed in in-lb. Maximum Extension/Retraction/Holding Force These attributes apply to linear actuators and may be sometimes be expressed as a single value such as maximum thrust force. They are usually given in lbf or N.

Maximum Speed For powered actuators, this is the highest linear or rotational speed the unit can deliver. It is usually expressed as rpm for rotary actuators and as in/sec for linear devices. Enclosure Protection Rating Electrical enclosures are specified in accordance with NEMA or IEC criteria for environment and ingress protection. Related Product Categories.
