Actuator controls start, stop, and protect actuators from overload and excessive cycling. Simple manual or automated stop/start systems are used for single function roles, while multifunctional servo systems are used for complex installations. Actuators need to be started and stopped manually or automatically, and actuator controls can be simple or complex. Simple systems can be […]
A ball screw actuator uses a precision machined lead screw and ball bearings to provide high thrust, linear load movement. The balls are arranged to match the pitch of the nut threads, causing the nut to move up or down its length. The actuator produces linear or rectilinear output motion from a rotating input, making […]

Actuators activate mechanical devices and come in different designs such as wheel and axle, pneumatic, hydraulic, solenoid, screw, and manual. Choosing a design depends on cost, purpose, long-term goals, and mechanical strength. Multiple actuators may be used for performance optimization. Wheel and axle designs are for interchangeable rotational and linear forces. Pneumatic designs are low-cost […]
Control valve actuators precisely position valves for adjustable control in the chemical process industry. Pneumatic actuators are preferred due to simplicity and low cost, but electro-hydraulic and electric actuators are also used. Valves can be air-to-open or air-to-close, and engineers must consider instrument air leakage for process safety. Manual actuators are cheaper but less accurate. […]
Piezoelectric linear actuators use the piezoelectric effect to convert electrical current into motion in a crystal. There are two types: stepping and continuous acting. Layering crystals can result in larger movements, and reversing polarity can cause the actuator to move in the opposite direction. Some crystalline structures give an electric charge when stressed or twisted, […]
A wireless actuator receives its activation signal or power supply via a wireless link, using radio waves or magnetic induction. It is used in industrial automation, manufacturing, and household applications, providing greater mobility and security. There are two types of actuators: power switching and contact switching. The wireless actuator eliminates the need for cables, enhancing […]
A pressure actuator responds to pressure changes in a cylinder, activating systems connected to the device. It can be found in various devices, including cars and sprinkler systems. Regular inspections are necessary for maintenance, and technicians can replace malfunctioning components. Precautions should be taken before work is started to reduce the risk of accidents. A […]
Piezoelectric actuators use the piezoelectric effect to create mechanical stress in crystals, resulting in precise motion at the micro- or nano-scale. They have various designs and are used in industries such as aerospace, medical, and nanotechnology due to their low power consumption, lack of magnetic fields, and durability. The piezoelectric actuator is a form of […]
Actuator positioners adjust actuators based on real-time system requirements using inputs from sensors. They are used in various applications, such as naval gun turrets and flow control valves. These systems consist of a full-range actuator, a controller, and an interface unit that compares ideal situations with the actuator’s position and corrects any discrepancies. An actuator […]
Vane actuators use a straight vane in a sealed chamber to provide actuating motion for valves. They can be single or double-sided, with multiple vanes. They are used to operate large quarter-turn valves and are capable of bidirectional movement. The motion is transferred to the secondary mechanism through the shaft attached to the paddle. A […]
Actuator arms transfer the motion of actuators to the device they operate. They can be part of the internal mechanism or separate linkages, with fixed or articulated joints. Actuators range in size and use various driving mechanisms. Actuator arms can be short or long and may require support. The term can also refer to pick […]
Actuator torque is the amount of twisting force an actuator can produce. It determines the range of loads the actuator can handle, with higher torque allowing for a wider range. Torque is also important in tools and vehicles, where it affects performance. Actuator torque is a quantitative expression of the amount of torque an actuator […]
A remote actuator is a device that provides motion to activate a secondary mechanism from a distance.
