What is an Electric Actuator?
A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem.

Who supplies actuators in South Africa?
Horne Technologies is able to supply almost all kinds of actuators, linear and rotary, as well as 6-axis parallel kinematic systems, regardless of size and power, however, we specialize more in high accuracy, smaller systems, for military, space, scientific, optical and precision applications.
What causes an actuator to go bad?
Normally, failure is caused by application errors, such as side loading, incorrect wiring, poor mounting fixity, excessive loading, and exceeding duty cycle.
How long do valve actuators last?
To summarize, mechanical equipment such as shutdown valves, control valves, actuators, and accessories such as positioners are designed keeping in mind a plant’s life of around 25 years.2
Are electric actuators reliable?
Electrical actuators can be safer and predictable in an emergency stop application since they don’t depend on trapped air to hold the cylinder in place. The load can be held more reliably also since there is no air leakage between the cylinder and the valve.
What is the strongest actuator?
hydraulic actuators
Load capacity.
Unlike electric linear actuators, hydraulic actuators are suited to high-force applications and are customizable to almost any weight. They are also the most powerful actuators on the market and are suitable to work under heavy pressure.
How fast are electric actuators?
While 5”/sec is considered a fast speed for actuators, there are linear actuators capable of reaching faster. The PA-15 is a super-high-speed linear actuator capable of reaching up to 9.05″/sec with the slowest pace of 3.20″/sec, a rate still considered quite impressive.
Where are electric actuators used?
They are used in materials handling for operations such as servo presses and clamping and are widely used in the packaging sector.
Their benefits in accuracy, flexibility and low operating costs lead to use in robotics, electronics and electronic assembly, machine tools, and many other industrial sectors.
