Electric Actuator Valve Vs Pneumatic

Pneumatic actuators use air or another gas pressure as the primary power source to produce motion which in turn controls the valve.

Electric actuator valve vs pneumatic.

It may sound frivolous but choosing the right actuator technology is a lot like choosing a role playing game character. The solenoid valve is controlled by either an ac or dc voltage. Pneumatic vs electric actuators since their technologies are so different determining whether to choose a pneumatic or electric actuator for a process system may seem confusing. Both involve a 3 way compromise.

Force and speed on pneumatic actuators are easily adjustable and are independent of each. The difference between pneumatic and electric actuators is that the electric motor is part of the actuator assembly rather than separate. Pneumatic actuators require an air supply of 60 to 125 psi. In the most common type of pneumatic actuator the diaphragm actuator air is pumped into a hollow casing where the resulting pressure acts on a flexible rubber diaphragm to deflect it from its original position.

Electric actuators are most commonly available with 25 percent duty cycle. When no air supply is available electric actuators. What do actuators and video game characters have in common. Read on to find the basic points of difference between an electric and pneumatic actuator.

Tradeoffs between electric pneumatic and hydraulic actuators. The biggest difference between electric and pneumatic actuators is the driving force of their operation. Once applicable to light duty work that s now changing. The electric motor is part of the actuator instead of being separate like a pneumatic or hydraulic system.

Typically electric actuators are known for their high levels of precision while pneumatic actuators are considered less expensive and easier to maintain. Electric actuators use mechanical components like lead screws and gears to open and close their applications. Before specifying a pneumatic or electric actuator for valve automation it is important to consider a few of the key performance characteristics of each. Pneumatic actuators have a 100 percent duty cycle.

The case for pneumatic actuators pneumatic actuators provide high force and speed at low unit cost in a small footprint. An electric actuator is the one which makes use of electrical energy to produce mechanical energy. This requires a larger actuator since it has to overcome the force of the spring in addition to providing enough torque to operate the valve. In fact the harder they work the better they work.

The fighter mage and thief are classic character archetypes in video. As a matter of fact pneumatic cylinders provide more force and speed per unit size than any other actuator technology except hydraulic.
