Both involve a 3 way compromise.
Electric actuator valve vs pneumatic.
Read on to find the basic points of difference between an electric and pneumatic actuator.
In fact the harder they work the better they work.
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.
The solenoid valve is controlled by either an ac or dc voltage.
While the electric linear actuator provides high precision it does have large spacing.
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.
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.
It may sound frivolous but choosing the right actuator technology is a lot like choosing a role playing game character.
The case for pneumatic actuators pneumatic actuators provide high force and speed at low unit cost in a small footprint.
Once applicable to light duty work that s now changing.
Spring return pneumatic actuators use compressed air to move the piston in one direction and a spring to push it back in the other when the air is stopped and allowed to vent.
Tradeoffs between electric pneumatic and hydraulic actuators.
An electric actuator is the one which makes use of electrical energy to produce mechanical energy.
Pneumatic actuators have a 100 percent duty cycle.
The biggest difference between electric and pneumatic actuators is the driving force of their operation.
As a matter of fact pneumatic cylinders provide more force and speed per unit size than any other actuator technology except hydraulic.
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.
The difference between pneumatic and electric actuators is that the electric motor is part of the actuator assembly rather than separate.
Force and speed on pneumatic actuators are easily adjustable and are independent of each.
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 require an air supply of 60 to 125 psi.
While a pneumatic actuator is an air operated actuator which converts air pressure into mechanical force to operate the valve.
The electric motor is part of the actuator instead of being separate like a pneumatic or hydraulic system.
What do actuators and video game characters have in common.
Pneumatic actuators use air or another gas pressure as the primary power source to produce motion which in turn controls the valve.
