The Difference Between Pneumatic and Electrical Actuator Systems

Deciding on your valve automation solutions is no easy task. There are many factors to consider when making this decision. If you choose wrong you waste time and money. If you pick correctly you'll be sure to have dependability and seamless productivity. This is especially the case when working in certain harsh environments. This is why you most consider side-loading options or if you need seal life. The working conditions you are operating in should be the deciding factors as to how you determine your solution. Ideally, you want to reduce failures or MTBF (mean time between failures). Understanding your job will help you understand the solutions you need.

What about pneumatic and electrically actuated timing systems? There is a difference between the two, and depending on the job, you will pick different actuators. Pneumatic timers have withstood the test of time. They have been updated, meaning that they have had digital technologies added too them. This has only made the systems better; however, just because these systems have been used for a long time doesn't mean there aren't without there downside. Most experts would say that this system has three specific shortcomings. The first is operative expenditures, the second is system maintenance, and lastly there is controllability. The three problems all lead back to the fact the system works with air. Compressed air isn't free, and it happens to require a lot of energy to move it around. There is also the issue of leaky connections, keeping the air clean/dry. Having to reduce air friction can be overwhelming and costs time and money.

Pneumatic timers are great options for when simplicity and quickness is needed. Their load capacity is extremely high, and the product works quicker than an electrical actuator.

Electrical actuators have an easy interface with electrical control systems, and this is why you will usually find these actuator systems in automation applications. The actuator and the controller are guided both from the same power supply, but they do have longer cycles than their counter part.

There are downsides for both of these actuator systems, and so the only real way to tell which would work best for you and your company is to fully understand the project your are trying to finish. Talk with a local company about your issues and come to a solution that works for you.
