Linear Pneumatic Actuator Performance

  • Our L series actuator is perfect for control valves. With smooth operation from speeds as slow as .012 inches per second to as fast as 12 inches in less than a second.
  • Our HDL series actuator is ideal for on/off applications.
  • For anti-surge applications and other high speed applications, a cushion design is incorporated inside the piston cylinder assembly.
  • The adaptable nature of our design allows you to automate valves in place without shutting the plant down.
  • Our pneumatic actuators can accommodate a broad spectrum of valve applications from very high to very low thrust requirements.

Spring Return Actuators Highlights

  • To provide proper failure position, ATI spring cartridges allow for fail open or fail closed valve applications. This is extremely important in emergency shutdown applications.
  • A spring is the only true mechanical failure method. However, an air fail system can provide a cost effective failure mode solution when using a double acting actuator and an air tank.

Spring Return Explanation

Spring Return Standard Specifications

  • Bore Size 4" thru 44"
  • Stroke 1" thru 22"
  • Maximum Working Pressure 150 psi
  • Static Pressure Test 225 psi
  • Thrust 500 lbs to 50,000 lbs
  • Temperature Range Standard -40º F to 200º F Low Temp -65º F to 200º F High Temp -20º F to 400º F

* Larger bore sizes, longer strokes and higher pressure are available.

Double Acting Actuators Highlights

  • The design of our double acting actuators minimizes height and maximizes thrust.
  • force = supply pressure * area
  • area = .7854 * (piston diameter)^2
  • In order to double the force for a given pressure, you need only to increase the diameter by a factor of 1.41.
  • This design is superior to a tandem or a stacked cylinder design where the same increase in force would require increasing the effective piston diameter by a factor of 2. This requires more material which increases the price.

Our Client

Testimonials

I was impressed and quite thankful for ATI’s commitment to get the job done on time and with a high level of quality.

Konrad M. Fontenot, Engineering Section Group Lead, Exxonmobil Beaumont

ATI has been supportive when we have had questions and their product has worked well for us. If the application came up again where we had the choice of using the ATI actuators, I would recommend getting them.

,

All of our switching valves for our mole sieve beds are orbit valves fitted with ATI actuators. These have been in service for ~8 months now and have had no issues.

,

ATI was very supportive during this project with helping us when we had to retrofit the actuators to the valves during a quick series of valve replacements.

,

We have 14 of your actuators at this facility, with a clean rack record for over a decade.

Maintenance Team Member, Industrial Gas Supplier

I really appreciate the commitment to deliver the needed products on a very short schedule.
