Linear Hydraulic ACTUATOR PERFORMANCE

  • Our H series actuator is ideal for control valves especially when it incorporates the ATI hydraulic positioning system.
  • Our HDH series actuator has been effectively used for on/off applications such as steam blow applications that require very fast opening speeds.
  • The adaptable nature of our design allows you to automate valves in place without shutting the plant down.
ATI Linear Hydraulic Actuators Performance Highlights

Linear Hydraulic Spring Return Actuators

  • Actuate any rising stem valve
  • True Mechanical failure mode
  • Precision machined steel cylinder heads maintain linearity
  • Springs pre-compressed and welded into sealed spring cartridge at the factory for safe, maintenance-free service
  • Spring rates customized for maximum stiffness
  • Hydraulic actuator inside the unit, which reduces height
  • Travel stops in place to protect valve and stem.

Our Client

Testimonials

In all of the readiness reviews that I have conducted, ATI is by far the most well-prepared. The organization has built a solid foundation, and is off to a healthy start to the new [ISO 9001:2015] standard; ATI has clearly taken a serious approach to addressing the risks of its business and handling mitigation in a controlled manner.

Tom R., , Independent Auditing Agency

ATI linear actuators on 6-inch and 8-inch gate valves have worked flawlessly since put in Y-grade liquid service in 1994.

George Ford, Engineer, Enterprise Products

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.
