ATI Limit Switches

Performance Highlights




ATI offers a full array of limit and proximity switches to meet any application. The switches are rigidly attached to the actuator using custom-designed switch brackets. The rigid construction ensures accurate reading of the valve travel limits even in the harshest conditions.

For close-coupled applications, where the piston rod is applying force directly to a valve or damper, there may not be space to allow for conventional switches triggered by a tail rod or valve coupler. In this case, ATI offers fiberglass cylinders with magnets triggered by the piston movement inside the cylinder. Alternatively, an LVDT could be used.

Our Client


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.

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