ATI Manual Overrides

Industries

ATI offers four manual overrides for operating our valve actuators.

JS-1 – single-acting mechanism that extends the actuator piston rod when operated. Intended for infrequent use.

JS-2 – Capable of extending or retracting the actuator and can be engaged at any position from fully open to fully closed. Since the entire manual override mechanism is incorporated into the actuator adapter bracket, the power cylinder can be serviced or removed while maintaining complete control of the valve.

HO-1 – A one-way hydraulic override for use on spring-return actuators. This override compresses the spring and operates the valve. The spring force is used to move the valve to the failure position.

HO-2 is used on double acting actuators and is capable of extending or retracting the actuator. The HO-2 also allows for very precise speed control by regulating the flow of the hydraulic fluid in the system.

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.
