The ATI Emergency Shutdown module is designed to provide reliable self-contained automatic control of pipeline valves based on pressure at the sensing point. This control module can be set up for automatic valve opening or closing depending on operational requirements. Many customers utilize this control module in conjunction with ATI’s Automatic Line Break Control module to provide a redundant shutdown function. Pressure is sensed and control action initiated through a diaphragm-operated hi-pressure pilot valve. The diaphragm pilot valve trip setpoint can be adjusted over a wide range of operating pressures. Once the line pressure drops below the setpoint, the diaphragm pilot valve applies pilot pressure to the primary poppet valve and the appropriate valve action is initiated. Utilizing the pipeline gas for both the pilot gas and power media makes the control system independent of regulator and other power source failure. The design simplicity utilizes minimal components and ensures the valve operates only when required. This control module can be integrated with other control modules, such as the Remote Electric Control module, to achieve various desired operational control strategies.

ATI Emergency Shutdown Systems Performance Highlights
  • Hi-pressure construction – no regulator, relief valve, or mechanical switching valve.
  • All components constructed of corrosion resistant marine-grade, hard-anodized aluminum or stainless steel.
  • Easily adjustable trip setpoint.
  • No mechanical linkages, which are subject to environmental failure.
  • Limit valve ensures complete opening or closing of the valve.

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.
