The ATI Automatic Station Bypass is designed to keep gas flowing in the event there are major compressor problems. This control solution was developed with reliability as the primary objective to ensure the Bypass Valve opens only when it is necessary. To achieve this objective, the proven Poppet Valve is combined with a reliable, differential pilot valve to form a stand-alone control module. The differential pressure valve monitors the suction and discharge pressures of the compressor station. When the differential drops below the adjustable setpoint, pilot gas is passed to the pilot of the poppet valve and control action is initiated. Utilizing the pipeline gas for both the pilot gas and power media makes the Automatic Station Bypass control system independent pf regulator and other power media failure. The design simplicity and minimal components ensure the bypass valve opens only when required. The Rate-of-Drop calibration kit provides accurate calibration of the trip point, as well as simulation of various operational failure scenarios for testing control action.

ATI Bi-Directional Station Bypass Actuator Control Performance Highlights
  • Hi-pressure construction – no regulator, relief valve, or mechanical switching valve
  • Differential pilot valve utilizes a stainless steel diaphragm for accuracy and repeatability
  • Marine grade, hard anodized aluminum body for both poppet and differential pilot valves
  • Easily adjustable differential trip set point (1.0 psi to 14.5 psi)
  • No mechanical linkages, which are subject to environmental failure
  • Limit valve ensures complete opening of bypass 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.
