IMI Provides Digital Valve Controls for Alaskan Pipelines
(P&GJ) — IMI is ready to deliver 15 QuickTrak Digital Valve Control System and Positioners for one of the world’s largest oil pipelines, which spans approximately 800 miles (1,287 km) across Alaska, marking a significant step forward in enhancing the efficiency and safety of this piece of critical infrastructure.
The system features pneumatic digital valve control technology, combining a microprocessor-based control system with an integrated valve positioner. It will provide the Alaskan pipelines with the control and performance of a hydraulic system, but without the storage and environmental requirements. The system can be relied upon in extreme temperatures, operating from -40° C to 70° C.
It features three sequential layers of safety through integrated software, firmware and mechanical systems. It also benefits from a probe consisting of Magneto strictive linear position transducers located within the actuator stem to provide fast and highly accurate control feedback. Additionally, it features a custom designed actuator with larger ports to accommodate the feedback probe.
“Effective monitoring is critical to ensuring the safety and efficiency of pipelines, which is why we approach it with the utmost seriousness,” Patrick Deane, business development Director at IMI, said. “The QuickTrak Digital Valve Control System represents a significant innovation in the energy infrastructure sector and underscores IMI’s commitment to advancing the digitisation of the oil and gas industry.”
The systems are engineered, designed and built to robust, fail-safe designs – and as such are ATEX, IECEx, CSA and UL certified. These qualities and certifications make them well-suited to demanding operating conditions. They also incorporate digital control, using a closed-loop system based on the value and spool position to control the stepper motor, adjusting the actuator’s chamber pressure to achieve the desired valve position.
Their deployment in Alaska is a testament to the dedication, ingenuity, and engineering excellence of our team, as well as the collaborative effort that brought this project to life.
