IMI Delivers ‘Largest Production’ Choke Valves to Landmark North Sea Unmanned Production Platform

IMI has successfully delivered what are considered to be the largest production choke valves manufactured to a landmark unmanned processing platform in the North Sea.

The 100D DRAG multi-stage, multi-turn control valves were manufactured at the company’s IMI CC production facility in Austria. They measure 20” x 20” and are rated to ASME 4500.

The valve body and bonnet comprise of forged ASTM A182 F22 Cl with a design pressure of 686 barg. A full internal Inconel 625 weld overlay offers additional corrosion resistance. Leveraging IMI’s patented DRAG technology, the trim is made from solid tungsten carbide to provide extreme durability in high-pressure, erosive service.

Following the successful completion of factory acceptance testing, three 100D DRAG valves have so far been delivered to the site.
