IMI Delivers Record-Sized Choke Valves

IMI Achieves Milestone with World’s Largest Production Choke Valves for North Sea Platform

September 18, 2025

Record-Breaking Valve Delivery

IMI has completed delivery of unprecedented choke valves to a North Sea platform. These represent the largest production choke valves ever manufactured. The unmanned processing platform marks a significant industry advancement.

Engineering Specifications

The 100D DRAG multi-stage control valves measure 20×20 inches. They carry an ASME 4500 rating with 686 barg design pressure. Forged ASTM A182 F22 Cl materials form the valve body and bonnet. Additionally, Inconel 625 weld overlay provides superior corrosion resistance.

Advanced Technology Implementation

IMI’s patented DRAG technology incorporates solid tungsten carbide trim. This ensures exceptional durability under extreme conditions. Therefore, the valves withstand highly erosive, high-pressure environments effectively.

Quality Assurance Process

All three 100D DRAG valves passed rigorous factory acceptance testing. The Austrian production facility verified every performance parameter. Consequently, the equipment meets the highest quality standards.
