IMI Truflo Marine are an established supplier of valves, actuators and air stations to the naval marine and nuclear markets within the UK and overseas.


IMI Truflo Marine has been a specialist in the design and manufacture of high integrity valves, actuators and pressure reducing stations for critical nuclear and naval marine applications for over 50 years. Our products have an outstanding reputation for integrity and reliability in extreme applications, and we provide support through the life of a facility, from concept to decommissioning and disposal.

Critical applications

  • Naval marine
    With over 120,000 valves in service in 24 navies worldwide, we have extensive knowledge and ex-perience in designing and manufacturing valves for the naval marine industry. Our valves have the high flow capability and quick shut off vital to the functioning of critical systems on board. We can supply valves for any system on board a submarine or surface ship.
  • Nuclear
    We offer specialist component manufacture, including machining, fabrication, welding and assem-bly to nuclear partners, supporting nuclear fuel fabrication, reactor internals and support services. Top entry ball valves have been supplied to the nuclear sector for over 35 years, with nuclear valves installed on most of the UK nuclear fleet and as far afield as Sweden and Russia.

Key technologies

  • Hull Valves
    We have a range of high quality hull isolation valves, including both end entry and top entry solu-tions, in a range of sizes and materials. Our base range of hull valve bodies are machined from a forged billet using Aluminium Bronze for the best performance under testing conditions.
  • Top Entry Ball Valves
    Our top entry ball valves have a proven history of service on submarines and in nuclear power sta-tions. We offer a range of materials to suit different applications, with interchangeable seat materi-als. We can also provide customers with qualified pressure, life cycle, shock and seismic testing to customer specifications.
  • Hydraulic and Pneumatic Actuators
    Our bespoke actuators are precision-engineered, dependable and corrosion resistant. We offer double acting and spring return models, which have proved their value in the most demanding en-vironments. The range has been performance tested against extreme vibration and shock re-sistance.

Aftermarket services

Our through life support packages provide enhanced material availability through stock holding and expedited production to meet urgent emergent requirements. In house trained specialists are available to carry out on-board inspections and repair services. A streamlined strip, survey and repair service provides fully traceable repairs and testing to customer specifications.
