Truflo Marine Ltd

What Truflo Marine Ltd does

Truflo Marine Ltd, operating commercially as IMI Truflo Marine, is a UK-based naval marine flow-control brand within IMI plc's IMI Process Automation division. The company designs and manufactures high-integrity isolation valves (ball, gate, globe, butterfly, check), hydraulic quarter-turn actuators, and pressure regulators/manifold valves for submarines and surface vessels, with engineering emphasis on saltwater corrosion resistance, UNDEX shock resilience, and extreme pressure/temperature endurance. Named customers include the Royal Navy (Astute-class at Barrow-in-Furness), the US Navy (attack submarine fleet availability), the Japanese Navy, and the French Navy.

Its core technology platform combines decades of naval valve qualification with proprietary additive-manufacturing capabilities — Laser Powder Bed Fusion (LPBF), electron beam welding, and Wire Arc AM (WAAM) — used to produce complex, biomimicry-inspired geometries that reduce lead times for specialized naval components. The 2024-patented Acoustic Control Vantage™ (ACV™) is an additive-manufactured trim that reduces fluid-borne noise and manipulates acoustic signatures for submarine stealth, developed through international collaboration with Japan, France, USA, and UK engineers during the COVID-19 pandemic.

The business model is enterprise field sales to navies, defense primes, and shipyards, with hardware sales complemented by a Marine Field Services Programme that delivers onsite inspection, maintenance, testing, commissioning, spares, and obsolescence management globally, including regional field service depots. A dedicated spare-parts cell at the Aston, Birmingham manufacturing facility has reduced lead times from up to 52 weeks to under 26 weeks for the longest-lead components. Primary segment is naval marine (defense); commercial marine is a secondary vertical. Manufacturing is centered in Aston, UK. Truflo Marine operates as a brand/division of publicly listed IMI plc (LSE: IMI); no standalone revenue is disclosed.

Core offering

Truflo Marine Ltd designs, manufactures, and supports high integrity isolation valves, actuators, and pressure reducing stations for naval marine applications on submarines and surface vessels. The product range spans ball, gate, globe, butterfly, and check valves, plus specialised equipment for weapons handling, cryogenic isolation, exhaust control, and ballast management, built to defence specification and qualified for allied submarine and surface ship fleets.

Product overview

IMI Truflo Marine is a product brand under IMI Process Automation specializing in high integrity isolation solutions for the naval marine industry. The company provides a portfolio of valves including ball valves (double ball marine hull, inline, floating), check valves, and general isolation valves, complemented by hydraulic actuators and pressure regulators. Products are engineered for extreme marine conditions including saltwater corrosion resistance, shock resilience for underwater explosions (UNDEX), and operation under extreme pressures and temperatures. Featured products serve applications such as weapons handling, cryogenic isolation, exhaust control, and ballast management. The portfolio also includes the innovative Acoustic Control Vantage™ (ACV™), an additive-manufactured stealth technology that reduces submarine acoustic signatures.
