What SEVERN GLOCON GROUP PLC does

Severn Glocon Group PLC (operating as Severn Valves) is a British specialist manufacturer of high-performance severe-service flow control valves for the global energy industries, founded in 1961 and headquartered in Gloucester, United Kingdom, with manufacturing operations across the UK, India, and (most recently) the USA. The company designs, manufactures, and supports bespoke control valves (1000, 1200, 1200P, 1600, 3000, 4000, 5000, and 7000 Series), choke valves, butterfly valves, and actuators engineered for extreme pressure, temperature, cryogenic, and corrosive service conditions. Proprietary technologies include TrimGuard choke impact protection (validated to 700J), SPIRES on-stream butterfly valve repair sealant injection systems, and OCT-SW triple-offset seawater-service butterfly valve designs with patented graphite-isolation to prevent galvanic corrosion. Severn also supplies HIPPS (High Integrity Pressure Protection Systems) engineered for SIL 3 overpressure protection in LNG plants.

The business serves oil & gas (upstream, midstream, downstream), petrochemical, power generation, LNG (liquefaction, regasification, FSRU/FLNG), and industrial gas customers — with reference installations at Saudi Aramco, MODEC/Tullow (Jubilee FPSO), Dana Petroleum, Ichthys LNG, Gorgon LNG, Yamal LNG, and BW Magna FSRU. Revenue is generated primarily through direct enterprise field sales of bespoke-engineered valves and multi-year valve management / lifecycle service contracts (the company holds a 14-year North Sea valve management contract extended for a further 5 years), supplemented by licensed regional manufacturing partnerships under the 9COM framework (e.g., Saudi Mechanical Industries Co.) and licensed retrofit/repair arrangements (e.g., Adyard Abu Dhabi). On 1 July 2026 the company was acquired by Finland-based Valmet Corporation and now operates within Valmet's Flow Control segment focused on severe service applications.
