Severn

What Severn does

Severn is a UK-based industrial engineering company founded in 1961 that designs, manufactures, and supports high-performance flow control products for the global energy industries. Its core product portfolio spans four valve families — control globe valves, choke valves, butterfly valves (including the patented Oblique Cone Technology / OCT 8500 series), and a full range of pneumatic, hydraulic, electric, and electro-hydraulic actuators — augmented by proprietary add-on technologies: TrimGuard choke valve trim protection (validated to exceed 700J impact resistance), SPIRES on-stream emergency sealant injection for butterfly valves, and HIPPS (High Integrity Pressure Protection Systems) as SIL 3-capable safety instrumented systems aligned to IEC 61508/61511. The company also operates comprehensive in-house testing facilities, including cryogenic testing for LNG service, and delivers lifecycle enhancement services spanning maintenance, refurbishment, re-engineering, and long-term valve management contracts (e.g., a 14-year North Sea contract with a 5-year extension).

Severn's business model is a sales-led, engineering-intensive enterprise model: bespoke valves are specified and priced per project against materials (Carbon Steel through Inconel/Titanium), pressure class (#150–#2500), trim configuration, actuation, and testing requirements, with multi-year contracts underpinning lifecycle services. Customers are exclusively large operators, FPSO vessel owners, EPCs, and NOCs across Oil & Gas, LNG, Petrochemical, Power, and Offshore & Maritime verticals, with named reference accounts including Saudi Aramco, Dana Petroleum, Tullow/MODEC (Jubilee FPSO), and DSME Korea (FSRU BW Magna). Manufacturing is located in the UK (Brighouse, Stroud, Gloucester) and India (Chennai), with operational/service hubs in Aberdeen, Houston, and Dubai, and a localised manufacturing partnership with SMI in Saudi Arabia following 9COM approval in January 2026.

Following the December 2025 acquisition by Finland-listed Valmet Corporation and the simultaneous acquisition of US-based ValvTechnologies, Severn operates as a subsidiary within a larger industrial group, with an explicitly stated objective of expanding its global manufacturing footprint in India and the USA. The combined entity now spans 501–1,000 employees, with revenue not publicly disclosed.
