What NAF does
NAF Control Valves (legal entity ANDRITZ NAF AB) is a Swedish manufacturer of industrial control valves for demanding process applications. The company was founded in 1899 (with its defining innovation — development of the world's first ball valve — dated to 1933) and is headquartered in Norrkoping, Sweden. NAF's portfolio spans ball valves (Duball DL, Trunnball DL, Triball, ceramic-lined variants), check valves, ball sector valves (Setball series), butterfly valves (Torex, Unex), capping valves (ProCap), actuators (Turnex, RC), smart valve positioners (LinkIT) and selection software (eValuate). End markets served are pulp & paper (its historical stronghold), chemical processing, power generation, oil & gas, and water treatment — all segments requiring precise fluid flow control under high temperature, pressure or corrosive media.
The company sells on a quote-based, project-driven basis to enterprise customers via direct field sales supported by a global distributor extranet. Following the May 2024 acquisition by international technology group ANDRITZ, NAF's distribution has been absorbed into ANDRITZ's global network, automation stack and EPC delivery channels; its products are positioned as a default fit inside ANDRITZ process equipment packages. The model is fundamentally an industrial-equipment one-time sale plus multi-year service and spare-parts contracts, with aftermarket lifecycle support emphasized as a key retention mechanism.
Revenue is not publicly disclosed and headcount sits in the 51–100 employee band, implying a mid-sized niche industrial supplier rather than a high-volume player. The combination of century-old specialized IP, EPC channel access through ANDRITZ, and a deliberate push into digital position feedback (LinkIT) and oil & gas decarbonization verticals defines NAF's current strategic posture as a specialist consolidating within a larger industrial group rather than an independent scale challenger.
