What Koso America does

Koso America, doing business as KOSO Hammel Dahl, is a US-based manufacturer of industrial control valves, pneumatic linear actuators, and accessories for process automation. The entity carries the HAMMEL DAHL brand heritage established in 1948 and operates as a subsidiary of Japanese strategic operating company Nihon KOSO, with corporate headquarters at 253 Pleasant Street, West Bridgewater, Massachusetts and a headcount of 101-250 employees. The company specializes in valves engineered for extreme operating conditions, including cryogenic services down to -450°F for LNG applications, high-pressure compressor and booster pump stations, and erosive and slurry service in metals, minerals, and pulp and paper processes.

Its product portfolio comprises the G100 Series general service globe and angle valves (G110, G120, G130), the V510/V520 and V800/V801 top- and bottom-guided double-seated globe valves, the V701 Venturi Seat Angle Valves for slurry and erosive service, the V817 Cryogenic Cold Box Globe Valves, the D/R Series and D52/R52 Series spring-diaphragm pneumatic linear actuators, and the proprietary VeCTor™ Velocity Control Trim used in power generation boiler feedwater recirculation, bypass, and steam turbine bypass applications. The company holds ISO 9001:2015 quality management certification and serves chemical processing, power generation, industrial gas, oil and gas (including LNG), metals and minerals, and pulp and paper customers.

Revenue is generated through direct enterprise hardware sales of valves, actuators, and accessories, with quote-based pricing that is not publicly disclosed. Distribution is executed through a multi-tier representative network covering the United States, Canada, International markets, and a dedicated Nuclear Industry Representative channel. End customers are industrial owner-operators and engineering, procurement, and construction contractors specifying valves into process plants, with the company positioning on extreme-service reliability and customization rather than commodity volume.
