Adams Armaturen

What Adams Armaturen does

Adams Armaturen GmbH is a privately held, family-owned German industrial valve manufacturer founded in Herne in 1960 by Karl Adams, who also invented the triple-eccentric (triple offset) metallic sealing system for butterfly valves that year. The company designs, engineers, and produces custom-tailored valves and metallic sealing systems for critical-service applications across power generation (fossil, nuclear, solar, geothermal, hydropower), oil and gas (including hydrogen, LNG, and FCC refining), petrochemical, district heating, water and wastewater, and metallurgy. Core products span tight shut-off, throttle, and control valves (MAK, HTK, OSK, WAK, DSK/ASK, MAKO, NSK), check valves (RZI, RZN, MAG, GMZ, FCV, SCV), combined-function valves (GZA, GBZ/AZI, MAG-S), and specialized hydropower and large-diameter units up to DN4200, operating across a temperature envelope of -253°C to +950°C and pressure ratings up to ANSI 2500.

The underlying technology stack combines the proprietary triple-eccentric sealing architecture with CAD/3D design (since 1982), FEM structural analysis, CFD flow simulation, and in-house cryogenic and high-temperature testing facilities. The MAKO special control valve trim extends the platform with flow-channel disc geometry that prevents cavitation and reduces noise. Manufacturing is anchored at the Herne headquarters and expanded through wholly-owned production entities in Switzerland (ADAMS Schweiz AG, specialized in hydropower) and the United States (ADAMS Valves Inc., Houston, inaugurated 2010), with regional sales entities in the Netherlands, India, Singapore, Australia, and Bahrain. The company is currently managed by Carina Borzek and Jan Schmidt as Managing Directors.

Adams generates revenue primarily through hardware sales of custom-engineered valves priced by quotation, supplemented by a spare parts and after-sales service stream that supports installed equipment in operation for decades. Distribution is direct-to-enterprise, selling to large industrial customers, power plant operators, refineries, and EPC contractors through its own subsidiary network rather than third-party channels. Marketing relies on international trade shows (including ADIPEC, Valve World, Chemtech), industry seminars, a multilingual corporate website, and active social media presence. The company holds ISO 9001 (since 1993), ISO 14001, ISO 50001, ISO 3834-2, DGRL 2014/68/EU, UKCA, and AD-2000 HP0 certifications, and self-describes as a 2021 world market leader in triple-eccentric valve technology.

Core offering

Adams Armaturen designs and manufactures custom-engineered industrial valves based on its proprietary triple-eccentric metallic sealing system, covering tight shut-off, throttle, control, check, and combined function valves for critical applications. The portfolio spans sizes from DN80 to DN4200 and temperature ranges from -196°C (cryogenic) to +950°C (high temperature), serving power generation, hydropower, oil & gas, petrochemical, district heating, water, and metallurgy industries through global direct sales subsidiaries.

Product overview

Adams Armaturen is a German industrial valve manufacturer and inventor of the triple-eccentric metallic sealing system. The company offers a comprehensive portfolio of butterfly valves organized into three main product lines: Tight shut-off, throttle and control valves (MAK, HTK, OSK, WAK, DSK/ASK, MAKO, NSK); Check valves (RZI, RZN, MAG, GMZ, FCV, SCV); and Combined function valves (GZA, GBZ/AZI, MAG-S). The portfolio also includes specialized solutions for hydropower plants (Stop-/Throttle Valves, Spherical Valves, Hollow-jet Valves), high-pressure applications (Cl 1500/2500), high temperature applications (up to 950°C), cryogenic/LNG applications (down to -196°C), hydrogen applications, nuclear power applications, FCC refining processes, and large diameter valves (up to DN4200). The company operates through subsidiary ADAMS Hydro Valves Inc. for hydropower and water applications. All products are manufactured in Germany (Herne) with a focus on custom-engineered solutions for critical industrial applications.

Partnerships

One partnership is on record.

• Siemens KraftwerksbaucoreStrategic or Co-development Partner · 1 January 2000Strategic partnership for development and construction of turbine safety valves for nuclear power plants. ADAMS developed 12 special turbine safety valves for the Olkiluoto nuclear power plant in Finland, which houses the world's most powerful steam turbines at 1,700 MW. The project involved complete new development of a double-valve construction measuring 2.80 meters in length. Siemens awarded ADAMS the Supplier Award for the quality of this technical cooperation.
