ARI-Armaturen Albert Richter GmbH& Co. KG
About
ARI-Armaturen Albert Richter GmbH & Co. KG is a family-owned, medium-sized German industrial valve manufacturer founded in 1950 and based in Schloss Holte-Stukenbrock. The company produces over 20,000 valve products in more than 200,000 variants, organized into six categories: control valves, isolation valves, safety valves, steam trapping, actuators, and system solutions. ARI's butterfly valve portfolio includes the ZESA and GESA soft-sealing lines — recently upgraded with the nextg3n platform featuring three optimized disc geometries for improved Kvs values and reduced turbulence — and the ZEDOX HEXO double-offset series with TSO tight-shut-off end stops standard. The ZETRIX line targets fugitive emissions compliance to TA-Luft and DIN EN ISO 15848-1 standards, serving chemical and petrochemical applications. The PREMIO actuator series provides pneumatic and electric automation for valve operation, configurable via the dedicated myPREMIO app. ARI valves handle a broad range of media including steam, heat transfer oil, ammonia, hot and cold water, hydrogen, and oxygen across nine market sectors: general industry, HVAC, shipbuilding, oil and gas, chemical, pharmaceutical and biotechnology, food and beverage, energy, and medium-pressure applications. The company operates 16 international subsidiaries and offers digital tools including the myValve sizing application, ARI-ID digital nameplate, and myARI service portal.
Key Products
Regulating valves for modulating flow, pressure, and temperature of liquid and gaseous media in industrial process systems, available in numerous body materials and trim configurations.
Soft-sealing butterfly valves for tight shut-off of process media in piping systems, including the ZESA and GESA series for general and demanding isolation applications.
High-performance double-offset butterfly valves providing reliable sealing and low operating torque for critical isolation applications in industrial and HVAC systems.
Overpressure protection valves that automatically open to relieve excess pressure in vessels, piping, and process equipment, preventing equipment damage and safety hazards.
Condensate management devices that remove liquid condensate from steam systems while preventing steam loss, maintaining heat transfer efficiency and system performance.
Specialized valve line engineered for emissions compliance and demanding industrial applications requiring high sealing integrity.
Pneumatic and electric actuators for automated valve operation, enabling remote and programmable control of butterfly, globe, and other valve types in process automation systems.
Custom-engineered valve assemblies and integrated system packages combining multiple ARI products into pre-assembled, tested units for specific project requirements.
On-site and diagnostic testing services for steam trap performance assessment, identifying failed traps and recommending replacements to optimize steam system efficiency.
