Discover our product innovations for 2024

Our experts are continually working on new products and product expansions. Here we present you with this year’s highlights from the development department of ARI-Armaturen.


Our double offset butterfly valve for significantly optimised Kvs values. Now with TSO tight-shut-off end stops as a standard feature for a safe closed position even with bare shaft.


Our high-performance control valve for professional control – especially in critical applications. Now also available in heat-resistant carbon steel for applications up to +530 °C and with butt weld ends for high pressure applications up to 160 bar.


The first soft-sealing butterfly valve with three optimised disc designs for improved Kvs values as well as a less turbulent flow and therefore shorter outlet pipe lengths.


Our robust pilot operated pressure reducing valve with precise control – even with widely varying flow rates and inlet pressures. PFAS-free design as standard.


Our metallic sealing triple eccentric butterfly valve for the most demanding applications. Available soon in cryogenic version for temperature ranges from -196 °C.
