The soft-seated butterfly valves ZESA/GESA® NEXTG3N from ARI-Armaturen impress with their optimized flow rate and increased KVS values, which come into play in every nominal size thanks to the innovative disc design. The single shaft design is used for DN 25-50, the curved design for DN 65-200 and the HEXO honeycomb design for DN 250-600.
 The shaft-disc connection is designed as a positive-locking polygon for optimum torque transmission. The standard blow-out preventer in accordance with DIN EN 593 and API 609 in the form of a shaft lock washer is firmly bolted to the head flange. The utility model-protected HEXO honeycomb design reduces turbulence as well as friction and pressure losses, thus optimizing the KVS values. The weight advantage of the new disk geometry also facilitates handling in the system.
 These advantages make the ZESA/GESA® NEXTG3N ideal for a wide range of applications: from heating, air conditioning and chilled water systems in building services to industrial systems such as compressed air or seawater systems.
