The NEXTG3N series from ARI represents a significant advancement in valve technology, with the all-new ZESA/GESA butterfly valves designed to optimize performance across various applications. This new generation of soft-sealing butterfly valves features three distinct disc designs: single shaft, curved, and HEXO honeycomb, each engineered to enhance flow efficiency and reduce turbulence.

One of the standout features of the NEXTG3N series is its optimized disc design, which minimizes friction and pressure losses, resulting in improved Kvs values. This enhancement not only facilitates smoother flow but also contributes to reduced noise and vibration within the system, creating a more pleasant operational environment. The shorter outlet section further aids in maintaining a streamlined flow, reducing the likelihood of dirt deposits. In addition, the innovative polygonal connection between the shaft and disc guarantees maximum reliability and torque transmission, eliminating any notching effect.

Durability and ease of maintenance are also key advantages of the NEXTG3N series. The valves are designed with replaceable components, allowing for straightforward servicing and extending the product's lifespan. The use of a variety of certified liner materials ensures compatibility with diverse applications and temperature ranges, making these valves suitable for industries such as HVAC, biogas and seawater applications.

Furthermore, the series includes optional special versions tailored for specific needs, such as an industrial version with a robust cast lever and metallic notched plate, and a cold temperature version designed for use in extreme conditions down to -20° C (-4° F).
