ARI-ZEDOX 121

The ARI-ZEDOX 121 butterfly valve is a high-performance double offset valve designed for reliable isolation in demanding industrial and process applications. Featuring a butt weld end connection, this PN25 valve provides a secure, permanent installation, making it ideal for systems where strength, integrity and leak prevention are critical. The double offset design reduces friction between sealing surfaces during operation, minimising wear and extending the valve’s service life. This ensures consistent sealing performance and dependable operation across a wide range of challenging environments. Designed for use in industries such as oil and gas, petrochemical processing, power generation, district heating and heavy industrial manufacturing, the ARI-ZEDOX 121 is suitable for a broad spectrum of media including steam, thermal oil, gases, refrigerants, acids, alkalis and de-ionised water. With an operating temperature range from -40°C to +260°C and sizes available from DN200 to DN1600, this valve is particularly well suited to large-scale systems requiring robust and reliable isolation. The butt weld connection ensures a high-integrity installation, making the ARI-ZEDOX 121 an ideal solution for critical applications where safety and long-term performance are essential.
