ARI-STEVI Pro 470/471-PN40-bwe

The ARI-STEVI Pro 470/471 PN40 control valve from Ari-Armaturen with butt weld ends is designed for high-integrity installations where strength and leak-tight performance are essential. Its straight-through design and shaft guided plug provide precise and stable control, even in the most demanding operating conditions. The butt weld connection ensures a permanent, secure installation, making this variant particularly suitable for high-pressure and high-temperature systems in power generation, chemical processing, and heavy industrial environments. Capable of handling media such as steam, thermal oil, hot water, gases and refrigerants, the valve operates reliably across temperatures ranging from -60°C to +450°C. This configuration is ideal for applications where minimising leakage risk and maximising system integrity are critical.
