The 31000 Series is a PFA lined control valve with an eccentric rotary plug, which provides tight shut off, low dynamic forces, and excellent control. This valve is an excellent solution for hydrofluoric and sulfuric acid applications.	The 34003 Series Ultra-Max is low noise and anti-cavitation rotary control valve for gas and liquid applications. Ultra-Max features a full trunnion mounted ball with noise attenuation trim. A wide range of available materials allows Ultra-Max to be customized to suit the application needs. Typically applied in fuel gas control and process applications requiring high capacity/high turndown, non-clogging operation.	As the original eccentric plug rotary valve, the Camflex combines top performance and features with an extremely economical design. The Camflex offers enormous versatility and broad application, and remains the most widely used eccentric plug control valve in the world. Now supplied with the EF seal solution to reduce fugitive emissions.
