GEMÜ 411

The GEMÜ 411 manual metal butterfly valve provides secure flow isolation for industrial process applications. The GEMÜ 411 accommodates nominal sizes from DN 15 to DN 50, regulates operating pressures up to 10 bar and withstands media temperatures ranging from -20°C to 160°C. Key Performance Capabilities: Customised Media Resistance: The GEMÜ 411 uses a 1.4408 stainless steel or CW614N/CW617N brass valve body, preventing chemical corrosion to lower long term component replacement costs within demanding fluid handling systems. Secure Mechanical Actuation: The GEMÜ 411 integrates a glass-fiber reinforced plastic hand lever featuring a built-in locking device, securing mechanical flow regulation at specific degree intervals to prevent accidental operation and eliminate unplanned process downtime. Targeted Sealing Integrity: The GEMÜ 411 offers EPDM, FKM and Silicone liner options, ensuring precise chemical compatibility to prevent fluid leaks and maintain continuous production line operation. Safety & Compliance: Explosive Environment Security: The GEMÜ 411 secures ATEX compliance, preventing ignition risks to guarantee facility safety and continuous operation within volatile industrial zones. Sanitary Process Compliance: The GEMÜ 411 achieves FDA conformity, ensuring plant engineers can standardise one manual metal valve across strict food grade and sanitary processing lines. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific liner and body material selected for the GEMÜ 411 configuration.
