GEMÜ D487

The GEMÜ D487 manual metal butterfly valve provides reliable flow isolation for industrial applications and water treatment. The GEMÜ D487 accommodates nominal sizes from DN 25 to DN 1600, regulates operating pressures up to 16 bar, and withstands media temperatures ranging from -60°C to 210°C. Key Performance Capabilities: Customised Media Compatibility: The GEMÜ D487 offers extensive disc material options including CF8M, Super Duplex and Hastelloy, combined with EPDM, FKM, or PTFE liners, preventing chemical corrosion to eliminate unplanned component replacement downtime. Manual Actuation Control: The GEMÜ D487 integrates an aluminium latching hand lever or gearbox hand wheel operator, delivering mechanical flow regulation to eliminate process downtime during manual pipeline interventions. Guaranteed Flow Isolation: The GEMÜ D487 achieves EN 12266-1/P12 leak rate A bubble tight sealing, preventing fluid loss and eliminating unplanned maintenance downtime caused by cross-contamination within critical industrial pipelines. Safety & Compliance: Explosive Environment Security: The GEMÜ D487 secures ATEX 2014/34/EU compliance for fluids of group 1 and 2, preventing ignition risks to guarantee facility safety and continuous operation within volatile industrial zones. Water & Gas Compliance: The GEMÜ D487 achieves DVGW, WRAS and ACS certifications (depending on the specific seat material selected), ensuring plant engineers can standardise one manual valve across strict potable water and gas distribution networks. Note: The maximum operational media temperature, pressure and vacuum resistance depend strictly on the specific seat (liner) material and liner fixing selected for the GEMÜ D487 configuration.
