GEMÜ R470

The GEMÜ R470 Tugela double eccentric bare shaft butterfly valve delivers bubble tight flow isolation for high performance industrial pipelines. The GEMÜ R470 accommodates nominal sizes from DN 50 to DN 600, manages operating pressures up to 40 bar, and withstands media temperatures from -40°C to 230°C. Key Performance Capabilities: Reduced Mechanical Wear: The GEMÜ R470 uses a double eccentric construction to separate the disc directly from the seat during operation, drastically reducing mechanical friction to prevent premature component failure and lower long term replacement costs. Leakage Prevention: The GEMÜ R470 integrates a continuous shaft with a temperature resistant graphite bearing and readjustable PTFE gland packing, minimising fluid leakage even at low pressures to eliminate unplanned maintenance downtime. Guaranteed Flow Isolation: The GEMÜ R470 achieves EN 12266-1/P12 leak rate A bubble-tight sealing, preventing costly media loss and eliminating cross contamination risks within critical processing lines. Safety & Compliance: Explosive Environment Security: The GEMÜ R470 features an antistatic fixture and secures ATEX certification, preventing ignition risks to guarantee facility safety and continuous operation within volatile industrial zones. Emissions & Food Grade Compliance: The GEMÜ R470 achieves TA Luft and FDA conformities, ensuring plant engineers can standardise one high performance valve across strict emission-controlled environments and sanitary food processing lines. Note: The maximum operational media temperature range depends strictly on the specific liner, disc material and liner fixing selected for the GEMÜ R470 configuration.
