GEMÜ D450

The GEMÜ D450 plastic bare shaft butterfly valve provides UV resistant flow isolation for industrial liquid applications. The GEMÜ D450 accommodates nominal sizes from DN 50 to DN 300, regulates operating pressures up to 10 bar, and withstands media temperatures ranging from 0°C to 90°C. Key Performance Capabilities: Corrosive Media Resistance: The GEMÜ D450 uses a glass-filled polypropylene (PP-GF) body alongside PVC-U, PVC-C, or PP-H disc options, preventing chemical degradation to extend component lifespan within corrosive liquid handling systems. Actuation Efficiency: The GEMÜ D450 incorporates a disc design engineered for low torque, preventing actuator motor fatigue and ensuring uninterrupted automated isolation during high-cycle industrial operations. Environmental Durability: The GEMÜ D450 features UV resistant external construction, preventing material embrittlement during outdoor pipeline installations to eliminate unplanned maintenance downtime caused by continuous environmental exposure. Safety & Compliance: Global Flange Compatibility: The GEMÜ D450 wafer body aligns with ISO/DIN, ANSI/ASTM, British Standard, and JIS standard connections, ensuring plant engineers can integrate one universal valve model across diverse international piping frameworks. Guaranteed Sealing: The GEMÜ D450 deploys EPDM or FPM seat liners, providing strict fluid containment up to 10 bar for DN 50 to DN 200 pipeline sizes to eliminate leakage and prevent media cross-contamination. Note: The maximum operational media temperature range depends strictly on the specific disc material selected for the GEMÜ D450 configuration.
