The innovative Double Offset Flanged Butterfly Valve with PTFE Lining from Tianjin ET Valve Co., Ltd stands out with its unique disc-shaped closing element, the butterfly plate, expertly engineered to rotate a full 90° for swift and efficient on/off control. Designed with robust flanged connections, it boasts a meticulously crafted compact structure, ensuring quick operation and offering precise flow regulation, making it an indispensable component for low to medium-pressure pipelines across diverse sectors such as oil, chemical processing, water treatment, and power industries.
Advantage: In comparison to the bulkier gate valves and globe valves, our flanged butterfly valves are a remarkable 30-50% lighter and more compact, making them exquisitely suited for installation in space-restricted piping systems where efficiency is paramount.
Applications: Perfect for ships, underground pipelines, and densely packed industrial plants where space is at a premium.
Technical Basis: Its design allows the disc to rotate a full 90° for seamless full open/close operations, ingeniously eliminating the necessity for a rising stem.
Advantage: With its instant 90° rotation (achieved in just 1-2 seconds) for full operation, it allows partial opening capabilities for meticulous flow regulation, where softer seals deliver enhanced modulation accuracy.
Vs. Competitors: Unlike gate valves that demand multiple turns, and ball valves that may lack precision for throttling, our product excels.
Use Case: Ideally suited for systems demanding frequent operation or precise flow adjustments, such as cooling water loops.
Soft Seals (Rubber/PTFE): Deliver exceptional bubble-tight leakage protection (Zero Fugitive Emissions), making them ideal for water, gases, and mildly corrosive media.
Hard Seals (Metal/Alloy): Designed to withstand extreme temperatures (up to 600°C) and pressures (up to PN40/ANSI 600#), making them perfect for steam and oil applications.
Innovation: The advanced triple-offset design guarantees zero-friction sealing, significantly extending the service life by 3-5 times.
Advantage: When fully open, the disc aligns perfectly with the flow, dramatically reducing pressure drop to a mere 1/10th of that found in gate valves, substantially cutting down on pump energy costs.
Data: Experience pressure loss of less than 0.1 bar (for water, DN200), showcasing its efficiency.
Ideal For: High-flow systems such as municipal water services and power plant cooling, where efficiency is key.
Maintenance: Designed for convenient seat/seal replacement without necessitating the removal of the valve (in specific designs).
Cost Savings: Enjoy an impressive 40% reduction in upfront costs, enhancing economic efficiency. Experience the superior advantages of our innovative valve system compared to traditional gate valves; Enjoy a remarkable 50% reduction in installation costs, making it a financially savvy choice for your projects. Thanks to the flanged connection simplicity, installation has never been easier.
Case Study: In recent studies, petrochemical plants report tremendous performance improvements using our valves. Benefit from an impressive 30% reduction in annual maintenance costs, effectively minimizing operational expenses..
Actuation Options: Choose from a variety of actuation options: Manual (lever/gear), electric, pneumatic, or hydraulic, to suit any application.
Material Flexibility:
Body: Carefully crafted with diverse materials such as cost-effective cast iron, corrosion-resistant SS316L, or high-strength duplex steel to meet all your needs.
Seals: Select from EPDM for acid/alkali resistance, NBR for oil resistance, or PTFE for chemical-proof sealing solutions.
Industry Compliance: Achieves comprehensive industry standards, ranging from FDA-grade compliance for food and pharmaceutical applications to robust ASME III standards suitable for nuclear applications.
