The flanged butterfly valve harnesses a disc-shaped closing element, known as the butterfly plate, which elegantly pivots a full 90 degrees for flawless on/off control. With its robust flanged connections, this valve is engineered to deliver a compact structure, swift operation, and precision in flow regulation, making it an indispensable choice for low to medium-pressure pipelines across the oil, chemical, water treatment, and power sectors.
Advantage: When compared to gate and globe valves, flanged butterfly valves are 30-50% lighter and more compact, rendering them perfect for space-limited piping systems.
Applications: This valve shines in ships, underground pipelines, and cramped industrial facilities.
Technical Basis: The disc rotates 90° for seamless full open/close action, eliminating the need for a cumbersome rising stem.
Advantage: Experience instant 90° rotation (1-2 seconds) for full operation, while the option for partial opening ensures meticulous flow calibration (softer seals enhance modulation precision).
Vs. Competitors: Unlike gate valves that require laborious multiple turns, and ball valves that offer speed but lack precise throttling, our solution excels.
Use Case: Ideal for systems demanding frequent operation or precise flow adjustments, such as cooling water loops.
Soft Seals (Rubber/PTFE): Provide impeccable bubble-tight leakage (Zero Fugitive Emissions), perfectly suited for handling water, gases, and mildly corrosive media.
Hard Seals (Metal/Alloy): Endure extreme temperatures (≤600°C) and pressure (PN40/ANSI 600#), making them apt for steam and oil applications.
Innovation: The triple-offset design guarantees frictionless sealing, thus extending the service life by 3-5 times.
Advantage: When fully opened, the disc aligns with the flow, minimizing pressure drop to just 1/10th of what gate valves experience, thereby significantly reducing pump energy expenses.
Data: Pressure loss is kept under 0.1 bar (for water, DN200).
Ideal For: Perfect for high-flow systems, including municipal water services and power plant cooling operations.
Maintenance: Allows for seat/seal replacement without removing the valve (in certain designs).
Cost Savings: Boasts a 40% lower upfront cost compared to gate valves; offering a budget-friendly yet effective solution. Enjoy up to 50% savings on installation costs, making our valves an incredibly economical choice. Thanks to the simplicity of the flanged connection, installation has never been easier.
Case Study: Delve into insights from Petrochemical plants, highlighting our valve's excellent performance. Experience a remarkable 30% reduction in annual maintenance costs, ensuring long-term savings..
Explore an array of Actuation Options: Choose from manual (lever/gear), electric, pneumatic, or hydraulic to suit your specific needs.
Material Flexibility:
Body: Options include cost-effective cast iron, corrosion-resistant SS316L, or high-strength duplex steel.
Seals: Select from EPDM for acid/alkali resistance, NBR for oil resistance, or PTFE for chemical-proof assurance.
Industry Compliance: Ensuring adherence to standards from FDA-grade (ideal for food and pharmaceuticals) to ASME III (perfect for nuclear applications).
