The flanged butterfly valve boasts a highly efficient disc-shaped closing element, known as the butterfly plate, which effortlessly rotates 90° to provide seamless on/off control. Enhanced by its robust flanged connections, it stands out with a streamlined structure that ensures swift operation and unparalleled precision in flow regulation. This versatile valve is extensively adopted in low to medium-pressure pipelines spanning industries such as oil, chemical processing, water treatment, and power generation.
Advantage: When compared to traditional gate valves and globe valves, flanged butterfly valves are remarkably 30-50% lighter and more compact, making them the optimal choice for installations in space-limited piping systems.
Applications: Perfectly suited for use in ships, underground pipelines, and bustling industrial plants with tight configurations.
Technical Basis: The innovative disc design rotates a full 90° for seamless opening and closing, effectively negating the need for a rising stem mechanism.
Advantage: A swift 90° rotation (completed in just 1-2 seconds) ensures full valve operation, with the added benefit of partial opening for meticulous flow regulation, where softer seals significantly enhance modulation accuracy.
Vs. Competitors: In contrast, gate valves demand multiple turns for operation, and although ball valves offer speed, they lack the precision crucial for effective throttling.
Use Case: Ideal for systems demanding frequent operation or precise flow adjustments, such as cooling water loops.
Soft Seals (Rubber/PTFE): Achieves bubble-tight leakage (ensuring Zero Fugitive Emissions), making it perfect for applications involving water, gases, and mildly corrosive media.
Hard Seals (Metal/Alloy): Built to withstand extreme temperatures (up to 600°C) and pressures (PN40/ANSI 600#), ideal for steam and oil applications.
Innovation: The cutting-edge triple-offset design guarantees zero-friction sealing performance, significantly prolonging the service life by 3-5 timescompared to traditional designs.
Advantage: The fully open disc aligns perfectly with the flow, drastically reducing pressure drop to just one-tenth of that experienced by gate valves, thereby cutting down on pump energy consumption.
Data: Pressure loss is impressively low (<0.1 bar for water, DN200).
Ideal For: Suitable for high-flow systems, including municipal water networks and power plant cooling systems.
Maintenance: Replacement of the seat or seal is straightforward and can be performed without removing the valve itself (in certain advanced designs).
Cost Savings: Enjoy a 40% reduction in initial costs compared to traditional gate valves; Revolutionize your cost savings with installation expenses slashed by half! Enjoy the ease and efficiency of our flanged connection simplicity.
Case Study: Petrochemical plants report remarkable improvements and success. Benefit from a reduction in annual maintenance costs by a substantial 30%..
Actuation Options: Choose from manual (lever/gear), electric, pneumatic, or hydraulic for seamless operation.
Material Flexibility:
Body: Select from cast iron for cost-effectiveness, SS316L for corrosion resistance, or duplex steel for unmatched strength.
