Explore our comprehensive product offerings at Tianjin ET Valve Co., Ltd by visiting https://et-valve.en.made-in-china.com/product-list-1.html. Discover the ET Control Valve with Multi-Disc Design for Optimal Flow Regulation and more, all tailored to meet your specific needs with precision and excellence.
OEM DN50~DN2000 Pn6~Pn40 Manual / Electric / Pneumatic Actuated Flanged Butterfly Valve
The flanged butterfly valve boasts a sophisticated design with a disc-shaped closing element (butterfly plate) that effortlessly rotates 90° to control flow, providing seamless on/off functionality. Equipped with robust flanged connections, it stands out due to its compact structure, rapid operation speed, and exceptional precision in flow regulation, making it a preferred choice across low to medium-pressure pipelines in the oil, chemical, water treatment, and power sectors.
Advantage: In comparison to traditional gate valves and globe valves, flanged butterfly valves are significantly 30-50% lighter and more compact, ensuring they are the ideal solution for systems where space is at a premium.
Applications: Perfectly suited for ships, underground pipelines, and densely packed industrial facilities.
Technical Basis: The disc achieves 90° rotation for complete open/close, designed to eliminate the need for a rising stem mechanism.
Advantage: Experience instantaneous 90° rotation (1-2 seconds) for full operational readiness, offering partial opening options to ensure meticulous flow regulation—softer seals enhance modulation capability.
Vs. Competitors: While gate valves require numerous turns, and ball valves offer speed but lack precision in throttling, flanged butterfly valves deliver both speed and control.
Use Case: Designed for systems necessitating frequent operations or precise flow adjustments, such as cooling water loops.
Soft Seals (Rubber/PTFE): Achieve bubble-tight leakage (Zero Fugitive Emissions), making it ideal for handling water, gases, and mildly corrosive materials.
Hard Seals (Metal/Alloy): Engineered to withstand elevated temperatures (≤600°C) and high pressures (PN40/ANSI 600#), these valves are perfect for steam and oil applications.
Innovation: The triple-offset design guarantees zero-friction sealing, significantly extending the service lifespan 3-5 times longer.
Advantage: When fully open, the disc aligns perfectly with the flow, dramatically reducing pressure drops to a mere 1/10th of what gate valves experience, thereby slashing pump energy expenditures.
Data: Pressure drop is minimal at <0.1 bar (specifically for water and DN200 applications).
Ideal For: Optimal for high-flow systems such as municipal water services and power plant cooling operations.
Maintenance: Simplifies seat/seal replacement without necessitating valve removal (applicable in certain designs).
Significant Cost Savings: Enjoy a remarkable 40% reduction in upfront costs compared to traditional gate valves; Experience up to 50% savings on installation thanks to the flanged connection's straightforward simplicity.
Real-World Case Study: Leading petrochemical plants showcase a commendable 30% decrease in annual maintenance expenseswith our innovative solutions.
Diverse Actuation Options: Choose from manual (lever/gear), electric, pneumatic, or hydraulic options to suit your needs.
Robust Material Flexibility:
Valve Body Choices: Opt for cast iron for cost-effectiveness, SS316L for superior corrosion resistance, or duplex steel for exceptional high strength.
Advanced Seals: EPDM for excellent acid/alkali resistance, NBR for outstanding oil resistance, and PTFE for superior chemical-proof properties.
Stringent Industry Compliance: Spanning from FDA-grade standards for food and pharmaceutical applications to ASME III standards for the nuclear industryensuring unwavering reliability and safety.
