  • Optimized geometry of valve assembly enables efficient throttling
  • Reliable shutdown and smooth operation

Product Description

Double eccentric butterfly valve, as the name suggests, feature a disc that is offset from the centerline both axially and radially. This design sets it apart from concentric and single eccentric valves. In a double eccentric valve, the axis of rotation of the disc is not only displaced from the pipe’s centerline but also misaligned with the seat, creating two off-center positions. This unique configuration enables a cam action during closure, ensuring minimal wear on the sealing surfaces and resulting in improved sealing effectiveness and lower torque requirements.Valve manufacturers in china represent a pinnacle of innovation in fluid control technology, offering advanced features, superior performance, and versatile applications across various industries.

Key Features Of Double Eccentric Butterfly Valves China

Double Eccentric Design: The unique double eccentric design of these butterfly valves involves two offsets – one offset from the centerline of the disc and the other from the shaft axis.

High-Performance Materials: Double eccentric butterfly valves from China are constructed using high-quality materials such as stainless steel, carbon steel, and special alloys to withstand corrosive environments, abrasive media, and extreme operating conditions.

Leak-Free Operation: With advanced sealing technologies including metal-to-metal or composite seals, double eccentric flanged butterfly valve ensure leak-free operation, preventing fugitive emissions and promoting environmental compliance.

Applications of Double Eccentric Butterfly Valves China

1. Petrochemicals and Chemical Processing: To regulate the flow of corrosive chemicals and high-pressure fluids.
2. Water Treatment and Supply: For controlling water flow, preventing backflow, and managing pressure fluctuations in distribution networks.
3. Power Generation: In steam lines, cooling systems, and fuel control circuits in thermal power plants and nuclear facilities.
4. HVAC Systems: For air conditioning units and heating systems, regulating airflow and maintaining system pressures.
5. Municipal Infrastructure: For sewage treatment plants and pipelines for waste management and flood control.
6. Food and Beverage Industry: Where hygienic and contamination-free operations are critical, they are often used due to their easy cleaning and maintenance features.
