A Double Eccentric Wafer Butterfly Valve is a high-performance valve designed for flow regulation and isolation in fluid systems. The term "double eccentric" refers to the unique design of the valve's disc and shaft, where both the shaft and the seat are offset from the centerline. This design reduces friction and wear on the sealing surface, ensuring a longer lifespan and more efficient operation. The double eccentric construction allows the valve to achieve a tight seal while minimizing the torque required to operate the valve, making it easier to control.
The wafer-style construction of the Double Eccentric Butterfly Valve makes it compact, lightweight, and easy to install between flanges, which is ideal for space-constrained applications. This valve type is commonly used in industries such as oil and gas, water treatment, HVAC, and chemical processing, where reliable and efficient flow control is critical. It provides excellent shutoff capabilities and can handle a wide range of fluid pressures and temperatures, making it suitable for diverse industrial applications.
Double Eccentric Wafer Butterfly Valve is trusted across various industries for its precision, durability, and reliability. Explore its wide-ranging applications below:
Used for regulating the flow of crude oil, natural gas, and refined products in pipelines and processing plants, providing efficient flow control and reliable sealing.
Employed in steam, feedwater, and cooling systems to regulate flow and maintain system efficiency in high-pressure environments.
Installed in water treatment and distribution systems to ensure precise flow regulation and reliable shutoff, helping maintain efficient water management.
Handles flow regulation in chemical production systems, providing a durable and efficient valve solution for both high and low-pressure environments.
Used in HVAC systems for regulating air or water flow, offering tight shutoff and ensuring the efficiency of heating and cooling systems.
Installed in marine and offshore platforms to control fluid flow in ballast water, fuel, and cooling systems, ensuring reliable operation in marine environments.
