Product Introduction

Double flange butterfly valve is a type of butterfly valve that has flanges on both ends of the valve body. These flanges enable easy installation and removal of the valve from the pipeline, making it a popular choice for various applications. Double flange butterfly valves are also known for their high flow capacity and excellent sealing ability.

The valve consists of a disc that rotates on an axis to control the flow of fluid through the pipeline. When the disc is in a closed position, the sealing surface of the disc comes in contact with the sealing surface of the valve body, creating a tight seal that prevents any leakage of fluid.

Double flange butterfly valves are commonly used in industries such as water treatment, HVAC, chemical, and food processing. They are available in a wide range of sizes, materials, and designs to suit different applications and requirements.
