DN800 DI Single Flange Type Wafer Butterfly Valve

The single flange butterfly valve combines the advantages of the wafer butterfly valve and the double flange butterfly valve: the structural length is the same as the wafer butterfly valve, so it is shorter than the double flange structure, lighter in weight and lower in cost. The installation stability is comparable to that of a double-flange butterfly valve, so the stability is much stronger than that of a wafer structure.

    Product Advantage

    Single flange butterfly valve refers to the structure of the valve body, which consists of a flange longitudinally surrounding the center of the valve body and installed by connecting to a flange on the pipeline.

    The butterfly plate can adjust the flow of fluid by rotating 90 degrees or less, thereby opening, closing or regulating the fluid in the pipeline.

    Its features include simple structure, quick opening and closing, light operation, and good sealing performance.

    This type of butterfly valve is commonly used to control fluids in industrial pipelines, especially for large-diameter pipelines (DN300 or greater) and low-pressure systems. They are often used in air ducts, chemical industry, water supply and drainage systems, cooling water systems and several other uses.

    Single flange butterfly valves are designed to be easy to install and maintain and are a common choice in many industrial piping systems.

    About Products:

    1. What is a single flange butterfly valve?
    A single flange butterfly valve is a type of valve used to control the flow of a fluid in a piping system. It consists of a disc that rotates around a central axis which allows for quick and efficient flow control.

    2. What are the applications of a single flange butterfly valve?
    Single flange butterfly valves are commonly used in various industries such as water treatment, sewage treatment, chemical processing, and power generation. They are also used in HVAC systems and in shipbuilding.

    3. What are the advantages of a single flange butterfly valve?
    Some of the advantages of a single flange butterfly valve include its lightweight and compact design, low pressure drop, ease of installation, and low maintenance requirements.

    4. What is the temperature range for a single flange butterfly valve?

    The temperature range for a single flange butterfly valve depends on the material of construction. Generally, they can handle temperatures ranging from -20°C to 120°C, but higher temperature materials are available for more extreme applications.

    5. Can a single flange butterfly valve be used for both liquid and gas applications?

    Yes, single flange butterfly valves can be used for both liquid and gas applications, making them versatile for a wide range of industrial processes.

    6. Are single flange butterfly valves suitable for use in potable water systems?

    Yes, single flange butterfly valves can be used in potable water systems as long as they are made from materials that comply with the relevant drinking water regulations and standards, so we get the WRAS certificates.
