    Product Advantage of butterfly valve lug body

    The advantages of lug butterfly valve body

    1. The lug butterfly valve body has the same length as the wafer butterfly valve. So, it can be installed in a compact space.

    2. Lug butterfly valves usually need multiple bolts and nuts. They clamp the valve body between the pipe flanges. This makes them more stable during installation and maintenance. But it will also increase installation time and bolt costs.

    3. Lug butterfly valves can be used at the end of pipes because the threads in the lugs can be directly fixed to the bolts.

    4.  A Hard back seat provides complete isolation of the medium from the valve body.

    5. Top Flange Standard ISO 5211.

    6. Lug Butterfly Valves body are designed by API609 and tested to API598.

    7. Anti-corrosion paint on the lug butterfly valve body can greatly extend its life. It will reduce maintenance and replacement needs. Many anti-corrosion paints resist chemicals like acids, alkalis, and salts. They suit harsh conditions, such as chemical plants and marine environments.

    About Products:

    1. What is a single flange butterfly valve body?
    A single flange butterfly valve body is a main component of the single flanged 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. As its FTF is the same with wafer butterfly valve.

    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.
