    Product Advantage of butterfly valve lug body

    The advantages of lug butterfly valve body

    compared to wafer butterfly valve:
    1. The lug butterfly valve body have the same structural length with the wafer butterfly valve,  so lug butterfly valve can be installed in a relatively compact space.

    2. Lug butterfly valves usually require the use of multiple bolts and nuts to clamp the valve body between the flanges of the pipe, so they are 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.
