The liner materials used in the construction of DK butterfly valve are either Elastomer
or TEFLON Õ . Wafer construction provides maximum strength under conditions of
pipeline strain. DK performs three basic functions of stopping flows, controlling flow
and regulating flows and pressure with several advantage functions such as
