Butterfly check valves are used in pure pipelines and industrial, environmental protection, water treatment, and high-rise building water supply and drainage pipelines to prevent reverse flow of media.
Product features: Check valves are installed in pipeline systems, primarily to prevent backflow of media. They are automatic valves that rely on media pressure to open and close. In the past, the commonly used types in China were the H44 flanged connection swing check valve and the H41 flanged connection lift check valve. These traditional check valves are bulky, have high fluid resistance, generate high water hammer pressure when closing, are difficult to install and maintain, and have a short service life.
