H76H butterfly check valve is used in pure pipelines, industrial, environmental protection, water treatment, and high-rise building water supply and drainage pipelines to prevent the reverse flow of media. This check valve adopts a clamp type design, with a butterfly plate consisting of two semicircles and a spring forced reset. The sealing surface can be made of wear-resistant material or rubber lining deposited on the body, with a wide range of applications and reliable sealing.
