Youfumi Horizontal lift check valve is designed to prevent reverse flow of the medium. It operates automatically—opening under forward flow pressure and closing when backflow occurs—using the force of the flow and the disc’s own weight. Suitable for unidirectional flow systems, it effectively prevents backflow accidents. With a simple structure and minimal flow resistance, this valve ensures reliable performance and easy integration into various pipelines.
