Swing check valve also known as one-way valve or check valve, its role is to prevent the medium flow back in the pipeline. The opening and closing parts open or close automatically by the medium flow and force to prevent the reverse flow of medium is called check valve. Check valve is an automatic valve, which is mainly used in the pipeline with one-way flow of medium. It only allows the medium to flow in one direction to prevent accidents. This kind of valve should be installed horizontally in the pipeline;

Swing check valve is suitable for various pipelines with nominal pressure of PN1.0MPa ~ 42.0mpa, class150-2500, nominal diameter of DN 15 ~ 1200mm, nps1 / 2 ~ 48, and working temperature of – 196 ~ 540 ℃ to prevent medium backflow. By selecting different materials (WCB, CF8 (m), CF3 (m), 1gr5mo, 15crmo1v, it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media. It is mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.
