Introduction of Swing Check Valve
Swing check valve, also known as one-way valve or non-return valve, is used to prevent the backflow of media in the pipeline. The opening and closing parts are opened or closed on the basis of medium flow and force. The valve that prevents the back-flow of medium is called the check valve. Check valve belongs to automatic valves. It is mainly used for pipes with unidirectional flow of media. To prevent accidents, medium is allowed to flow in only one direction.
The swing check valve is suitable for various pipelines with the nominal pressure PN0.6MPa~42.0MPa, Class150-2500, nominal diameter DN15~1200mm, NPS1/2~48, and working temperature 196~540℃, and it is used to prevent the back flow-of medium. By selecting different materials, it can be applied to many kinds of media, such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea.
