What is the purpose and structural characteristics of the swing check valve?

Swing check valve is suitable for nominal pressure PN1.0MPa~42.0MPa, CLASS150Lb~2500Lb; nominal diameter DN15mm~1200mm, NPS1/2″~48″; working temperature -196C~540C for various pipelines, used for Prevent the media from flowing backwards. By using different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, strong oxidizing medium and urea.
