Performance Feature:
Check valves are used in pipeline systems. The main functions are to prevent backflow of the medium, to prevent the pump and its drive motor from reversing, and to release the medium in the container. The check valve can also be used to replenish the auxiliary system where the pressure may rise above the pressure of the main system. The check valve can be applied to pipelines of various media according to different materials. The check valve is installed on the pipeline, that is, it becomes one of the fluid components of this complete pipeline. The valve flap opening and closing process is affected by the transient flow state of the system，also it is in an effect on the fluid flow state.

Application:
With different materials, butterfly check valves can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
