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:
butterfly check valve is used for drinking water pipelines and industrial piping system for environmental protection, water treatment, water supply, seawater utilization and drainage pipelines in high-rise buildings to prevent the reverse flow of media..
