What is a check valve?
A check valve refers to a valve that automatically opens and closes the valve flap by means of the flow of the medium itself, and is used to prevent the medium from flowing backward.
★ Lifting type: good sealing performance, simple structure, and large flow resistance.
★ Swing type: poor sealing performance, complex structure, small flow resistance, mostly used in pipelines with a large caliber.
★ The main use: A check valve is suitable for pipelines that have the requirement to prevent media backflow. Check valves are generally suitable for cleaning media and should not be used for media containing solid particles and with high viscosity.
