Swing check valve introduction:
Swing check valves are automatically opened and closed by the force generated by the flow of the medium itself in the pipeline and belong to an automatic valve.
Check valve for pipeline system, and its main role is to prevent the backflow of media, to prevent the pump and its drive motor reversal, as well as the release of media in the container.
Check valve products can also be used to supply the auxiliary system in which the pressure may rise above the main system pressure.

8.The valve flap closed fast, water hammer pressure is small.
9.Horizontal pipe or vertical pipe can be used, convenient installation.
10.The flow channel is unobstructed, the fluid resistance is small.
11.Sensitive action, good sealing performance.
12.Short stroke, close the impact force is small.
13.The overall structure is simple and compact, beautiful appearance.
14.Long service life, reliable performance.
