Introduction
Check valve, also known as check valve or check valve, its function is to ensure that the medium in the pipeline directional flow without backflow function. Check valves are automatic valves. Pressure 1.6~25MPa, suitable medium for water, oil, low temperature medium, etc.

Working Principle
Usually, the pressure causes the disc of the valve to open and flow from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side, the disc automatically closes the channel under the action of the fluid pressure, spring elasticity and its own gravity, preventing the flow from countercurrent.
