Check valve, also known as check valve or one-way valve, is a valve that automatically opens and closes under the action of the pressure difference between the front and back of the valve. Its function is to make the medium flow in only one direction, and prevent the medium from flowing back in the opposite direction. According to the different structure of the check valve, there are lift type, swing type and butterfly wafer type. The lift check valve is divided into horizontal and vertical. When installing the check valve, you should also pay attention to the flow direction of the medium.
