Swing check valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and the swing check valve is a kind of automatic valve.

Structural Characteristics of Swing Check Valve:

1. Prevent liquid backflow phenomenon, protect pump equipment, etc.;

2. Since it is a cantilever check valve, it has less resistance to the fluid;

3. The valve body can be disassembled from the piping, and the bonnet can be opened for internal inspection and maintenance.

Swing check valve adopts a built-in rocker arm swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring in the middle flange, there is no leakage point, to prevent the possibility of valve leakage. The applicable medium of the swing check valve is: water, oil, steam, acidic medium, etc. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, pharmaceuticals, and electric power.
