Brief introduction of swing check valve:

Swing check valve ,also known as one-way valve or non-return valve, is used to prevent the back-flow of the mediums in the pipelines. The valve that opens and closes driven by the flow force of the medium to prevent the medium from flowing back is called check valve. The check valve belongs to the automatic valve category, which is mainly used on the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. This type of check valve should generally be installed horizontally in the pipeline.

Characteristics of swing check valve:

1. short structure length, small in size, light in weight.
2. Rapid closing, small water hammer pressure.
3. Its easy to be installed horizontally or vertically.
4. Smooth flow channel and small flow resistance.
5. the valve disc travel is short, and the closing impact force is small.

Applications of swing check valve:

This swing check valve is widely used in petroleum, chemical, pharmacy, electric power, and other industries, and can be used to open and close the pipeline systems of steam, water, and oils.
