What is swing check valve?

Swing check valve is a valve that can control the direction of the pipeline water flow. It is usually installed on the pipeline to prevent water flow back. Swing check valve uses the ball, cone, and other structures. It is automatically close or open according to the flow of the medium, which can adapt to different environments and media. When the fluid in the pipeline flows in the direction of the outlet, the valve is closed, on the contrary, when the fluid in the pipeline flows in the direction of the inlet, the valve is opened to make the fluid through the pipeline, to prevent backflow.

Advantages of swing check valve

1. Convenient operation

Swing check valve does not require external energy and control. It can be operated automatically on the pipeline without manual operation and convenient to use.

2. Automatic start function

When there is a fluid in the pipeline, the valve will be automatically started without manual intervention, and the response is rapid.

3. Long service life

Swing check valve does not need electric, manual, or other external energy. Its structure is simple and have no wearing parts, which has long service life.

4. Strong resistance to humidity and corrosion

The material of Swing check valve is excellent, it is not easy to be damp, rust or corrosion, and the material is wide applicability.

5. Prevent pipeline water flow back

Swing check valve can effectively prevent the pipeline fluid flow back, to ensure the production safety and stable operation of the pipeline

6. Wide range of application

Swing check valve is suitable for a variety of media and environment, such as urban water drainage, industrial water treatment, marine engineering, etc., which have a wide range of application prospects.
