Swing check valve is also called one-way valve or check valve, its function is to prevent the medium in the pipeline from flowing back. The valve whose opening and closing parts are opened or closed by the flow and force of the medium to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline.

Product features：

The swing check valve with a swing structure. All the opening and closing parts of the valve are inside the body of the valve . Except the sealing gasket and sealing ring at the middle of flange, There is without leakage point, so prevent the possibility leakage of the valve . The swing arm of the swing check valve adopts a spherical connection structure at the connection between the arm and the valve disc, so that the valve disc can has a certain degree of freedom within the range of 360 degrees, and there has an appropriate trace position compensation.The swing check valve suitable for clean medium,but not suitable for medium containing solid particles and high viscosity.

Advantage:

1. Selection of the materials are exquisite ,according to the domestic and foreign standards, and with high quality of materials.

2. The sealing of the swing check valve is advanced and reasonable. The sealing surface of the valve disc and valve seat is made of alloy steel or STL .,etc hard alloy surfacing surface, which has good resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.

3. Not only the valve body can be removed from the piping, but also the bonnet can be opened for internal inspection and maintenance.

4. With Various piping flange standards and flange sealing types can meet different engineering needs and user requirements.

5. The valve body can with complete variety of materials, and the gasket can be reasonably selected according to real working exquisite or user requirements, and can be suitable for various pressure, temperature and medium working conditions.
