ASTM Standard Carbon Steel Flange Check Valve DN150 For Chemical Industry
Carbon steel flange check valve description
Carbon steel flange check valve is also called one-way valve or non-return valve, its function is to prevent the medium in the pipeline from flowing back. The opening and closing parts are automatically opened or closed by the flow and force of the medium to prevent the valve from flowing back. Check valve belongs to the automatic valve category, which is mainly used in pipelines with one-way flow of medium, and only allows the medium to flow in one direction to prevent accidents.

Structural features of the check valve
1. Short structure length, its structure length is only 1/4~1/8 of the traditional flange check valve
2. Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve
3. The valve disc closes quickly and the water hammer pressure is small
4. It can be used in horizontal or vertical pipelines and is easy to install
5. The flow channel is unobstructed and the fluid resistance is small
6. Sensitive action and good sealing performance
7. The valve disc has a short stroke and a small closing impact force
8. The overall structure is simple and compact, and the shape is beautiful
9. Long service life and reliable performance
