A check valve is also known as reflux valve, cut-off valve, counterbalance valve or non-return valve. As an automatic valve, it automatically opens or closes with the help of the force of media flow within the pipeline. Its application range varies in accordance with different materials.
The stainless steel check valve is usually applied in pipeline system to prevent medium from backflow, stop pump and driving motor from inversion and avoid the discharge of medium.
It can also be used on the pipeline which delivers supplies to auxiliary system with higher pressure than that of main system.
Once the valve is mounted on the pipeline, its opening or closing may be influenced by the instantly changed flow state. Meanwhile, the valve state has an impact on flow state.
