【Product Features】

Swing-type steel check valve is automatically opened and closed in the pipeline and the flow of media generated by the force, is an automatic valve. Check valve for piping system, its main role is to prevent the media back to prevent the pump and its drive motor reversal, as well as the release of the container medium. The check sanitary valve may also be used on a line in which supplemental pressure which is supplied to an auxiliary system and the pressure may rise above the main system pressure.

Sanitary check valves are used for pure pipe and industrial, environmental protection, water treatment, high-rise building to the drainage pipe, to prevent the reverse flow of media purposes.
