Small resistance slow-close butteryfly check valve Characteristic use

        This valve is a safety device mounted in the pipeline or pump outlet to prevent the pump from inversed running due to the differential water hammer's shock in the pipeline when the pump stops. And it features by the brand-new structure, small fluid resistance, reliable seal, stable open-close, long duration, better energy-saving effect. Suitable for the pipeline related to the systems of water supply and drainage, fire-fighting, warming etc. or the pump outlet to prevent both pump and pipeline from being damaged due to the water hammer produced when the medium flows back and from the silencing effect.
