check valve
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 features a brand-new structure, small volume, light weight,small fluid resisteance, reliable seal, stable open-close, long duration, better energy-saving effect.
Suitable for the pipeline related to water supply and drainage, fire-fighting, warming etc. Systems 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 form the silencing effect.
