Process Check valve silent Hydrostop

The Silent Hydrostop non-return valve is used in water distribution systems to prevent the backflow of polluted water. In addition to this application, Silent Hydrostop can also be used as a non-return valve for process water in industrial plants.

 Due to its construction, without moving parts, this non-return valve operates relatively quietly and has an acoustic effect.
