The design characters of dual disc wafer check valveCheck valve is used for preventing the back flow of medium in pipelines and equipments. It will open and close automatically by the pressure of medium. When the medium is back-going, valve disc will close automatically to avoid accidents.1. Tightly sealed, without leakage under the water pressure testing.2. Economical, light weight, compact design-significantly lighter and less expensive than comparable swing check valves.3. Easy to install and maintain.
