The design characters of wafer check valve:
Check 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 valve.
3. Easy to install and maintain.
